Explain how global warming leads to rising sea levels. What is Global Inequality? If this trend continues, according to Oxfam's calculations, in just six years' time the richest 1% in the region will have accumulated . system in which water moves between the cold depths and warm surface in oceans throughout the world. 338 people helped. According to their latest calculations, the Dec. 26th earthquake shifted Earth's "mean North Pole" by about 2.5 centimeters (1 inch) in the direction of 145 degrees east longitude, more or less toward Guam in the Pacific Ocean. earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth's rocks. Explain why the global distribution of earthquakes is uneven. The World's Water - Distribution of Earth's Water. Natural disasters such as droughts, hurricanes and earthquakes can hinder a country's development. rip current. This sudden release of energy causes the . Most fresh water is trapped as ice in the vast glaciers and ice sheets of Greenland. . Any particular place may be rich in the resources people desire and poor in others. But in some cases, the rock on either side of a fault slowly deforms over time due to tectonic forces. Why Do Earthquakes Happen? Typically, high-income countries (HICs) consume more than low-income countries (LICs). Earthquakes are often thought of as largely unpredictable, wholly natural forces of nature—but that may be changing. Comparing the world, the northern part and the southern part. 4 By comparison, the devastating 1906 San Francisco earthquake was felt moderately over only about 6,200 square miles. Answer to Study Fig. a strong flow of water running from the shore to the open ocean, sea, or lake. Most faults in the Earth's crust don't move for a long time. This can be voluntary migration where people search for a better life (pull factors). and more. There is only 1 African country included and 0 in Oceania. Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. Explain why uneven development exists between . At 2:15 a.m. on December 16, 1811, a magnitude 7.5 earthquake with its epicenter in northeast Arkansas was felt strongly over an area of at least 50,000 square miles and moderately across about one million square miles. India's population is estimated to be around one billion. 4 By comparison, the devastating 1906 San Francisco earthquake was felt moderately over only about 6,200 square miles. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in . Based on the occurrence rates, the selected countries were clustered into four classes. the earth is tilted on its axis, which creates seasonal differences at certain . In the second part of the answer we have to separately bring out the relation between the global distribution of fold mountains and volcanoes and earthquakes with examples. You can draw a diagram to show how they are . This is the grade 6-8 (ages 11-13) version of this lesson. Global distribution of earthquakes and volcanoes Earthquakes are located mostly in long, narrow belts, along all types of plate boundaries (or margins) as shown on this map. Volcanoes . And Rhian and Andy have already given you two great answers. If this growth rate continues it could become the world's most populated country by 2020. Resource distribution refers to the geographic occurrence or spatial arrangement of resources on earth. worldwide movement of water (currents) in the ocean. The most powerful earthquakes are associated with . Sometimes they can occur on faults or . It is relatively easy to see the relationships between earthquakes and the plate boundaries. CONCLUSION Iit should be apparent that the factors influencing the uneven distribution of population are so much varied. In the last ten years its population has increased by 181 million. The distribution of earthquakes across the globe is shown in Figure 11.7. Also, how the tectonic cycle helps to explain the global distribution of volcanoes? Others are forced to move as the result of natural disasters or wars. 6, which shows a cross section of an area affected by an earthquake. Earthquakes causes a lot of damage. There are 3 types of plate boundaries and each is associated with earthquakes. Spatial distribution focuses on the physical location of things. (1) The major disasters along the . In 2014 the richest 10% of people in Latin America had amassed 71% of the region's wealth. Others are forced to move as the result of natural disasters or wars. Global distribution of crude oil is, naturally, uneven. Access, or the lack thereof, contributes to a place's economic development, political relationships, and culture. (4) A fracture in the rocks which make up the Earth's crust A weakness in the Earth's crust through which molten magma erupts What do they help with (Earthquakes, Volcanoes or Landslides) Identify several methods; Describe them in more detail; Explain why they are useful in helping with preparedness; Analyse the pros and cons to the methods . Some countries have more resources and wealth than other countries. Less than a decade after unveiling the 'Map of Life,' a global database that marks the distribution of known species across the planet, researchers have launched an even more ambitious and perhaps . (i) The distribution of earthquakes is uneven. Stromboli, a small island north of Sicily, is one of the most active volcanoes in the world and famous for its normally small, but regular explosions throwing out glowing lava from several vents inside its summit crater. An earthquake is the shaking or trembling of the earth, caused by the sudden movement of a part of the earth's crust. If this distribution were in fact uniform over depth, the dimension estimate would approach the real δ‐value for distances smaller than the thickness of the seismogenic zone (see eqs 39-40 . In certain places they are more frequent and intense whereas in other places they are extremely rare and feeble or their effect is hardly perceptible. challenge for an analysis of SDPs. Based on the occurrence rates, the selected countries were clustered into four classes. Scientists study earthquakes because they want to know more about their causes and predict where they are likely to happen. Click to see full answer. How do earthquakes happen in Earth's tightly squeezed middle layers where pressure is far too great to allow any shifting of the rock? Fertile Land: Human settlements on large scale are at places which are more fertile and where with less efforts the agricultural yield is more. India has one of the highest population growth rates in the world. Causes: The chief cause of the earthquake shocks is the sudden slipping of rock formations along faults and fractures in the earth's crust. Studies on the occurrence of earthquakes on the globe have indicated that there are certain zones within the continents along which seis­mic […] Coal resources has huge reserves and complete varieties but uneven distribution among different grades, with small reserves of high-quality coking coal and anthracite coal; wide distribution but a great difference in wealth for different deposit locations, with large reserves in western and northern regions and small reserves in eastern and . The earth's surface is made up of two types of crust: . I think it partially also depends on the fact that during the Earth's formation all the material wasn't evenly mixed and distributed across all regions, so even during the cooling process materials were already unevenly spread out. (4) Explain how urban growth can lead to more people being at risk from flooding. Uneven development leads to people migrating. Noun. Try describe the patterns in these three maps to practice: Describe the distribution of the tropical rainforests of the world.

Tectonics. 7a) With reference to the factors shown, suggest how vulnerability in a local area can be assessed (10) b) Explain the global distribution of two major hydro-meteorological hazards types(15) Describe the pattern of life expectancy shown in this map of the UK: Describe the distribution of earthquakes shown in the map: The global distribution of earthquakes is similar to that of volcanoes. This essay aims to explore the factors which affect human vulnerability to earthquakes and suggest ways to develop resilience and reduce this vulnerability. Seismic waves are produced when some form of energy stored in Earth's crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and "slip." Earthquakes occur most often along geologic faults, narrow zones where rock masses move in . Explore the definition, uses, examples, and patterns of spatial distribution including uniform, random, and clustered distribution. ocean conveyor belt. Explain in what way unequal distribution of heat over the Earth causes variation of weather and climate. Some countries have a peaceful, stable government, and . Why Uneven Distribution. This paper analyzed the SDPs of global disasters from 1980 to 2016 through biclustering. * Social - access to services such as health . . Rising global average temperature is associated with widespread changes in weather patterns. About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. * Demographic - higher life expectancy, lower birth rate. Uneven development at different scales. Firstly, this essay will explore earthquakes, their processes and investigate their global pattern of distribution. HDI. Uneven distribution between people with resources and wealth. If a country's population is distributed in a regular pattern then we say it has an even population distribution.

However this is not always the case. e3radg8 and 2 more users found this answer . Regional and latitudinal distribution. Paper 3 Mark scheme Question number Explain how one theory of development can help an understanding of global patterns of power. Eventually, through convection currents, the magma rises to the earth surface, forming volcanoes on the folded continental plate. The distribution of volcanoes is worldwide, although they are usually perceived to only occur on Plate Boundaries (PBs). Consequences of. MS-ESS3-1. On the other . Introduction - Explain what fold mountains are. Noun. Directive: Explain - Clarify the topic by giving a detailed account as to how and why it occurred, . 4 (a) Study Fig. People who do this known as economic migrants. The distribution of earthquakes is commonly linked to the margins of global plates. An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.Earthquakes can range in size, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air and wreak destruction across entire cities. the earth is covered with primarily two completely different substances, land and water which heat and cool at different rates. They also need to know how the ground moves . The global distribution and causes of earthquakes, volcanic eruptions and tsunami. All the countries have coastlines. Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere. Mining, dam building, and fracking are among the causes. A study published in . fault plates seismic waves X Y Fig. The main challenge is not having enough resources but that the resources that do exist are unevenly distributed. Places like the USA have disproportionate economic influence. This paper analyzed the SDPs of global disasters from 1980 to 2016 through biclustering. . Access to energy resources is uneven around the world. Currents are cohesive streams of seawater that circulate through the ocean. Human Development Index. Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. Explain how the long profile and cross section of the valley of the river will change as the river flows towards the sea. causes of volcanoes and earthquakes from the source provided, showing an understanding of the processes involved and the hazards. The consumption of resources across the world varies significantly. Explain why many people live near to rivers even though it may be hazardous. It is made of 3 parts: life expectancy, Literacy Rate and GDP ADVERTISEMENTS: Read this article to learn about the Global Distribution of Petroleum. system in which water moves between the cold depths and warm surface in oceans throughout the world. Directive: Explain - Clarify the topic by giving a detailed account as to how and why it occurred, . Structure of the answer. Development is all about improving people's lives in a number of different fields: * Economic - employment and levels of pay. The term is frequently used interchangeably with the term climate change, though . Why is the study of earthquakes and volcanoes important? ADVERTISEMENTS: Earthquakes are distributed unevenly on the globe. When 2 continental plates collide fold mountains are formed. This type of erratic concentration creates great political stress and […] Key earthquak | SolutionInn An overview of global inequalities in the supply and consumption of resources. Accept explanations that refer to ridge push and slab pull processes. Earthquakes are unevenly distributed around the world, and victims are affected disproportionately by their negative effects. The planet is heated unevenly by the sun, mainly because. ocean conveyor belt. Study with Quizlet and memorize flashcards terms like For a named country which you have studied, describe and explain the distribution of its population., For a named area you have studied, explain why it has a low population density., For a named country you have studied, explain why the distribution of its the population is uneven. Population Distribution: This is how a population is spread out around a country or an area. Emphasis of atmospheric circulation is on the sunlight-driven latitudinal banding, the Coriolis effect, and resulting prevailing winds; emphasis of ocean circulation is on the transfer of heat by the global ocean convection cycle, which is constrained by the Coriolis effect and the outlines of continents. In LICs 4/10 deaths are in children under 15 years old whereas it is 1/100 in HICs. Some regions like Middle East (Asia) contains 60% of global reserves while countries of S.E. 1. The results indicate that the SDPs of fatality rates are more uneven than those of occurrence rates. 1.4 Earthquake Demand versus Earthquake Capacity 10 1.5 Force-based Design to Displacement-based Design 13 2 Earthquake Demand on Buildings 2.1 Seismic Design Force 15 2.2 Dynamic Characteristics of Buildings 18 2.2.1 Natural Period 18 (a) Fundamental Natural Period of Building 19 (b) Factors influencing Natural Period 20 (1) The major disasters along the . There is also a grades 9+ version on the site. Global distribution of earthquakes and volcanoes. (b) Explain why the impacts of global warming are predicted to be uneven and unfair. The theory of plate tectonics states that the crust (lithosphere) is broken into 16 slabs called plates. Describe the distribution of the areas where earthquakes caused more than 10 000 deaths between 1900 and 2011... [3] (ii) Explain why the distribution of the areas where large numbers of deaths have been caused by earthquakes is uneven. The yearly precipitation averaged over the whole Earth is about 100 cm (39 inches), but this is distributed very unevenly. Although income inequality has fallen in recent years, Latin America remains the most unequal region in the world. The Earth is a watery place. Also called thermohaline circulation. Whilst the assertion that earthquakes only occur at plate margins is broadly true, it would be overly simplistic to assume that earthquakes are more common, and more devastating at some margins than at others. The main factors responsible for unequal distribution of the world population are as under: In many parts of the world, the density of population is high while in others it is very low. Distribution: Most earthquake zones are found at, or close to, tectonic plate boundaries, often in clusters. Earthquakes. Why Do Earthquakes Happen? worldwide movement of water (currents) in the ocean. Most faults in the Earth's crust don't move for a long time. Plate tectonics changes and challenges ideas about geology. At 2:15 a.m. on December 16, 1811, a magnitude 7.5 earthquake with its epicenter in northeast Arkansas was felt strongly over an area of at least 50,000 square miles and moderately across about one million square miles. These plates are floating on magma and moving around as a result. For example, the Great Plains region of the United States is known for . Also called thermohaline circulation. Uneven development study guide by ReJJ includes 17 questions covering vocabulary, terms and more. Middle latitudes receive moderate amounts of precipitation, but little falls in . Some countries have become wealthy because of their huge reserves of fossil fuels. 4.5 Inhomogeneity of earthquake depth distribution. Development is a process of change that affects countries and their people. This sudden release of energy causes the . the movement of tectonic plates cause earthquakes. Noun. rip current. In other words, where resources are located. People who do this known as economic migrants. Personal wealth in China and India has quadrupled since 2000. The world is not an equal place.
