Then human beings become aware of the awesome forces that are shaping Their planet. These forces are fuelled by three powerful sources of energy - heat from within the Earth‚ heat from the Sun‚ and the force of gravity.

Geographers are interested in locational aspects of Earth phenomena (can it be mapped?) * Physical geography involves natural phenomena * Human/cultural geography involves phenomena caused by inhabitants Many different fields of geography overlap one another. All geographers are interested in: * A focus on spatial relationships (terrestrial) * Geographic

volcanic eruptions‚ earthquakes‚ tsunamis‚ and other geologic processes. A natural disaster can cause loss of life or property damage‚ and typically leaves some economic damage in its wake‚ the severity of which depends on the affected population’s resilience‚ or ability to recover.[1] An adverse event will not rise to the level of a disaster if it occurs in an area without vulnerable population.[2][3][4] In a vulnerable area‚ however‚ such as San Francisco‚ an earthquake can have disastrous consequences

chamberbelow the surface. On Earth‚ volcanoes are generally found where tectonic plates are diverging or converging. Amid-oceanic ridge‚ for example the Mid-Atlantic Ridge‚ has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast‚ volcanoes are not usually created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching

INTRODUCTION: The Ring of fire (figure 1) is a horse shoe shaped fault line. This fault line is prone to Earth quakes and volcanic eruptions. The ring of fire Is home to 452 volcanoes and 75% of the worlds dormant and active volcanoes live on the Ring. PLATE TECTONICS Plate tectonics is a theory that the earth is split up in to different areas of the world. They glide on the mantle of the earth the plates act like a hard ridged shell (fig 2 plate tectonics) Some of the plate tectonics move very

start off small and become big as they move from the ocean to the shore. In addition‚ they were formed by different natural disasters. Tsunamis can be formed from different activities‚ such as earthquakes‚ landslides‚ and volcanoes on the deep ocean floor. If oceanic activity is detected‚ such as an earthquake or a volcanic eruption below the surface‚ then you can often predict that a tsunami may

there is a large displacement of water. Based on the article‚ “Tsunamis are caused by landslides‚ volcanoes‚ or earthquakes that occur on the ocean floor” (Simmons 61). A tsunami could be caused deep underwater from an earthquake or the rumble of a volcano‚ and even from the effect of a landslide. Finally‚ tsunamis are a bunch of enormous waves caused by natural disasters like earthquakes‚ volcanoes‚ landslides‚ and even meteorites. Rogue waves and tsunamis share many causes and effects‚ but both

Spanning the Mid-Atlantic Ridge‚ Iceland emerged as a result of the divergent process; the results of which‚ can be measured and observed on land. About the size of the State of Virginia‚ with a population of around 300‚000. Iceland has 30 volcanoes and 13 of them are active. The most fatal volcanic eruption of Iceland’s history was the Skaftáreldar in 1783-84 (fires of Skaftá). Almost a quarter of the population died. The immediate lava flow was not the cause of the deaths. The deaths occurred

the rising magma from the mantle. The GARV is an example of where the crust has dropped down between parallel faults to form rift valleys. As the crust subducts into the mantle it melts causing igneous activity below‚ magma to rise and therefore volcanoes erupt on the surface as a result. Evidence of this volcanic activity is shown by Mount Kenya and Mount Kilimanjaro. The lava here has a low viscosity‚ it very hot (1200 C) and has a low silica content. An example
