Plate Tectonics Press Release GLG/101 July 13‚ 2012 Plate Tectonics Press Release Hello everyone‚ my name is John doe and I am the Director of Earthquake Preparedness’ for Los Angles. I am here today to talk to your about earthquake preparedness. During this press release I will be describing the hazards associated with earthquakes in Los Angeles. I will discuss the origin and causes of earthquakes and the relation of earthquakes to plate tectonics and faults in Los Angeles

The Structure of the Earth and Plate Tectonics Structure of the Earth Mantle • The Earth is made up of 3 main layers: Outer core Inner core – Core – Mantle – Crust Crust The Crust • This is where we live! • The Earth’s crust is made of: Continental Crust Oceanic Crust - thick (10-70km) - buoyant (less dense than oceanic crust) - mostly old - thin (~7 km) - dense (sinks under continental crust) - young How do we know what the Earth is made of? • Geophysical surveys: seismic‚ gravity‚

Alfred Wegener(1880-1930) was the first man to propose the theory gplate tectonics.h He had got a Ph.D in astronomy from the University of Berlin‚ but he was also interested in the other science field such as geophysics‚ meteorology‚ and climatology. He also contributed to meteorology by establishing to track air circulation using balloon. In 1911‚ he read a paper that listed identical fossils of plants and animals found on opposite side of the Atlantic‚ and he looked for more of such organisms

ago planet Earth did not look like it does today‚ it was covered in lava and volcanoes. There was no possible way that life could exist on the planet. However‚ eventually the planet started cooling down; huge amounts of steam rose causing clouds. Then the clouds rained. One thousand years of continuous raining caused oceans which made earth like it is today. Planet Earth‚ also known as the blue planet‚ has oceans covering three quarters of the Earth’s surface. Oceans have a system to try and keep

AEOLIAN LANDFORMS * Aeolian landforms (also spelled as eolian or æolian) are features of the Earth’s surface produced by either the erosive or constructive action of the wind. * This process is not unique to earth‚ and it has been observed and studied on other planets‚ including Mars. * The word derives from Æolus‚ the Greek god of the winds‚ and the son of Hellen and the nymph Orseis. * Aeolian processes pertain to wind activity in the study of geology and weather‚ and specifically

Plate Tectonics Press Release GLG.101 August 16‚ 2013 Plate Tectonics Press Release Natural destroys are a part of the nature of the world. There are many different kinds of natural destroys hurricanes‚ tornados‚ tropical storms‚ and earthquakes. The great state of California is no stranger to its part of natural destroyers. Many cities in the state have had its share having earthquakes. Earthquakes are produced by abrupt motion along a fault when friction that resists such motion is overcome

Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events(40) The global seismic and volcanic activity is concentrated along the margins of the earth’s plates‚ which are broken pieces of the crust and are moved by convection currents that are caused by heat rising and falling inside the mantle generated by radioactive decay in the core. This movement of the plates and the Earth’s inner activity is called plate tectonics and can cause seismic and

some of the planet’s highest peaks‚ including the highest‚ Mount Everest. The Himalayas include over a hundred mountains exceeding 7‚200 metres (23‚600 ft) in height. By contrast‚ the highest peak outside Asia—Aconcagua‚ in the Andes— is 6‚961 metres (22‚838 ft) tall.[2] The Himalayas have profoundly shaped the cultures of South Asia. Many Himalayan peaks are sacred in both Hinduism and Buddhism. Besides the Greater Himalaya of these high peaks there are parallel lower ranges. The first foothills reaching
