it. Earthquake occurrence happens because of plate tectonics. Plate tectonics says that the Earth's lithosphere is broken into a mosaic of oceanic and continental plates which can slide over the aesthenosphere, which is the uppermost layer of the mantle. The plates are in constant motion. Where they interact important geological processes take place, such as the formation of mountain belts, earthquakes, and volcanoes. Therefore, the movement of the plates causes most earthquakes that happen around

Sedimentary Rocks Your Name Plate tectonics affect where sediment falls to the way that rocks are formed from the sediment. There are three different types of sediment rocks that are created in a similar manner but actual make up of each sediment rock is very different. There is clastic sediment that will form clastic sedimentary rock, chemical sediment that will form chemical sedimentary rock, and then there is Biogenic sediment that will eventually form Biogenic sedimentary rock. This

apart on their crustal plates, held afloat by the fire beneath. That is a poetically turned phrase from Lewis Thomas, which beautifully sums up the mechanics behind plate tectonics, and ultimately behind earthquakes. The following is a brief sketch on earthquakes, their cause and effect, how they are measured, and an area where they frequently occur. Plate Margins There are two different plate margins. These are convergent margins and divergent margins. When two plates move and finally come

The distribution of species and ecosystems in geographic space and through geological time. 3. What is genetics? How is it a unifying theme in biology? Genetics is the scientific study of heredity. 4. What is plate tectonics? How is it a unifying theme in earth science? Plate tectonics is the theory that pieces of Earth's lithosphere are in constant motion, driven by convection currents in the mantle. 5. What is the Big Bang theory? How is it a unifying theme in astronomy? The theory that the

Government Parliamentary democracy and a Commonwealth realm | Political Stability | What happened? | Magnitude / LocationSeptember 4th earthquake occurred along an east-west fault (not Alpine Fault), associated with the motion of the two tectonic plates. Fault that caused the earthquake was under the Canterbury Plains- flatlands between the Southern Alps and the Pacific Ocean. The quake was centred around 45km west of Christchurch. February 2nd epicentre was 10km away from Christchurch with a

Instability in the Himalayas: Earthquake in Nepal All life is at the mercy of nature. Whether it feeds and nurtures a species, or drives it to extinction, all life on earth is controlled by the forces of the natural world. There are many examples of the violent and catastrophic effects of natural disasters, but perhaps none is more relevant to the present than earthquakes. There are “only about 15 earthquakes a year in the world — out of 1.3 million total temblors — are magnitude-7.0 or higher

place at the boundaries by which one tectonic plate moves under another tectonic plate. The tectonic plates push against each other, causing a build up of pressure, which causes dramatic movement. The Indian Ocean Tsunami was located 250 kms off the West coast of Sumatra, Indonesia. The process of the Indonesian Tsunami was caused by the denser Indo-Australian plate was moving east while grinding against the lighter Burma tectonic plate and this caused the Burma plate to move about six centimetres a year
