Gondwana: Nothofagus or Southern Beech. A genus of around 40 extant species of trees. 3. Describe the theory of plate tectonics and identify its role in the formation of Australia as an island continent: The theory of plate tectonics states that Earth’s crust and the outermost part of the mantle are mechanically connected to each other. This layer is broken into several plates that move about Earth’s surface. As they move about‚ they are constantly interacting with each other along their boundaries

Over time plate movement or subduction causes increasing strain on "sticking points" within the crust. Similar to if you rub two pieces of sand paper together‚ they will initially resist sliding until enough strain is built up. At that point‚ the "sticking point" is weakened and releases the built up strain. Before this theory was developed‚ scientists were unsure whether earthquakes caused faulting (plate movement) of faulting caused earthquakes. Today‚ over

Deirdre Coffield English 090-B10 July 26‚ 2010 Earth vs. humans When the earth began it was filled with gases and molecules. Then there was water‚ plants and animals and years ago man came. Through the years humans have evolved beyond our expectations‚ while this is exciting we have caused damage and deterioration to our environment. From the air we breathe to the water we drink and the animals we consume‚ the environment is constantly being affected. First the very stuff we breathe

now on a collision course with a smaller plate once connected to Africa and South America‚ known as the Caribbean plate. For years and years to come following the convergent plate’s activities; thrust faults and folds piled up marine sediments and rocks‚ which resulted in an orogenic process which lead to the building up of the Ouachita-Appalachian mountain system. This was one of the final events in the formation of Pangaea. Once the collision of the plates stopped‚ exposure and uplift occurred with

Over 13.5 billions years ago‚ a gigantic explosion produce energy and fundamental particle that created the universe. This mean that all the things that we see today such as rock‚ animal‚ plant‚ water was created during that time. First‚ quark is formed which is proton

Fold Mountains are formed when two tectonic plates collide at convergent plate boundaries. During this process the less dense crust to float over the denser plate. The material is then forced upwards

chain of waves. The main cause of tsunamis are submarine earthquakes. These are most common at subduction zones. Friction between subducting plates causes a build-up of pressure‚ eventually this pressure is released causing an earthquake. These submarine earthquakes can displace huge volumes of water. On the 26th December 2004 at the Indian plate/ Burma plate subduction zone‚ lots of pressure was suddenly released north-west of the coast of Sumatra‚ resulting in a megathrust earthquake of 9.1 on the
