Introduction While the ancient fossils on different continents were often similar or identical, the exploring naturalists were finding out that living plants and animals on the different continents were often very different. The naturalists were discovering whole new groups of animals and plants on nearly every island and continent they visited. Most biological species seemed to be unique to the region or continent in which they were found. How could these seemingly contradictory observations be reconciled? Plate tectonics provided the…...

What is an earthquake? The definition of an earthquake is a violent vibration of the Earth that is caused by the sudden release of energy, usually as a result of faulting, which involves the displacement of rocks along fractures. They occur when rocks have been placed under huge amounts of pressure, for example if you take the rocks in the lithosphere, if the pressure increases very slowly, they will deform slightly. However, the problem is that all solids have a…...

Explain How Folding Impacts on Landscape Development
Words • 389
Pages • 2
Plate tectonics help us to explain the process of folding. According to the theory of plate tectonics, the earth’s crust is broken up into sections called plates. These plates float on the semi-molten mantle. Thermal convection currents in the mantle drag these plates in different directions resulting in tectonic activity. Folding occurs when rock layers that were originally horizontal are bent into a series of wave-like folds. As a result of this collision of the earth’s tectonic plates, the rocks…...

Maps show the east coast of South America and the west coast of Africa providing the evidence that the continents may have being joined together, then broken apart and moved to their present locations. In the earth, a fault is a line of fracture in the rocks where the two sides move by each other. The movement can be up, down or sideways, and it is caused by pressure and tension in the rock. When a sudden movement happens along…...

At the moment our not so-silent earth seems to be a perfect place where life dwells upon. But in reality, things are really different. This smooth and a solid ground can, at any moment, shake and tremble because of an earthquake. The buildings and highways can easily be destroyed if a mountain rumbles and hot lava erupts. The climate and the working, or in short, the geography of the whole world can change anytime. Questions as to what is the…...

There are many different reasons why the earth's crust is moving. Some for example are the friction between two plates causing major earthquakes. Sometimes when this plates are pushed together they form fold mountains or ridges. Today we know that the continents are gradually moving apart. Therefore the there is new rocks created in between those areas. New volcanoes are created and new rocks are formed. Plate tectonics allow scientists to know about the earth's centre. The oceanic plate slides…...

1. What produced the iron in the Earths core and the heavier elements like gold and silver in the Earths crust? The production of iron in the earth’s mantle is like the production of iron in extremely massive stars. Shells of nuclear fusion happen in the core of the earth which produces iron, the end product of the fusion. The abundance of iron in the earth’s core is due to the fact that iron has the most stable atomic nucleus…...

Topographical Features at Divergent and Convergent Plate Margins
Words • 1073
Pages • 5
Divergent and convergent plate margins are both studied in plate tectonics; which is the study of the plates that makeup the lithosphere, their movements and how these movements has influenced changes in the surface’s topography (Strahler, 2011, 389). The driving force that causes these plate movements is the gradual movement of the semi-molten rock that makes up the asthenosphere (Kious, 1996, 28). Features observed at these margins share some similarities but, also vary quite largely. These differences are caused by…...

If the process of plate tectonics were to completely stop then the ability of the Earth to create mountains through the collisions of two different plates would stop as well. This would mean that erosion would eventually abrade these mountains and the amount of sediment created by this activity would eventually reach the numerous oceans and seas. The end result would be a rise in sea level that would eventually swallow up the entire land mass of the Earth and…...

Although friction may seem like a minor issue, its absence would chance life as we know it. There would be many negative effects of this like not being able to gain traction on any surface and your ipods earplugs always falling out. Also, there would be many positive effects, such as eliminating the need for coolant in engines and lubricant in machines. Moreover, the absence of friction would be both bad and good. Without friction, many obvious things which we…...

‘Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events’ In 1912, Alfred Wegener published his theory that a single super continent named Pangaea once existed about 300 million years ago. He proposed that Pangaea then later split into two continents of Laurasia in the north and Gondwanaland in the south and that today’s continents were the result of further splitting of these two land masses. Where the plates split are known as plate…...

Has the Earth been static since the beginning of time? Well, Earth hasn't been moving vigorously but it is changing at a steady rate. New geological features, rock formations, and locations of plates all rise and demolish some in a lifetime and others over a span of millions of years. Earth is dynamic; it constantly progresses and doesn't rest. Through the churns and molds, the twists and turns, Earth is active because of plate tectonics and the rock cycle. The…...

Volcanic and Seismic Events as Proof of Plate Tectonic Theory
Words • 2628
Pages • 11
Volcanic and Seismic events are major pieces of evidence towards proving that plate tectonics theory is valid. A seismic event is the transient motion and release of kinetic energy caused by sudden failure of the earth's crust, usually felt as shaking or tremors in the rock mass. Seismic events range in size from barely perceptible tremors to major earthquakes. Volcanic events occur when there is a release of magma, gas and ash from the Earth’s crust. The entire outer surface…...
