1. Continental Drift
is the theory that the positions of the earth's continents have changed a lot through geologic time. The German meteorologist Alfred Wegener proposed the first comprehensive theory of in 1912, on the basis of the way the continents fit together on the opposing Atlantic coasts and paleontology correlation on both sides of the Atlantic. He proposed t
2. Observed Distribution Of South American Relief Features
The land below us is always in motion. Plate tectonics studies these restless effects to give us a better understanding of the Earth and its past. New molten rocks are poured out in the form of magma from the mid-ocean ridges. The rock is recycled and re-entered back into the earth in deep ocean trenches through convection current. The convection c
3. How Earthquakes Are Caused
When any two plates collide, some sort of activity is bound to take place. A specific type of boundary is a convergent plate boundary. At this type of boundary, two plates are moving towards each other. Neither plate is subducted into the mantle. Many things happen when plates drive into each other. Including volcanic activity. When two continents
4. NASCAR Speech
NASCAR....ever heard the word before? I know I have! To you it just might seem like some new kind of car or something. But to me, it means a lot.

5. How Mountains Are Formed
Mountains are formed over long periods of time by forces of the earth. Mountains just don’t appear in any place. Most are formed when plates, or huge pieces of the Earth’s crust, pull and push against each other. Great mountain ranges are formed by the movement of tectonic plates. Convection currents deep in the mantle of the earth
