Earth Crust Molten Rock
372 wordsHow Are Mountains 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, begins to well up towards the surface. As the pressure increases, it sets the crustal plates in motion. There are different kinds of mounta...

Tectonic Plates Molten Rock
689 wordsIn 1912, Alfred Wegener, a German scientist, was the first to notice this and develop the theory of plate tectonics. He noticed that the earth's continents fit together almost like a jigsaw puzzle. This, combined with the fact that similar fossils and rock types are found on different continents separated by large bodies of water, helped him formulate his conjecture. He contended that the plates at one point formed one large continent called Pangea, which allowed like fossils and rock types to b...

Dry Land Million Years
726 wordsLife in standstill is impossible. Life was changing in the seas and developed on the shallow waters. But the conditions of dry land are much more changeable. Water environment is rather monotonous. Mountains and lowlands, swamps and deserts change their places with a dizzy (by evolutionary measures) speed on the dry land. It is impossible for a land life form to accommodate to some specific conditions hoping that flexibility will allow accommodating to new ones. These life forms had to have the ...
