A plateau is formed by a process of geological uplift, either due to the collision of continental plates, pressure from magma below or the burial of land by volcanic lava and ash flows, resulting in a high, flat surface. These are very similar to processes that give rise to mountains and mountain ranges. The only major difference is that a plateau is flat while mountains are peaked.Continue Reading
Plateaus are found all over the world. The Colorado plateau in the United States is an example of a plateau formed by volcanic activity. These plateaus show a great abundance of volcanic rocks and other telltale signs. The other two types only have the marks of the terrain before they were uplifted.
One of these is the Ethiopian Plateau in Africa, which was created by magma uplift. This plateau and other similar plateaus often do not show any signs of volcanism, as these signs only occur when magma actually breaks through.
The last type, and the one with the greatest potential elevation, is the crustal collision type. One well-known example of this is the Tibetan plateau. This plateau, and others like it, can be so high that they are forbidding for many forms of life, with thin air and cold temperatures.Learn more about Geology
A lava plateau is a large, flat area of land created by lava filling in all the valleys and other depressions. Lava plateaus are created by low-viscosity basaltic magma, which spreads very quickly before it cools, allowing it to cover a large area.Full Answer >
In geology, uplift refers to a considerable vertical movement of the Earth's crust and is one of the primary factors in the formation of mountains and other prominent landscape features. Some of the more spectacular examples of uplifts in the Earth's crust are the results of tectonic plate interactions that are involved in the process called orogenesis. Major mountain ranges, such as the Alps, were produced by the orogenic uplift resulting from a collision of one continental plate with another.Full Answer >
Discovering Fossils states that the conditions necessary for fossil formation include rapid burial, ample sediment accumulation and eventual bedrock uplift. Time is also an important factor because fossils develop over millions of years. According to UK Fossils, most fossil discoveries occur at beaches, mines and quarries.Full Answer >
The type of rock that works best as an aquifer is volcanic rock that fills in as rubble between flows. This type of rock is highly porous and rather permeable, permitting significant water movement.Full Answer >
