Plate tectonic theory

Plate tectonics described with types, examples, images, & labeled diagrams. Where are they located & what causes them to move. Learn their theory.

Layers of the earth-Based on the physical conditions, the Earth can be divided into three layers. The crust is the uppermost layer of the earth.

The world is a dynamic place. The earth that we stand on, and think of as fixed, is anything but. The most unstable areas of all are the plate boundar

A plate race shows the movement of tectonic plates. Gym mats are used as the plates and students represent the mantle below. Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth’s lithosphere (crust and upper mantle), since tectonic processes began on Earth between […]

Above is a diagram of the conventional tectonic view of "subduction" -- the action of one plate supposedly diving beneath another plate. This diagram can be found on Wikimedia commons, and there are many more like it which all show roughly the same concept. According to the conventional view, when one plate runs into another, it will sometimes dive beneath the other plate, creating a trench (marked in the diagram above) along the line of subduction. Additionally, the conventional theory…

The theory, or idea, of plate tectonics says that Earth’s outer layer is made up of large, moving pieces called plates. All of Earth’s land and water sit on these plates. The…
