Fault Lines

As these plates slowly move about, they interact with each other, forming boundary zones. Each of these different types of plate boundaries produces unique geographical features on the surface, including fault lines, trenches, volcanoes, mountains, ridges and rift valleys. A transform boundary connects two diverging boundaries, creating a fault line. This line represents an area of geologic features of divergent boundaries, where two plates are moving horizontally against one another. Trenches are geological features formed by convergent boundaries. When two tectonic plates converge, the heavier plate is forced downward, creating a subduction zone.

This process results in the formation of a trench. The Marianas Trench is an example of a trench formed by the convergence of two oceanic plates. The deepest part of this trench, called the Challenger Deep, is over 36, feet deep, deeper than Mount Everest is tall. Another geological feature that results from a subduction zone is volcanoes.

When the plate being forced downward begins to melt, this magma rises to the surface, forming volcanoes. Mount Saint Helens is an example of a volcano formed by an oceanic plate that is subducting under the North American continental plate.

When two oceanic plates converge, both a trench and a string of volcanoes are formed. These volcanoes can build to produce island chains, such as the Mariana Islands, which are located alongside the Marianas Trench. When two continental plates converge, neither of the buoyant plates is able to give way and subduct beneath the other.

This results in a powerful collision that produces tremendous, crushing pressure. Ultimately, this pressure causes large vertical and horizontal displacements, forming towering mountain ranges. The Himalayas, one of the tallest mountain ranges in the world, is an example of a geological feature that is formed when continental plates collide. Opposite of a convergent boundary, a divergent boundary is formed by geologci spreading of a tectonic plate.]
