Effects of Internal Geoprocesses

By just barely looking at the things around us, like the mountains, valleys, etc., it seems like earth’s crust is very stable. It seemed that there was no movement happened. That mountain appears by itself, so as with the other land forms. But, to those people who believe that there is a pressure strong enough to bend rocks and heat hot enough to melt rocks beneath the earth’ crust, everything happened for a reason. These processes tend not to end. In fact ever since the earth was born the crust has never been restless.

Theories were developed by scientists to explain these internal geologic processes. Among those theories, they accepted the Plate Tectonic Theory. This states that earth’s crust is consist of plates which are pulling away from one another, sliding or moving towards each other.

There were three types of plate boundaries based on the said movement. First is the convergent boundary, which plates move together and produce mountain ranges, like Himalayas, and trenches. Second is the divergent boundary where plates move away from each other and produces valleys. Last is the transform boundary where plates slide with one another and creates fault lines like the San Andreas Fault. Among these plate boundaries, earthquakes occur mostly.

Earth had been very amazing. Though we can’t see any actions or movements that happened beneath the crust we still believe that they really occur and results to the things that we can see around us.
