    ENDOGENETIC PROCESS: The Endogenetic processes are the processes that shape the land by forces coming from within the earth (Endogenetic forces). There are 3 main Endogenetic processes: folding‚ faulting and volcanism. They take place mainly along the plate boundaries‚ which are the zones that lay on the edges of plates. These zones are weak. Endogenetic processes cause many major landform features. MOVEMENTS: The forces coming from within the earth cause two types of movements in the earth.

Water’s ability to hold heat aids in cooling the erupting lava quicker than it would when exposed to the air (Mitchell 444). This article is important in order to further research by geologists and oceanographers‚ making this an interdisciplinary
