The lithosphere is divided into several parts called the tectonic plates . Since they ar floating in the liquid asthenosphere , these plates tend to move , in apprisal to one another . The movements of these tectonic plates argon the main(prenominal) micturate of mountain building , volcanic activity , and earthquakesActivities caused by oftentimes occur in the plate boundaries . These are caused by the contrary types of movements between the plates . There are three different types of movement exhibited by these plates , and these movements also characterize the type of plate boundaries . These are divergent , convergent , and transform boundariesThe diverging plate boundaries are caused by the divergence or moving off of ii plates . This is known as the extensional movement . The plates coast apart each other because a plume of keen magma surfaces lease-up-and-go the crust upward , which would then force the plates to...If you want to dispirit a full essay, order it on our website: BestEssayCheap.com
