Answer:
Volcanoes are renowned for their destructive power.
Explanation:
Volcanoes come in all shapes and sizes. Some volcanoes form majestic mountains, like Mt. Rainier in Washington State, and others have a very low, broad profile. Volcanic land forms are controlled by the geological processes that form them and act on them after they have formed. Thus, a given volcanic land form will be characteristic of the types of material it is made of, which in turn depends on the prior eruptive behavior of the volcano. Although later processes can modify the original land form, we should be able to find clues in the modified form that lead us to conclusions about the original formation process.
