Volcanoes: Assignment

Constructive & Destructive Forces

Through constructive and destructive forces, Earth’s landscape is constantly built up and torn down.  Violent events such as volcanoes and earthquakes can change the landscape suddenly, while more subtle processes, like weathering, will slowly change the Earth’s surface.  Destructive forces are processes that break down the Earth.  To scientists, volcanoes are known as “constructive” forces. That is, volcanoes often result in the construction of new landforms.
