An underwater volcano is an example of a constructive and destructive process because it can form islands and destroy coral reefs: True or False True
How could human interaction decrease the destructive force of hurricanes on coastal areas? create levees to control water flow

divergent plate boundaries plates move in opposite directions can result in mountains and valleys
Examples of erosion: the movement of sediment (broken down rock) ex. Grand Canyon
