Cause and Effect Paragraph

     Have you ever thought about what makes a volcano erupt or what happens
afterward? When the temperature rises deep under the  Earth’s crust, it becomes
hot enough to melt rock and turn it into magma. Sometimes this melted rock blasts
through the Earth’s surface, which causes rock, ash, and deadly gases to fly into
the air. The lava that flows out of the volcano can knock down trees and destroy
houses and even whole towns.  Although volcanoes can cause lots of destruction,
the volcano’s eruption also  creates new land. Many times this new land forms 
an island in the ocean. You  might even live on land created by a volcano.
