Lesson Summary

• There are three kinds of plate boundaries: convergent, divergent and transform.

• There are three kinds of convergent boundaries: oceanic-continental, continental-continental and oceanic-oceanic.

• The type of boundary interaction affects topography. For example, a continental-continental convergent boundary causes mountains.

• Volcanoes are often caused by oceanic-continental convergent boundaries.

• Volcanoes can cause short-term damage such as ash and fires. Volcanic eruptions can also cause climate change.

• Mountains affect the amount of precipitation nearby areas receive.

• There are four major "spheres:" atmosphere, biosphere, geosphere and hydrosphere.

• Each sphere interacts with, and affects, each other.
