What are Earth Processes?
• Forces within the earth• How earthquakes and volcanoes are related to
movements inside the earth– Both release great amounts of energy
that can have effects on the Earth’s surface
• Both can have devastating effects– Most recently in seen in Japan

Earthquakes
• Rocks move and break along surfaces called faults
• Vibrations caused by rocks breaking along faults
• Usually results from plates (large pieces of the Earth) that are moving under, over or past each other

Volcanoes
• Opening in Earth’s surface – Can form a mountain
when layers of ash and lava build up
• Are found where plates (large pieces of the Earth) are moving apart or together or at hot spots
• Most of Earth’s volcanoes are not active
