Explain how internal energy of the Earth causes matter to cycle through the magma and the solid earth.

The Rock Cycle

Igneous

Sedimentary

Metamorphic

4

Three Major Rock Groups

Igneous Formed from melted or molten rock

There are two types of igneous rock Plutonic or Intrusive

◦ This forms from magma which undergoes slow cooling and crystallization below the surface

Volcanic or Extrusive ◦ This forms from lava which undergoes quick

cooling at the surface

Igneous Rocks

ObsidianPumice

Sedimentary These rocks form from small pieces of

materials which collect, and over time become cemented together as rock

These are formed at the Earth’s surface

Two Types Clastic

◦ These form from mineral fragments or clays Chemical

◦ These form from crystals or biochemical precipitates

Sedimentary Rocks

Sedimentary Rocks

Metamorphic◦ These types of rocks have been changed by

pressure, temperature and fluids.

• The rock cycle demonstrates the relationships among the three major rock groups

• It is powered by the interior heat of the Earth

• It involves processes on the Earth’s surface as well as the Earth’s interior
