Describe the formation of igneous, sedimentary, and metamorphic rocks?


Question asked by: heritage

Asked on: 05 Jul 2008

Igneous rocks are formed through volcanic action and as a result of volcanic activity.

Sedimentary rock takes a long time to form and is basically dead bits of animals laid down in the sea and compressed over millions of years to form rock; anywhere you see sedimentary rock you are seeing the remains of creatures that were once in the ocean a long time ago.

Metamorphic rock is formed through a combination of heat and pressure inside the earth.
