Rock and the Rock Cycle

Fossils are only found in

• Sedimentary rocks

• Foliated Metamorphic rocks

• Igneous Rocks

• Nonfoliated Metamorphic rocks

How does a Metamorphic rock become a Sedimentary rock?

• Heat, pressure and radiation

• Melting, cooling and evaporation

• Weathering, Erosion, Compaction and Cementation

• Cooling of Magma over time

Igneous and metamorphic rock are similar in that they both

• form from magma cooling

• require a lot of heat

• form from sediments

• are formed from pressure

Define Igneous rock

• Rocks form when particles of other rocks are deposited in layers and are compacted and cemented together.

• Formed when lava or magma cools and solidifies. Lava cools quickly, magma cools slowly.

• Formed deep underground where heat and pressure cause existing rocks to be changed.

• Occurs when rock particles are pressed together or packed down by gravity and overlying rocks

Compaction is:

• Earth’s rocks change from one type into another over time due to various Earth processes

• Continuous force exerted on or against an object

• Rocks form when particles of other rocks are deposited in layers and are compacted and cemented together

• Occurs when rock particles are pressed together or packed down by gravity and overlying rocks
