Rock Cycle

Learning Objectives The student will be able to predict the events in the rock cycle. The student will be able to diagram and explain the rock cycle.

All rocks are heavy. True or False

A heavy piece of rock? Think again!

All rocks are hard. True or False

False Chalk Pumice Talc

Rocks never change. True or False

False Rocks are changed by processes such as: Melting Pressure Heat Weathering and Erosion

Melting

Sedimentary rocks are formed when layers of earth have been deposited in the bottoms of bodies of water. Over time these layers are pressed together forming sedimentary rocks.

Weathering and Erosion

Metamorphic rocks were once sedimentary or igneous rocks that have been placed under tons of pressure and heat.

Igneous Metamorphic Sedimentary

A rock can be a thing of beauty. Photos by Sandra Woodruff A rock can be a thing of beauty.

How did you simulate weathering and erosion? How are sedimentary rocks formed? How are metamorphic rocks formed? How are igneous rocks formed?
