Rock Cycle Soil Weathering

Rock formed from sediments, such as sand, pebbles, shells and remains of dead plants / animals; often deposited in layers

• Regolith

• Sedimentary Rock

• Igneous Rock

• Metamorphic Rock

Rock formed from liquid molten rock (lava or magma) that cools slowly and hardens. Found near volcanoes and fissures; can have crystals.

• Metamorphic Rock

• Igneous Rock

• Sedimentary Rock

• Regolith Rock

Fossils (the remains or impressions of prehistoric organisms preserved in petrified form or as molds or casts) are found in ___________ rocks only.

• Igneous

• Metamorphic

• Sedimentary

• Iron Oxide

The process necessary to form a metamorphic rock:

• uplift, weathering, erosion

• heat and or pressure

• burial and cementation

• compaction
