eLearning_ES_Weathering and Rocks Review

Jennifer was investigating granite, a type of rock that forms when magma deep below the Earth's crust cools off and hardens. What type of rock is granite?

• bedrock

• igneous

• sedimentary

• metamorphic

Shale is formed from clay, silt or mud particles that have been compacted together by pressure. What type of rock is shale?

• bedrock

• igneous

• sedimentary

• metamorphic

Granite is a coarse or medium-grained rock that is rich in quartz and feldspar. It is formed when bodies of magma cool and harden deep below the earth. What type of rock is granite?

• bedrock

• igneous

• metamorphic

• sedimentary

Sedimentary rock is formed when rock fragments, minerals, and the remains of plants and animals are deposited as sediments and are then

• chemically weathered by water.

• compacted and cemented together.

• recrystallized under the weight of the layers.

• melted due to increased temperature and pressure.

Foliation can develop in a rock as a response to intense heat and pressure. This rock should be classified as

• banded.

• igneous

• metamorphic

• sedimentary

Jill's teacher made a peanut butter and jelly sandwich and explained that one type of rock is formed when layers of sediment are squeezed and cemented together. After the rock is formed, you can still see the layers in the rock. What kind of rock is described?

• mineral rock

• igneous

• metamorphic

• sedimentary

If igneous rock forms above ground after a volcanic eruption, it ________________ forming ____________ igneous rock, such as obsidian which is a naturally occurring volcanic glass.

• cools quickly, extrusive

• cools quickly, intrusive

• cools slowly, extrusive

• cools slowly, intrusive

____________ rocks that are changed by heat and pressure

• igneous

• metamorphic

• sedimentary

• mineral

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place.
• makes the rocks last longer.
• expands cracks and breaks rocks.
• causes rocks to fall in landslides.
