Rocks and Minerals Study Guide

What are the three main types of rocks?

• granite, limestone, and shale

• volcanic, sandstone, and slate

• basalt, conglomerate, and marble

• igneous, sedimentary, and metamorphic

Which type of rock is formed from the cooling and solidification of magma or lava?

• sedimentary rock

• metamorphic rock

• igneous rock

• granite

What are the two main categories of igneous rocks?

• volcanic and plutonic

• intrusive and extrusive

• sedimentary and metamorphic

• granite and basalt

How are intrusive igneous rocks formed?

• Magma cools and solidifies on the Earth's surface.

• Magma cools and solidifies beneath the Earth's surface.

• Intrusive igneous rocks are formed by erosion and weathering.

• Intrusive igneous rocks are formed by the deposition of sediment.

How are extrusive igneous rocks formed?

• Molten lava cools and solidifies deep within the Earth's crust.

• Molten lava cools and solidifies on the Earth's surface.

• Extrusive igneous rocks are formed through the process of erosion and sedimentation.

• Extrusive igneous rocks are formed by the compression of sedimentary rocks.

Which type of rock is formed from the accumulation and compaction of sediments?

• volcanic rock

• sedimentary rock

• metamorphic rock

• igneous rock

What are the three main types of sedimentary rocks?

• hard, soft, and medium

• granite, limestone, and sandstone

• igneous, metamorphic, and volcanic

• clastic, chemical, and organic

How are clastic sedimentary rocks formed?

• From the accumulation and lithification of fragments of pre-existing rocks or minerals.

• From the evaporation of water leaving behind minerals.

• From the deposition of organic material.

• From the cooling and solidification of molten rock.

How are chemical sedimentary rocks formed?

• Through the cooling and solidification of magma

• Through the precipitation of minerals from water solutions

• Through the compaction and cementation of organic materials

• Through volcanic activity

How are organic sedimentary rocks formed?

• From the accumulation and lithification of organic material

• From the evaporation of water

• From the compression of minerals

• From volcanic activity
