Rocks and Minerals

What are the three main types of rocks?

• granite, limestone, and shale

• volcanic, sandstone, and slate

• basalt, conglomerate, and marble

• igneous, sedimentary, and metamorphic

How are sedimentary rocks formed?

• Through volcanic activity and cooling.

• Through metamorphism of igneous rocks.

• Through weathering, erosion, deposition, compaction, and cementation.

• Through the accumulation of organic matter in swamps and bogs.

What is the process called when rocks change from one type to another over time?

• erosion

• weathering

• metamorphism

• deposition

What are the three main steps in the rock cycle?

• Weathering, erosion, and deposition; compaction and cementation; metamorphism and melting.

• Igneous rock formation, sedimentary rock formation, and metamorphic rock formation.

• Melting, crystallization, and weathering.

• Weathering, erosion, and deposition; compaction and cementation; metamorphism and melting.

• Volcanic activity, tectonic plate movement, and erosion.

How are sedimentary rocks classified?

• Based on color, sedimentary rocks are classified into three main types: red, green, and blue.

• Based on composition, sedimentary rocks are classified into three main types: clastic, chemical, and organic.

• Based on age, sedimentary rocks are classified into three main types: young, middle-aged, and old.

• Based on shape, sedimentary rocks are classified into three main types: round, angular, and irregular.

What are the characteristics of metamorphic rocks?

• Metamorphic rocks are formed from pre-existing rocks that have been subjected to high temperatures and pressures.

• Metamorphic rocks are formed from sedimentary rocks.

• Metamorphic rocks are formed from organic materials.

• Metamorphic rocks are formed from volcanic activity.

What is the process called when sediments are compacted and cemented together to form sedimentary rocks?

• weathering

• erosion

• deposition

• lithification
