Exploring Rock Types and Formation

What is the primary process that forms sedimentary rocks?

• Melting and cooling

• Compaction and cementation

• Heat and pressure

• Crystallization

Which of the following processes is involved in the formation of metamorphic rocks?

• Erosion

• Melting

• Heat and pressure

• Deposition

How are igneous rocks formed?

• By the cooling and solidification of magma or lava

• By the accumulation of sediments

• By the alteration of existing rock through heat and pressure

• By the evaporation of water

Which characteristic is used to identify minerals?

• Color

• Hardness

• Streak

• All of the above

Explain how sedimentary rocks can become metamorphic rocks in the rock cycle.

• By melting and cooling

• By being subjected to heat and pressure

• By weathering and erosion

• By crystallization

Describe the process that leads to the formation of igneous rocks from magma.

• Erosion and deposition

• Cooling and solidification

• Compaction and cementation

• Heat and pressure

Which of the following is a key difference between igneous and sedimentary rocks?

• Igneous rocks are formed from magma, while sedimentary rocks are formed from sediments.

• Igneous rocks are formed by heat and pressure, while sedimentary rocks are formed by cooling.

• Igneous rocks are formed by compaction, while sedimentary rocks are formed by melting.

• Igneous rocks are formed by erosion, while sedimentary rocks are formed by crystallization.

Analyze how the rock cycle demonstrates the interrelationship between different rock types.

• It shows that rocks can only change into one other type.

• It illustrates that rocks can transform into any other type through various processes.

• It indicates that rocks remain the same over time.

• It suggests that rocks can only become sedimentary rocks.

Evaluate the role of minerals in determining the characteristics of rocks.

• Minerals have no effect on rock characteristics.

• Minerals determine the color, hardness, and texture of rocks.

• Minerals only affect the size of rocks.

• Minerals are not present in rocks.

Predict what might happen to a sedimentary rock if it is subjected to extreme heat but not enough to melt it.

• It will become an igneous rock.

• It will become a metamorphic rock.

• It will remain a sedimentary rock.

• It will evaporate.
