What is metamorphism?

• The process by which existing rocks are transformed by heat, pressure, or chemically.

• The process of breaking down rocks into smaller pieces.

• The formation of new rocks from volcanic activity.

• The movement of tectonic plates causing earthquakes.

What is the main cause of erosion?

• Human activities such as deforestation and mining.

• Natural forces such as water, wind, and ice.

• Chemical reactions in the soil.

• Volcanic eruptions and earthquakes.

What is the process of transporting weathered materials from one location to another?

• Erosion

• Weathering

• Deposition

• Sedimentation

What is the term for the natural process of breaking down rocks?

• Pressure fluctuates.

What is the significance of the rock cycle in nature?

• It explains how rocks change from one type to another over time.

• It describes the formation of mountains and valleys.

• It illustrates the process of erosion and sedimentation.

• It outlines the types of minerals found in rocks.

What is sediment?

• Small particles of rock and organic material that can accumulate to form sedimentary rocks.

• A type of igneous rock formed from cooled magma.

• A large body of water that is deep enough to support marine life.

• A process of erosion that transports soil and rocks.
