Rock Classification Flashcard

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which weathered rock and soil are moved from one place to another, often by water, wind, or ice.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How do igneous rocks form?

Back

Igneous rocks form from the cooling and solidification of molten rock (magma or lava).

Front

What are sedimentary rocks made of?

Back

Sedimentary rocks are made of particles and organic materials that have been compacted and cemented together.

Front

What is a metamorphic rock?

Back

Metamorphic rocks are formed when existing rocks are changed by heat, pressure, or chemical processes.

Front

What is the role of ocean waves in rock formation?

Back

Ocean waves can erode rocks along the coast, breaking them down and forming features like sea caves.

Front

What is a sea cave?

Back

A sea cave is a cave formed by the erosion of rock along a coastline, often created by the action of ocean waves.

Front

What is the difference between renewable and nonrenewable resources?

Back

Renewable resources can be replenished naturally over time, while nonrenewable resources are finite and cannot be replaced once used.

Front

What is an example of a nonrenewable resource?

Back

Phosphate is an example of a nonrenewable resource, as it cannot be replenished on a human timescale.
