What is the role of energy in rock formation?

Back

Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, while energy from the sun causes rock to weather into small pieces.

Front

What type of rock is formed when sediments are pressed and glued together?

Back

Sedimentary rocks.

Front

Rocks formed from the cooling and solidification of molten rock (magma or lava).

Front

What are sedimentary rocks?

Front

What are metamorphic rocks?

Back

Rocks that have been changed from their original form due to heat, pressure, or chemically active fluids.

Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

The process by which weathered rock and soil are moved from one location to another by wind, water, or ice.
