ROCKS AND ROCK CYCLE

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes how rocks change from one type to another over time through processes like melting, cooling, erosion, and compaction.

Front

What are igneous rocks?

Back

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

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles.

Front

What are metamorphic rocks?

Back

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

Front

What is the process of melting and cooling in the rock cycle?

Back

Melting and cooling is the process where igneous rocks are formed from magma that cools and solidifies.

Front

What is compaction in sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, forming sedimentary rocks.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What are organic sedimentary rocks?

Back

Organic sedimentary rocks are formed from the remains of living organisms, such as plants and animals.

Front

What is weathering?

Back

Weathering is the process of breaking 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 location to another by wind, water, or ice.
