ROCKS AND ROCK CYCLE

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of transformation of rocks from one type to another, including igneous, sedimentary, and metamorphic rocks.

Front

What are the three major types of rocks?

Back

Igneous, Metamorphic, Sedimentary.

Front

What is an igneous rock?

Back

Igneous rocks are formed from the cooling and solidification of magma or lava.

Front

What is a sedimentary rock?

Back

Sedimentary rocks are formed from the compaction and cementation of sediments, which can include fragments of other rocks, minerals, and organic material.

Front

What is a metamorphic rock?

Back

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

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces due to environmental factors 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, often by water, wind, or ice.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things, often formed through weathering.

Front

What is compaction?

Back

Compaction is the process by which sediments are pressed together under pressure, reducing their volume.

Front

What is cementation?

Back

Cementation is the process by which dissolved minerals crystallize and glue particles of sediment together.
