Rock Cycle Review

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various stages: igneous, sedimentary, and metamorphic.

Front

What are igneous rocks?

Back

Igneous rocks are formed from the cooling and solidification of magma or lava. They can be classified as intrusive (formed inside the Earth) or extrusive (formed on the surface).

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles, often in bodies of water.

Front

What are metamorphic rocks?

Back

Metamorphic rocks are formed from existing rocks that undergo changes due to heat, pressure, or chemically active fluids.

Front

What is magma?

Back

Magma is molten rock located beneath the Earth's surface. When it erupts, it is called lava.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks cool slowly beneath the Earth's surface, resulting in larger crystals, while extrusive igneous rocks cool quickly on the surface, resulting in smaller crystals.

Front

What is sedimentation?

Back

Sedimentation is the process by which particles settle out of a fluid, leading to the formation of sedimentary rocks.

Front

What is lithification?

Back

Lithification is the process of turning sediment into rock through compaction and cementation.

Front

What is erosion?

Back

Erosion is the process by which rocks and soil are worn away and transported by natural forces such as water, wind, or ice.

Front

What is weathering?

Back

Weathering is the breakdown of rocks at the Earth's surface due to environmental factors like temperature changes, water, and biological activity.
