What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various geological processes, including igneous, sedimentary, and metamorphic formations.

Front

What processes change limestone into marble?

Back

Heat and pressure are the processes that change limestone, a sedimentary rock, into marble, a metamorphic rock.

Front

What is acid rain and its effect on rocks?

Back

Acid rain is precipitation that contains acidic components, which can lead to chemical weathering of rocks, especially limestone and marble.

Front

What type of rock is formed from molten magma?

Back

Igneous rock is formed from the cooling and solidification of molten magma.

Front

What type of rock is formed from the alteration of existing rocks due to heat and pressure?

Back

Metamorphic rock is formed from the alteration of existing rocks through heat and pressure.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition, often caused by natural forces like wind, water, and animal actions.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water, acids, or other chemicals.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

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 the difference between igneous and sedimentary rocks?

Back

Igneous rocks are formed from cooled magma or lava, while sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles.
