Rocks and Rock Cycle

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, driven by geological processes such as weathering, erosion, and heat.

Front

What type of rock is formed from cooling and solidification of magma?

Back

Igneous rock.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces such as wind, water, and temperature changes.

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 type of rock is formed from the accumulation and compaction of sediment?

Back

Sedimentary rock.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed when existing rocks are changed by heat, pressure, or chemically active fluids.

Front

What is the role of heat and pressure in the rock cycle?

Back

Heat and pressure can transform existing rocks into metamorphic rocks, altering their mineral composition and structure.

Front

What is the difference between igneous and sedimentary rocks?

Back

Igneous rocks form from the cooling of magma, while sedimentary rocks form from the accumulation and compaction of sediments.

Front

What is compaction in the context of sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume and leading to the formation of sedimentary rock.

Front

What is the significance of the opal extraction process?

Back

The opal extraction process can lead to environmental impacts, such as damage to local vegetation and displacement of animals.
