Rock Transformations Review

Front

What is igneous rock?

Back

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

Front

How can sedimentary rock transform into igneous rock?

Back

Sedimentary rock can transform into igneous rock if it is buried deep within the Earth, where it is subjected to high temperatures and pressures, causing it to melt into magma.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed when existing rocks (igneous, sedimentary, or other metamorphic rocks) are subjected to heat and pressure, causing physical and chemical changes.

Front

How does gneiss form?

Back

Gneiss forms from the metamorphism of granite or sedimentary rocks under high temperature and pressure.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various geological processes, including melting, cooling, erosion, and sedimentation.

Front

What role does weathering play in rock transformation?

Back

Weathering breaks down rocks into smaller pieces, which can then be transported and eventually form sedimentary rock.

Front

What is the difference between magma and lava?

Back

Magma is molten rock beneath the Earth's surface, while lava is magma that has reached the Earth's surface.

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form from the accumulation and compaction of mineral and organic particles, often in layers.

Front

What is the process of 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 the significance of plate tectonics in rock formation?

Back

Plate tectonics explains the movement of Earth's plates, which can lead to the formation of mountains, earthquakes, and volcanic activity, all of which contribute to rock transformation.
