Rocks and Rock Cycle Activity

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 igneous, sedimentary, and metamorphic formations.

Front

What are igneous rocks?

Back

Igneous rocks are formed from the cooling and solidification of magma or lava. Examples include granite and basalt.

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles. Examples include sandstone and limestone.

Front

What are metamorphic rocks?

Back

Metamorphic rocks are formed from existing rocks that are changed by heat, pressure, or chemically active fluids. Examples include schist and marble.

Front

What process leads to the formation of sedimentary rocks?

Back

Sedimentary rocks are formed through processes such as weathering, erosion, deposition, compaction, and cementation.

Front

How do fossils form in rocks?

Back

Fossils form when organisms are buried by sediment, which then compacts and hardens into rock, preserving the shape of the organism.

Front

What is the difference between magma and lava?

Back

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

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 weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through physical, chemical, or biological means.

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.
