Rocks & Rock Cycle

The Rock Cycle is the continuous process of rock changing from one type to another, involving processes like melting, cooling, erosion, and sedimentation.

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

Metamorphic rock is formed from the heating and compression of another type of rock over time.

Extrusive igneous rock is formed from the cooling of volcanic ash on Earth's surface.

Erosion is the process that breaks down rocks and transports sediments, playing a crucial role in the rock cycle.

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

Sedimentary rocks are formed from the accumulation and compaction of sediments, often containing fossils.

Metamorphic rocks are formed from existing rocks that have been changed by heat, pressure, or chemically.

Intrusive igneous rocks form from magma cooling slowly beneath the Earth's surface, while extrusive igneous rocks form from lava cooling quickly on the surface.

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