Rock Cycle

Front

What is an Igneous Rock?

Back

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

Front

What is a Sedimentary Rock?

Back

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

Front

What is a Metamorphic Rock?

Back

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

Front

What process forms Igneous Rocks?

Back

Igneous rocks form through the cooling and solidification of magma or lava.

Front

What is the role of weathering and erosion in the rock cycle?

Back

Weathering breaks down rocks into smaller pieces, and erosion transports these pieces to new locations, where they can form sedimentary rocks.

Front

What is the process of melting in the rock cycle?

Back

Melting occurs when rocks are subjected to high temperatures, turning solid rock into magma.

Front

What is the significance of heat and pressure in the formation of Metamorphic Rocks?

Back

Heat and pressure cause changes in the mineral composition and structure of existing rocks, leading to the formation of metamorphic rocks.

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 surface.

Front

What is sediment?

Back

Sediment consists of small particles of rock, minerals, and organic material that accumulate over time, often forming sedimentary rocks.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process where rocks are formed, broken down, and reformed through geological processes.
