Rocks & Rock Cycle

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed from the accumulation and compaction of mineral and organic particles, often found at the bottom of lakes, rivers, and oceans.

Front

What is igneous rock?

Back

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

Front

What is metamorphic rock?

Back

Metamorphic rock is formed when existing rocks are subjected to heat and pressure, causing physical and chemical changes.

Front

What are the three major types of rocks?

Back

The three major types of rocks are igneous, sedimentary, and metamorphic.

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 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 the Earth's surface by wind, water, or ice and transported to another location.

Front

What is deposition?

Back

Deposition is the process where sediments settle out of the transporting medium (like water or air) and accumulate in a new location.

Front

What is cementation?

Back

Cementation is the process by which dissolved minerals crystallize and glue particles of sediment together, forming sedimentary rock.

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 reached the Earth's surface.
