Rock Transformations: Chapter 2

Front

What is erosion?

Back

Erosion is the process by which sediment and soil are worn away and transported from one location to another, often by wind, water, or ice.

Front

What is energy?

Back

Energy is the ability to make things move or change. It can exist in various forms, such as kinetic, potential, thermal, and chemical energy.

Front

What process is caused by energy from Earth's interior?

Back

Melting is the process caused by energy from Earth's interior, where solid rock transforms into magma due to high temperatures.

Front

What is compacting and cementing?

Back

Compacting and cementing is the process where sediment is pressed together and glued by minerals, forming sedimentary rock.

Front

True or False: Magma forms when any type of rock is melted, a process driven by energy from Earth’s interior.

Back

True.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural processes such as wind, water, and temperature changes.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken pieces from one place to another.

Front

What role does gravity play in erosion?

Back

Gravity helps to pull sediment downhill, contributing to erosion, especially in landslides and riverbanks.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things, often transported by water, wind, or ice.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation, involving igneous, sedimentary, and metamorphic rocks.
