Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces or sediments through physical, chemical, or biological means.

Front

What causes physical weathering?

Back

Physical weathering is caused by natural forces such as water freezing and thawing, temperature changes, and wind.

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 water, wind, or ice.

Front

How does water contribute to weathering?

Back

Water can enter cracks in rocks, freeze, expand, and cause the rock to break apart over time.

Front

What is sediment?

Back

Sediment is small particles of rock, minerals, or organic material that have been broken down by weathering.

Front

What is a canyon?

Back

A canyon is a deep valley with steep sides, often formed by the erosion of rock by a river over a long period.

Front

What role does rapidly moving water play in landform creation?

Back

Rapidly moving water can erode rock and soil, leading to the formation of canyons and valleys.

Front

What is a volcanic eruption?

Back

A volcanic eruption is a rapid change to Earth's surface where molten rock, ash, and gases are expelled from a volcano.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials to new locations.

Front

What is a landslide?

Back

A landslide is a rapid movement of rock and soil down a slope, often triggered by heavy rain or earthquakes.
