Weathering and Erosion

Front

What is the definition of weathering?

Back

The process of breaking down rocks and minerals into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

The movement of weathered rocks and sediments from one location to another by natural forces such as water, wind, or ice.

Front

What is deposition?

Back

The dropping off of sediments in a new location after being transported by erosion.

Front

How does erosion affect the landscape?

Back

Erosion can reshape the landscape by removing soil and rock, leading to the formation of valleys, cliffs, and other landforms.

Front

What are some natural forces that cause erosion?

Back

Water (rivers, rain, waves), wind, and ice (glaciers) are natural forces that cause erosion.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those weathered materials.

Front

What role does gravity play in erosion?

Back

Gravity pulls materials downhill, contributing to processes like landslides and the flow of rivers.

Front

What is a landform created by deposition?

Back

Deltas, beaches, and sandbars are examples of landforms created by deposition.

Front

How can human activities influence erosion?

Back

Human activities such as deforestation, construction, and agriculture can increase erosion by disturbing the soil and vegetation.

Front

What is the impact of climate on weathering and erosion?

Back

Climate affects the rate of weathering and erosion; for example, wet climates can enhance chemical weathering, while dry climates may lead to physical weathering.
