Changes in Landscapes Over Time

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the movement of weathered materials from one place to another, often caused by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments, soil, and rocks are added to a landform or land mass, often after being transported by erosion.

Front

Which layer of soil is typically the oldest?

Back

The bottom layer of soil is usually the oldest because it has been there the longest.

Front

What is a landslide?

Back

A landslide is the sudden movement of rock and soil down a slope, often caused by gravity.

Front

How do waves contribute to landscape changes?

Back

Waves can erode coastlines and deposit sand and shells on beaches, changing the landscape over time.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away from their original location.

Front

What natural forces can cause weathering?

Back

Natural forces that cause weathering include wind, water, ice, and temperature changes.

Front

What is the role of gravity in landscape changes?

Back

Gravity causes materials to move downhill, leading to processes like landslides and erosion.

Front

What is an example of deposition?

Back

An example of deposition is when a river slows down and drops off sand and gravel at its mouth, forming a delta.
