Constructive and Destructive Forces

Front

What is a constructive force?

Back

A constructive force is a natural process that builds up landforms, such as mountains and valleys, by adding material to the Earth's surface.

Front

What is a destructive force?

Back

A destructive force is a natural process that breaks down landforms and erodes the Earth's surface, such as through weathering, erosion, and earthquakes.

What does a seismograph measure?

Back

A seismograph measures the strength of an earthquake.

Front

How do tectonic plates create mountains?

Back

Tectonic plates push together, forcing one plate under the other and pushing the land upward, creating mountains.

Front

What is a sea arch?

Back

A sea arch is a natural rock formation created by the erosion of waves, often found along coastlines.

Front

How do waves act as destructive forces?

Back

Waves can wear away at the Earth's coast over time, changing its shape and creating features like sea arches.

Front

What is the primary purpose of a dam?

Back

The primary purpose of a dam is to control floodwaters and store water for people to use.

Front

How can plants contribute to the weathering of rocks?

Back

Plants can cause weathering by having roots grow into or near rocks, which can break down the rocks over time.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as water, wind, or ice.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural processes, including physical and chemical changes.
