Constructive and Destructive Forces Flashcard Review

Front

What are constructive forces?

Back

Constructive forces are natural processes that build up landforms, such as mountains and islands, by adding material to the Earth's surface.

Front

What are destructive forces?

Back

Destructive forces are natural processes that break down landforms, such as erosion and weathering, which remove material from the Earth's surface.

Front

How do volcanoes act as constructive forces?

Back

Volcanoes create new landforms, like islands, by erupting lava that cools and solidifies.

Front

How do volcanoes act as destructive forces?

Back

Volcanoes can destroy land and vegetation through lava flows and ash deposits during eruptions.

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 wind, water, or ice.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces through processes like freezing, thawing, and chemical reactions.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often leading to their breakdown.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often at the mouth of rivers.

Front

How are mountains formed?

Back

Mountains are typically formed by constructive processes such as tectonic plate movements that push land upward.
