Unit 4 Earth's Changing Surface Review 2024

Front

What are the two types of forces that volcanoes represent?

Back

Destructive and constructive forces.

Front

What triggers a tsunami?

Back

An earthquake, landslide, or volcano that causes a large part of the water surface to rise or fall.

Front

What is the role of gravity in the formation of tsunamis?

Back

Gravity acts to balance the water levels after a sudden displacement, resulting in a tsunami.

Front

What are the four main agents of erosion?

Back

Gravity, Ice, Wind, and Water.

Front

What does the eruption of Mount Vesuvius teach us about volcanic eruptions?

Back

It can bury towns and preserve them intact for future study.

Front

What is Freeze Thaw Erosion?

Back

It occurs when water seeps into cracks, freezes, expands, and eventually breaks the rock apart.

Front

How do volcanoes create new land?

Back

By erupting lava that cools and solidifies, forming new islands.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken materials.

Front

What is an example of a constructive force in nature?

Back

Volcanic eruptions that create new landforms.

Front

What is the impact of gravity on erosion?

Back

Gravity pulls materials down slopes, contributing to erosion.
