Unit 4 Earth's Changing Surface Review 2024

Front

What does it mean when something is described as 'intact'?

Back

It means that the object or structure is undamaged and preserved in its original state.

Front

What is deposition in the context of a river?

Back

Deposition is the process by which sediment is laid down in new locations, often occurring when a river slows down as it enters a larger body of water.

Front

What is the Pacific Ring of Fire?

Back

It is a region in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur due to tectonic plate movements.

Front

How does wind erosion shape the landscape?

Back

Wind erosion can create unique geological structures such as hoodoos, arches, and sand dunes by wearing away rock and soil.

Front

What are constructive geologic processes?

Back

Constructive geologic processes are natural processes that build up the Earth's surface, such as sedimentation and delta formation.

Front

What is sedimentation?

Back

Sedimentation is the process of settling or being deposited as sediment, often in bodies of water.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river, where it meets a body of water, characterized by sediment deposition.

Front

What causes volcanic eruptions?

Back

Volcanic eruptions are caused by the movement of tectonic plates, which can lead to the buildup of pressure and the release of magma.

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 wind, water, and ice.

Front

What is the role of tectonic plates in Earth's geology?

Back

Tectonic plates are large sections of the Earth's crust that move and interact, causing earthquakes, volcanic activity, and the formation of mountains.
