What is coastal erosion?

Back

Coastal erosion is the process by which waves and currents wear away the land along the coastline, leading to the loss of soil and rock.

Front

How do waves contribute to coastal erosion?

Back

Waves pound against rocks and soil, breaking them down into sand and moving the coastline further inward.

Front

What are tectonic plate boundaries?

Back

Tectonic plate boundaries are the edges where two tectonic plates meet, often associated with geological activity such as earthquakes and volcanic eruptions.

Front

What triggers a tsunami?

Back

A tsunami is triggered by sudden displacements of water caused by events like earthquakes, landslides, or volcanic eruptions.

Front

What role does gravity play in the formation of a tsunami?

Back

Gravity acts to restore balance to the displaced water, causing waves to travel across the ocean, resulting in a tsunami.

Front

What is deposition in a river system?

Back

Deposition is the process where sediment carried by the river is dropped or settled, often occurring at lower elevations or slower-moving water.

Front

Where does the greatest amount of deposition occur in a river?

Back

The greatest amount of deposition typically occurs at the mouth of the river, where it meets a larger body of water.

Front

What is an oxbow lake?

Back

An oxbow lake is a crescent-shaped lake formed when a meandering river cuts off a bend, leaving behind a stagnant body of water.

Front

How does a river meander?

Back

A river meanders as it flows, creating curves due to erosion on the outer banks and deposition on the inner banks.

Front

What is the process of erosion?

Back

Erosion is the process by which natural forces like water, wind, or ice wear away rocks and soil.
