LWH Erosion & Deposition Practice

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow, and transported to another location.

Front

What is deposition?

Back

Deposition is the geological process in which sediments, soil, and rocks are added to a landform or land mass, often occurring when the transporting medium (like water or wind) loses energy.

Front

What causes the deposition of sand at a delta?

Back

The deposition of sand at a delta is primarily caused by river water slowing as it enters the ocean, leading to a loss of energy and the dropping of sediment.

Front

What is weathering?

Back

Weathering is the breakdown of rocks and minerals into smaller particles through physical, chemical, or biological processes.

Front

How does weathering relate to erosion?

Back

Weathering provides the sediment that erosion transports; without weathering, there would be no material for erosion to move.

Front

What is a mudslide?

Back

A mudslide is a rapid flow of mud down a slope, often triggered by heavy rainfall or the destabilization of soil, which can deposit sediment on structures below.

Front

What is a delta?

Back

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

Front

What is a topographical map?

Back

A topographical map is a detailed and accurate graphic representation of cultural and natural features on the ground, showing elevation changes and landforms.

Front

What is a mountain?

Back

A mountain is a large landform that rises prominently above its surroundings, typically characterized by steep slopes and significant elevation.

Front

What is the role of ocean waves in sediment transport?

Back

Ocean waves can transport sand and sediment toward land, contributing to coastal erosion and deposition processes.
