Weathering/Erosion/Deposition

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.

What is mechanical weathering?

Back

Mechanical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition, often through physical forces like freezing and thawing.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, leading to the breakdown of the rock structure, often due to reactions with water, acids, or gases.

Front

What is deposition?

Back

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

How do mudslides relate to erosion?

Back

Mudslides are a type of erosion where saturated soil and debris flow down a slope, removing material from one area and depositing it in another.

What role do rivers play in erosion?

Back

Rivers erode the land by carrying away soil and rocks as they flow, shaping the landscape and creating features like valleys and canyons.

What is an example of mechanical weathering?

Back

An example of mechanical weathering is rocks being smoothed by tumbling across a stream bed, where physical forces wear down the rock surfaces.

Front

How do waves contribute to deposition?

Back

Waves contribute to deposition by dropping sand and other materials on the beach as they lose energy when they reach the shore.

What is the difference between erosion and deposition?

Back

Erosion involves the removal and transport of materials, while deposition is the process of laying down those materials in a new location.

What natural forces can cause erosion?

Back

Natural forces that can cause erosion include water (rivers, rain), wind, ice (glaciers), and gravity.
