Earth Science: Weathering, Erosion, Deposition and Landforms

Front

What is weathering?

Back

The process of breaking down rocks and minerals into smaller pieces by physical, chemical, or biological means.

Front

What is erosion?

Back

The process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is deposition?

Back

The process in which sediments, soil, and rocks are added to a landform or land mass, often occurring when the transporting medium loses energy.

Front

What is the difference between physical and chemical weathering?

Back

Physical weathering involves the mechanical breakdown of rocks without changing their chemical composition, while chemical weathering involves changes in the chemical structure of minerals.

Front

What are dunes?

Back

Dunes are hills of sand formed by the wind, often found in deserts and along coastlines.

Front

What is a moraine?

Back

A moraine is a landform made of glacial debris, consisting of rocks and sediment deposited by a glacier.

Front

What is a stalagmite?

Back

A stalagmite is a mineral formation that rises from the floor of a cave, formed by the dripping of mineral-rich water.

Front

What is a stalactite?

Back

A stalactite is a mineral formation that hangs from the ceiling of a cave, formed by the dripping of mineral-rich water.

Front

What factors influence the rate of erosion?

Back

Factors include the type of material being eroded, the speed of the transporting medium (water, wind), vegetation cover, and human activities.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living organisms, often transported by water, wind, or ice.
