What is chemical weathering?

Back

Chemical weathering is the process by which rocks are broken down by chemical reactions, often involving water, acids, or gases, leading to changes in the mineral composition of the rocks.

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition, often due to temperature changes, freeze-thaw cycles, or mechanical forces.

Front

What is erosion?

Back

Erosion is 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

Deposition is the process in which sediment settles out of the water or wind that is carrying it, leading to the accumulation of material in a new location.

Front

What causes the greatest amount of erosion on beaches?

Back

Waves cause the greatest amount of erosion on beaches by constantly crashing against the shore and removing sand and sediment.

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller particles through physical, chemical, or biological means.

Front

What is sedimentation?

Back

Sedimentation is the process by which particles settle out of a fluid (like water or air) and accumulate as sediment.

Front

What role do glaciers play in erosion?

Back

Glaciers erode the landscape by scraping and grinding rocks as they move, transporting large amounts of sediment.

Front

How does wind contribute to erosion?

Back

Wind contributes to erosion by lifting and carrying small particles of soil and sand, especially in dry and arid regions.

Front

What is the relationship between weathering and soil formation?

Back

Weathering is essential for soil formation as it breaks down rocks into smaller particles that mix with organic material to create soil.
