Weathering and Erosion 2

Front

What is weathering?

Back

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

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by wind, water, or ice and transported to another location.

Front

What is abrasion in the context of weathering?

Back

The grinding away of rock surfaces through mechanical action, often caused by the movement of water, wind, or ice.

Front

What role does water play in erosion?

Back

Water can transport sediments and erode landscapes through processes like river flow, rainfall, and ocean waves.

Front

What is deposition?

Back

The process by which sediments, soil, and rocks are added to a landform or land mass, often occurring in areas where the energy of the transporting medium decreases.

Front

How do glaciers contribute to erosion?

Back

Glaciers erode the landscape by scraping and grinding rocks beneath them, transporting debris as they move.

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 minerals of the rocks due to chemical reactions.

Front

What is the primary cause of soil formation?

Back

Soil is primarily formed through the physical and chemical weathering of rocks, along with the accumulation of organic matter.

Front

How do sand dunes form?

Back

Sand dunes form primarily through the deposition of sand by wind, which shapes the sand into mounds.

Front

What is the impact of fast-moving water on rocks?

Back

Fast-moving water can quickly break rocks into smaller particles or sand through erosion.
