Weathering and Erosion

What is the core difference between weathering and erosion?

• Weathering moves rocks, while erosion breaks them down

• Weathering breaks down rocks, while erosion transports the fragments

• Both occur simultaneously with no functional difference

• Erosion happens underground, while weathering occurs on the surface

Which process describes frost wedging?

• Chemical reaction creating rust in rocks

• Plant roots growing through rock fissures

• Wind carrying sand that scrapes rock surfaces

• Water freezing in cracks and expanding to fragment rock

Which statement about abrasion is true?

• It's a chemical process involving oxygen

• It requires biological agents like plants

• It involves mechanical scraping by wind/water/ice

• It occurs exclusively in glacial environments

Which of the following is NOT a primary agent of erosion?

• water

• wind

• ice

• fire

How does wind act as an agent of erosion?

• By carrying and transporting small particles from one place to another

• By dissolving rocks through chemical reactions

• By freezing and expanding in rock cracks

• By causing earthquakes

Which factor can increase the rate of weathering in rocks?

• Lack of vegetation

• Absence of water

• Presence of water and higher temperatures

• Low temperatures and dry conditions
