6th - Weathering and Erosion

Mounds of wind-deposited sand in deserts and on shorelines are

• sea arches
• sea stacks
• dunes
• cliffs

Which causes chemical weathering?

• acids and oxygen
• water, wind and gravity
• abrasion
• root and ice wedging

Plants usually break open small cracks in rocks with their

• branches
• pollen

What is weathering?

• occurs when the eroded materials are dropped or laid down

• fragments of weathering rocks

• the process by which rock materials are broken down by the action of physical and chemical process

• the process by which wind, water, ice or gravity transport weathered materials from one location to another
