Fast-moving water can exert _______ on rocks, leading to their fragmentation.

• pressure

• heat

• light

• sound

Water can dissolve minerals, facilitating (a)   weathering.

• chemical
• physical

Wind velocity can aid in which of the following? Check ALL that apply.

• chemical weathering

• physical weathering

• biological weathering

• sedimentary weathering

Which of the following factors affect weathering? Check all that apply.

• ice

• water velocity

• lithification

• temperature

• wind velocity

Match the types of weathering with the correct definition.

• frost-wedging

• Water freezes in rock cracks, expanding and causing fragmentation-wedging

• thermal expansion

• Temperature changes cause rocks to expand and contract, leading to cracks.

• abrasion

• Rocks and sediments grind against each other, wearing down surfaces

Match the types of weathering with the correct definition.

• carbonation

• Reaction with water that alters minerals

• oxidation

• Reaction with carbon dioxide to form carbonic acid

• hydrolysis

• Reaction with oxygen, often affecting iron-bearing minerals (formation of rust)

Which type of weathering involves the change in composition and structure?

• Chemical Weathering

• Physical Weathering
