Weathering Quiz

What is weathering?

• The process of cleaning rock on Earth's surface

• The process of breaking down rock on Earth's surface

• The process of transporting rock on Earth's surface

• The process of hardening rock on Earth's surface

What are the two types of weathering?

• Physical and Biological

• Mechanical and Chemical

• Internal and External

• Erosion and Deposition

What does mechanical weathering involve?

• The process in which rock is chemically broken into smaller pieces

• The process in which rock is physically broken into smaller pieces

• The process in which rock is melted into smaller pieces

• The process in which rock is dissolved into smaller pieces

How does chemical weathering break down rock?

• Through physical changes

• Through chemical changes

• Through biological changes

• Through temperature changes

What is one of the results of rocks being broken down into smaller pieces?

• Creation of mountains

• Creation of rivers

• Creation of soil

• Creation of diamonds

What is the process called when water seeps into the cracks of rocks, freezes, and expands to break the rocks apart?

• Root Wedging

• Salt Wedging

• Frost Wedging

• Thermal Expansion

Which type of mechanical weathering occurs when plant roots grow larger in the cracks of rocks and eventually break the rocks apart?

• Abrasion

• Exfoliation

• Frost Wedging

• Root Wedging

What happens during salt wedging?

• Rocks are broken down by moving particles carried by wind, water, ice, or gravity

• Outer layers of rocks weather and peel off in thin sheets

• Water seeps into the cracks of rocks and evaporates leaving salt behind, which forms salt crystals that break rocks apart

• The heating and cooling of rocks due to environmental conditions causes rocks to break over time

What is abrasion in the context of mechanical weathering?

• The heating and cooling of rocks due to environmental conditions

• The process where rocks are broken down by moving particles carried by wind, water, ice, or gravity

• The growth of plant roots in the cracks of rocks

• The formation of salt crystals in the cracks of rocks

What is exfoliation in geological terms?

• The process of rocks breaking down due to plant root growth

• The peeling off of outer layers of rocks in thin sheets due to weathering

• The breaking of rocks by the formation of ice in their cracks

• The breaking of rocks due to the expansion and contraction caused by temperature changes
