Weathering and Erosion Review

What is physical weathering?

• The biological actions of living things breaking down rocks

• The change in a rock's composition due to chemical reactions

• Physical forces that break rock into smaller pieces called sediments

• The movement of eroded materials from one place to another

Which of the following is NOT a type of physical weathering?

• Temperature changes causing expansion and contraction of rocks

• Abrasion from rocks and sediment grinding against each other

• Plants' roots growing into cracks in rocks

• Oxygen combining with minerals to create oxides

What is frost wedging?

• When water gets into cracks of a rock and freezes, causing expansion

• When rocks are broken down by the impact of falling water

• When plants' roots grow into rock cracks and break the rock apart

• When rocks are smoothed by wind or water

Which of the following is the result of chemical weathering?

• The biological actions of animals burrowing into rocks

• The physical breaking apart of rocks into smaller pieces

• The change in a rock's composition (shape or color) from a substance

• The transportation of sediment by wind or water

Which process is involved in hydration as a form of chemical weathering?

• Water freezing and expanding in rock cracks

• Water reacting with minerals to form substances like clay

• Water transporting sediments to new locations

• Water eroding rock surfaces by physical force

What are landforms?

• Substances that react with rocks during chemical weathering

• The surface on top of the earth, not created by humans, that look the way they do because of weathering, erosion, and deposition

• The biological organisms that contribute to the weathering of rocks

• The chemical compounds formed during oxidation

What is erosion?

• The process of soil and rock being deposited in new locations

• The movement of small pieces of landforms to different locations by ice, water, wind, or gravity

• The destruction of land due to human activities

• The process of water evaporating from the earth's surface

What can vegetation act as to prevent soil from washing away?

• A nutrient provider

• A barrier against erosion

• A source of erosion

• A water absorber

What is a natural hazard?

• A man-made event causing minimal damage to the environment

• A natural phenomenon that has positive effects on wildlife

• A natural phenomenon that can have negative effects on humans, animals, or the environment

• A predictable event that occurs regularly without causing any damage
