ES 8 Weathering and Erosion Review

The breaking of rocks into smaller pieces, known as sediment, is called -

• Weathering

• Erosion

• Karst Topography

• Zone of Aeration

• Bedrock

Which type of weathering is defined as the physical breakdown of rocks into smaller pieces, without changing their chemical composition?

• Mechanical Weathering

• Chemical Weathering

• Karst Topography

• Bedrock

• The Law of Superposition

Which type of weathering involves water seeping into the cracks of rocks and expanding due to extremely cold temperatures, causing larger cracks in the rock?

• Frost Wedging

• Hydraulic Abrasion

• Wind Abrasion

• Root Wedging

• Exfoliation

Which type of physical weathering would be responsible for the rock formation shown in the diagram?

• Wind Abrasion

• Frost Wedging

• Root Wedging

• Exfoliation

• Oxidation

Look at these rocks. Aren't they beautiful? They are smooth, as smooth as Mr. Lilley's slick dance moves. I'm not saying he's good, but he taught Dougie, how to Dougie. Anyways, how did these rocks most likely get so smooth?

• Water got into the cracks of the rocks and froze solid

• Water in a river moved over the rocks, slowly breaking the rock down and smoothing the rock

• Water dissolved the rock and created a sinkhole

• A plant developed roots in the rock which broken down the rock into smaller pieces

• An animal ate the rock and their digestive system slowly smoothed over the rock after a period of several years

Which of the following are examples of mechanical weathering? (Choose all that apply)

• Exfoliation

• Oxidation

• Abrasion

• Acid Rain

• Root Wedging

Answer explanation

Mechanical weathering is when rocks break down due to physical force

Which of the following types of mechanical weathering involves the uplift of rocks, resulting in the expansion of the rock and the top most layers of rock breaking off into sheets?

• Exfoliation

• Abrasion

• Root Wedging

• Animal Damage

• Frost Wedging

Which of the following are examples of chemical weathering? (Choose all that apply)

• Exfoliation

• Oxidation

• Abrasion

• Acid Rain

• Root Wedging

Answer explanation

Oxidation is when water reacts with metal to create rust

Which type of weathering is defined as the breakdown of rocks into smaller pieces, by changing the minerals into different substances and changing their composition?

• Mechanical Weathering

• Chemical Weathering

• Karst Topography

• Bedrock

• The Law of Superposition

Limestone rocks are typically dissolved by weak carbonic acid which is made when carbon dioxide in the atmosphere mixes with precipitation. We more commonly call this -

• Acid Rain

• The Doritos Locos Tacos at Taco Bell

• Calcium Carbonate Stones

• Abrasion

• Exfoliation
