Major processes we've discussed

Weathering, Erosion, and Deposition

Let's start by reviewing the differences between these

Multiple Choice

The process by which rocks and other material are broken down on Earth's surface is called ____________.

• erosion

• deposition

• transfering

• weathering

Multiple Choice

The process in which these particles are moved from one location to another is called __________.

• erosion

• deposition

• abrasion

• weathering

Multiple Choice

The process by which particles are deposited in a new location is called ____________.

• erosion

• weathering

• deposition

• ice wedging

Multiple Choice

Which of the following is the stronger acid?

• Carbonic acid

• Sulfuric acid

Multiple Choice

Easter Island has a tropical rainforest climate, which means it is wet with lots of rainfall. What effect would the climate have on the weathering of its stone statues?

• It would speed up the rate of weathering.

• It would slow down the rate of weathering.

• It would stop the weathering.

Multiple Choice

Weathering is generally a __________ process. It can affect anything exposed to the _________.

• Fast, ocean

• Slow, ocean

• Fast, atmosphere

• Slow, atmosphere

Multiple Choice

Pressure, changes in temperature, ice wedging, organic activity, and abrasion all cause _______ weathering.

• mechanical

• compresses

• expands

• chemical

Multiple Choice

When pressure is relieved from a rock, the rock ______ causing fractures in the rock, eventually ______ of rock will peel away.

• compresses, blocks

• expands, blocks

• compresses, sheets

• expands, sheets

Multiple Select

What are some factors that affect the rate of weathering? Select all that apply.

• the exposed surface area of the rock

• the mass of the rock

• the composition of the rock

• the climate

• the color of the rock

Multiple Choice

Which would weather faster, a large solid boulder, or a boulder cut into pieces?

• the cut boulder because it has a smaller surface area

• the large boulder because it has a larger surface area

• the cut boulder because it has a larger surface area

• the large boulder because it has a smaller surface area

Multiple Choice

An icicle shaped mineral deposit hanging from the ceiling of a cavern.

• stalagmite

• stalactite

• ice wedging

• quartz

Multiple Choice

What are deserts, plowed fields, and beach areas often affected by?

• wind erosion

• runoff deposition

• glacier erosion

• glacier depostion

Multiple Choice

As a glacier flows along a narrow valley, it abrades its sides forming a ______.

• sand bar

• U-shaped valley

• delta

• cavern

Ice age

An ice age is a geologic period of time during which the temperature of Earth’s surface and atmosphere is reduced drastically. This results in the formation of thick ice sheets and glaciers that expand to cover vast areas of land. This period of time can take millions of years and cause a drastic change in the shape of continents. 

The causes of ice ages are not fully understood. Yet, scientists believe that important factors such as the atmospheric composition, changes in Earth’s orbit around the sun, and position of the continents at that time are all responsible for triggering ice ages. 

Glaciers from the ice age cause erosion and deposition, which resulted in unique features such as glacial horns, lakes, U-shaped valleys, and moraines.

Multiple Select

Which of the following are used to prevent erosion? Select all that apply.

• sea wall

• windbreaks

• sand bar

• larger rocks

• jetties
