Weathering, erosion, deposition

Question 1

vocab: evaporation

Answer 1

Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure.

Question 2

vocab:condensation

Answer 2

Condensation is the process by which water vapor in the air is changed into liquid water. In other words, the water in the air, a gas known as water vapor, from your hot shower cooled when it met the surface of the cold mirror. This caused the water vapor to condense, or turn into its liquid form.

Question 3

vocab: precipitation

Answer 3

Precipitation is any type of water that forms in the Earth’s atmosphere and then drops onto the surface of the Earth. Water vapor, droplets of water suspended in the air, builds up in the Earth’s atmosphere before precipitating.

Question 4

What is the relationship between surface area and weathering rate?

Answer 4

Rocks that have a large surface area exposed to running water, wind and other weathering agents will erode more quickly than rocks with less exposed surface area.

Question 5

How do rivers and glaciers affect the shape of valleys?

Answer 5

V-shaped valleys and river plain valleys are formed by flowing water. U-shaped valleys are formed by flowing ice, or glaciers. ..

Question 6

What agent of erosion causes the most change on the earth’s surface?

Answer 6

?Ice is most powerful. Water? Wind?

Question 7

what climate favors mechanical weathering and chemical weathering?

Answer 7

Mechanical weathering occurs more in hot, wet. climates. Chemical weathering also occurs in area of high temperatures and greater rainfall.

Question 8

What are the % of freshwater and saltwater on Earth doing?

Answer 8

?

Question 9

identify if an example describes weathering, erosion or deposition

Answer 9

Look at examples in your book or online and identify each of the processes.

Question 10

Vocab: mechanical weathering

Answer 10

The process through which large rocks are broken into smaller rocks by a process. Water freezing and thawing is an example.

Question 11

Vocab: Chemical weathering

Answer 11

Rocks are broken down by chemical processes such as reactions between chemicals in the rock and water, the rock being oxidizes, i.e., the chemicals in the rock interact with oxygen in the air.

Question 12

vocab: erosion

Answer 12

The process by which the surface of the earth is worn away by actions of water, glaciers, winds, chemical reactions.

Question 13

vocab: deposition

Answer 13

Sediments, soil and rocks are added to a landform or landmass.

Question 14

vocab: Oxbow Lake

Answer 14

An oxbow lake is a U-shaped lake that forms when a wide meander of a river is cut off, creating a free-standing body of water.

Question 15

vocab: Mass wasting

Answer 15

Mass wasting or mass movement is the movement of a large mass of rock, soil and debris downward due to the pull of gravity, e.g., a mud slide.

Question 16

vocab: Meander

Answer 16

S Large curves, called meanders, form because of erosion and deposition by the moving water. The curves are called meanders because they slowly “wander,” or meander, over the land. Below, you can see how this happens (Figure below). See picture: https://www.ck12.org/earth-science/erosion-by-streams/lesson/Erosion-by-Streams-MS-ES/
