Question 12

The cooling of a gas that happens when the gas expands with no way of getting more energy

Answer 12

Adiabatic cooling

Question 13

Small airborne particles upon which water vapor condenses to form clouds

Answer 13

Cloud condensation nuclei

Question 14

What kind of water makes up the majority of earth’s water supply?

Answer 14

saltwater

Question 15

What is the largest source of freshwater on the planet?

Answer 15

glaciers and icebergs

Question 16

What is the largest source of liquid freshwater on the planet?

Answer 16

groundwater

Question 17

In the hydrologic cycle, name the ways water can enter the atmosphere.

Answer 17

evaporation and transpiration

Question 18

When a raindrop hits the ground, name three ways it can eventually end up in a river.

Answer 18

surface runoff
soak into the groundwater and get to the river via groundwater flow
be evaporated before it soaks into the ground, condensed into a cloud, and precipitated into the river

Question 19

What process in the hydrologic cycle puts soil moisture into the atmosphere?

Answer 19

Transpiration

Question 20

In which body of water would the residence time be shorter: a quickly moving river or a lake that
has no river outlets?

Answer 20

The residence time in the river is shorter

Question 21

What must a lake have in order for it to be a freshwater lake?

Answer 21

A lake must have a way to get rid of water other than just evaporation

Question 22

Why is the salinity of the ocean evidence that the earth is not billions of years old?

Answer 22

The oceans are not salty enough for the earth to be billions of years old

Question 23

If you tasted melted sea ice, would it taste like freshwater or saltwater?

Answer 23

Melted sea ice would taste like saltwater

Question 24

Where do icebergs come from?

Answer 24

Icebergs come from glaciers

Question 25

Where do glaciers come from?

Answer 25

Glaciers start on mountains as the result of snow that never completely melts in the summer

Question 26

What is the term for the process by which a portion of a glacier breaks off and falls into the water?

Answer 26

calving

Question 27

The captain of a ship sees an iceberg and steers clear of it. Why is the captain still worried about a collision?

Answer 27

The captain is worried because 90% of the glacier is underwater and therefore not visible

Question 28

Suppose you studied two areas of land close to one another. In the first, there are a lot of trees. In the second, there are almost no trees at all. Other than that, the two areas seem identical. They have the same kind of grass and experience the same weather. Which one has the deeper water table?

Answer 28

The water table will be deeper in the area with lots of trees

Question 29

If no energy is added to air, what happens to the temperature when the air expands?

Answer 29

The air will cool as it expands

Question 30

Will fog be thicker in a smoky area or an area free of smoke?

Answer 30

the fog will be thicker in the smoky area

Question 31

What kind of cooling is responsible for most cloud formation?

Answer 31

adiabatic

Question 32

A bright student notes that with a few modifications, a refrigerator can become a “hot box,” keeping things warm instead of cold. Explain.

Answer 32

If you simply reversed the design so that the pipes carrying the gas after compression are on the inside of the refrigerator, the inside would heat up

Question 33

What kind of water pollution is the hardest to track back to its source?

Answer 33

Groundwater pollution
