Water Resources 1

Question 1

What are readily accessible waters?

Answer 1

Rivers
Lakes
Living beings
- makes uno a very small part of the fresh water

Question 2

What is the hydrological cycle?

Answer 2

Water evaporates, cools and denses, the precipitates back into the ground

Question 3

What is surface water?

Answer 3

Precipitation that doesn’t do into the ground and isn’t lost to evaporation

Question 4

The land layout determines what?

Answer 4

Which basin the water drains out from

Question 5

What is ground water

Answer 5

Water that gets into the the ground

Question 6

What is an unconfined aquifer?

Answer 6

Only one permeable layer surrounding the wate

Question 7

What is a confined aquifer?

Answer 7

Impermeable layers above and below the aquifer

Question 8

What is an artisanal well?

Answer 8

When you tap into the confined aquifer

- water is under pressure and doesn’t need to be pumped up

Question 9

What does it mean that water is deemed renewable?

Answer 9

Comes back to the earth as precipitation

- 7% of fresh water

Question 10

What does it mean if water is deemed non-renewable?

Answer 10

Comes from melting of ancient glaciers

-20%

Question 11

Is precipitation limited to where it can fall?

Answer 11

No, it can fall anywhere

- can influence the ground

Question 12

Where does she water get used?

Answer 12

Community
Power plants
Agriculture

Question 13

For the public sector, what does most of the water go towards too?

Answer 13

Showers and hygiene

Question 14

What is a water footprint?

Answer 14

Measures our appropriation of fresh water in volumes of water consumed and or polluted

Question 15

What is a blue footprint?

Answer 15

Appropriation of surface and ground water

Question 16

What is a green footprint?

Answer 16

Soil moisture

Appropriation of water stored in soils

Question 17

What is a grey footprint?

Answer 17

Amount of water it’s going to take to handle a good or service is going to pollute

Question 18

Why do Canadians think we don’t have to be water conscious?

Answer 18

We feel like we have a lot of water

Question 19

What are some forms of water security?

Answer 19

Drought
Desertification
Water stress

Question 20

What is one way, that is currently used, to deal with water stress?

Answer 20

Building damns to catch rain and snow and slowly release it into the dry environments
- also used for hydroelectric

Question 21

What are water transfers used for?

Answer 21

Transfer water via pipes from water rich areas to water stressed areas

Question 22

What’s one downfall to water transfers?

Answer 22

Altering the path of the water

-it would never have gone there if we didn’t move it

Question 23

How can aquifers become contaminated?

Answer 23

By pumping aquifers near costal areas, it can fill back in with salt water therefore contaminating it

Question 24

What is subsidence?

Answer 24

When extracting ground water the area can stay where it is or it can shrink

Question 25

What is distillation?

Answer 25

Boiling water so it evaporates and condenses and you get fresh water out of it

Question 26

From distillation, why can’t we dump the salt into the ocean?

Answer 26

Because marine ecosystems are very sensitive to salt concentrations
- can’t put it in the soil either because it will dry up

Question 27

What is cloud seeding?

Answer 27

Waiting for storms to naturally occur so we can increase the number of nuclei that can seed rain or snowflakes

Question 28

What do nuclei chemicals do?

Answer 28

Maximize the amount of precipitation that can come down

Question 29

Why isn’t most of the fresh readily available?

Answer 29

Because it is trapped in ice caps and ground water
