Question 6

What is the troposphere?

Answer 6

• It’s the first layer of the earth
• It contains most of the water vapor
• And is where global warming occurs

Question 7

What is the statosphere?

Answer 7

• It’s the second layer
• The ozone layer is found there

Question 8

What’s the mesosphere?

Answer 8

• It’s the third layer
• The air density, air pressure, and temp decreases with altitude
• It’s the coldest layer

Question 9

What’s the thermosphere?

Answer 9

• It’s the fourth layer
• The temp increases with altitude
• Radiation from the sun removes electrones from oxygen and nitrogen atoms forming ions

Question 10

What’s throughflow?

Answer 10

It’s the sporadic horizontal flow of water within the soil layer

Question 11

What’s Interception?

Answer 11

It’s when the water coming from percipitation is trapped by tree canopies and buildings

Question 12

What’s infiltration?

Answer 12

It’s when water above ground moves underground

Question 13

What’s runoff?

Answer 13

It’s when water coming from rain that moves on the surface moves downslope

Question 14

What is groundwater (Aquifer)?

Answer 14

It’s water thats stored in pore space of premeable rock & sediment layers

Question 15

What causes saltwater intrusion?

Answer 15

When excessive pumping near the coast lowers the water table pressure, allowing saltwater to seel into ground water.
