17
Q

Over the oceans, evaporation exceeds precipitation, what does this result in

A

movement of water vapor over the land.

18
Q

evaporation equations

A

liquid + gas

19
Q

condensation equation

A

gas + liquid

20
Q

precipitation

A

occurs when so much water as condensed, the air can no longer hold it.

21
Q

what is infiltration dependent on

A

the soil and rocktypes

22

A

its when the water is soaked in by the layer of rock, sand or gravel

23
Q

what is igneous rock

A

when hot, molten rock crystallizes and solidifies

24
Q

what are sedimentary rocks formed from

A

deposits of smaller rock particles eroded by water or wind

25
Q

where re metamorphic rocks formed

A

deep underground where there is high heat and pressure

26
Q

what does constant compression of soil result in

A

plants will not survive mainly because there will be less air and water pockets

27
Q

what does albedo effect refer to?

A

the fraction of solar energy reflected from earth back to space

28
Q

if there a black car in a carpark, and it was absorbing the sun would it be low or high albedo?

A

low albedo

29
Q

why does the ocean have low albedo

A

the ocean has low albedo because there are mostly dark colours in the ocean, meaning it absorbs the light instead of reflects

30
