1

what is climate?

atmospheric conditions over a long period of time

2

what is weather?

daily atmospheric conditions

3

if a place is closer to the equator, it is ______

warmer

4

similar latitudes = similar _______

climates

5

how does latitude affect climate?

it affects a place's amount of sunlight

6

what are ocean currents?

steady flows of water in a prevailing direction

7

how does ocean current affect climate?

they affect the air's temperature

8

when is fog created?

when two ocean currents collide

9

how is air's weight measured?

air pressure

10

what does air absorb?

the climate of the air below it

11

when warm air rises, what is the pressure?

low

12

when cool air falls, what is the pressure?

high

13

when is wind created?

when air moves from high to low pressure areas

14

what are westerlies?

prevailing wind in Canada moving west to east

15

when air rises, it _____ and ________

expands / cools

16

what is elevation?

measure of how high you are from sea level

17

when air cools, what does it become?

water vapour => clouds => precipitation

18

what is relief?

the differences in elevation

19

what do mountain ranges do?

block the movement of air, making it cooler and causing air to condense => creates relief precipitation

20

what happens when air masses go over the mountain?

precipitation stops and creates rain shadows

21

what is a rain shadow?

dry areas on the back of the mountain

22

why does being near water affect a place's climate?

as wind blows over water in the summer, it cools the land and in winter the water retains heat, makes the winters mild

23

why do areas near water have more precipitation?

they are closer to a source of moisture

24

what is continental temperature and precipitation like?

-more than 25 temperature range
-less than 1000mm of precipitation

25

what is maritime temperature and precipitation like?

-less than 25 temperature range
-more than 1000mm of precipitation
