Question 6

What is latitude measures in

Answer 6

Degrees

Question 7

Wind

Answer 7

Wind is moving air

Question 8

Why do some places have high or low pressure?

Answer 8

War, air rises leaving areas of low pressure. Cold air descends creating areas of high pressure

Answer 12

Is a body of air with its own temperature, pressure and level of humidity

Question 13

Name a cold air mass

Answer 13

Polar air mass

Question 14

Name a dry air mass

Answer 14

Continental air mass

Question 15

Name a warm air mass

Answer 15

Tropical air mass

Question 16

Name an air mass that brings rain

Answer 16

Maritime air mass

Question 17

Front

Answer 17

Is a boundary area where 2 different air masses meet

Question 18

Cold front

Answer 18

Occurs when cold air moves in towards warm air

Question 19

Warm front

Answer 19

Develops when warm air moves towards cold air

Question 20

Depressions

Answer 20

Is an area of low atmospheric pressure

Question 21

Anticyclones

Answer 21

Is an area of high pressure

Question 22

Clouds

Answer 22

Made when water vapour condenses into tiny droplets

Question 23

Precipitation means….

Answer 23

Hail, rain, sleet or snow

Question 24

Rain occurs when…

Answer 24

Warm air is forced to rise. As it does so, it cools. Cold air cannot hold as much water vapour as warm air so condensation occurs. Clouds are formed and rain occurs

Question 25

Rainfall relief

Answer 25

Occurs when moist air moves in from the sea

Question 26

Frontal rainfall

Answer 26

Occurs when cold air masses meet at a front

Question 27

Conventional rain

Answer 27

Occurs when the sun shines on the land and heats up the air above

Question 28

Mean temperature

Answer 28

(Do it by average)

Question 29

What is precipitation measured in

Answer 29

A rain gauge

Question 30

Beaufort scale

Answer 30

Describes the effect the wind has on a landscape

Question 31

The greenhouse effect

Answer 31

- When the sun shines it's heats up the earth - some heat gets trapped in gases in the atmosphere -

Question 32

Global warming

Answer 32

Is when the suns heat is being trapped die to the increase of greenhouse gases

Question 33

The atmosphere

Answer 33

Is a blanket of gas surrounding the earth

Question 34

Name the 3 types of rainfall

Answer 34

Rainfall relief Conventional rain Frontal rainfall

Question 35

Name 2 examples of clouds

Answer 35

Currus | Cumulus

Question 36

How does a cold front occur

Answer 36

- When the cold air forces the light warm air to rise - as the warm air rises, it cools and condensation occurs - clouds are formed and this leads to heaven rainfall

Question 37

How are warm fronts formed

Answer 37

- The warm light air rises up over the cold air - as it rises it cools and condensation occurs - clouds are formed and this leads to heavy rainfall
