Weather

Question 1

Oblique Ray’s

Answer 1

The sun is at a low angle and the Rays must cover a larger area of land due to the earths curve so it takes longer to heat up

Question 2

Vertical Ray’s

Answer 2

Close to the equator. That have less ground to cover so it heats up rapidly and causes it to get very hot

Question 3

Low atmospheric pressure

Answer 3

When air is heated it expands and becomes lighter. It rises and creates low atmospheric Pressure

Question 4

High atmospheric pressure

Answer 4

When air is cooled it becomes heavier and it presses down on the earths surface and creates high atmospheric pressure

Question 5

Wind facts

Answer 5

Winds are named from the direction in which they blow.

Winds most common in an area are the prevailing winds

Question 6

Coriolis effect

Answer 6

As the earth spins on its axis the wind direction changes. Winds are directed to the right of their direction in the northern hemisphere. And to the left of their direction in the Southern Hemisphere

Question 7

Doldrums

Answer 7

Areas close to the equator where winds speeds have slowed down or died down entirely

Question 8

Movement of ocean currents

Answer 8

Unequal heating of the currents.

The prevailing winds
The rotation of the earth

Question 9

North Atlantic drift

Answer 9

Flows north easterly from the Gulf of Mexico

Brings mild winters and rainfall

Question 10

Canaries currents

Answer 10

Flows southerly direction off west Africa

Winds loose moisture and cause little rainfall

Question 11

Labrador current

Answer 11

Flows south from the Arctic Ocean.
Mingles with gulf steam and produces fog
Lowers temperature of ocean

Question 12

Air mass

Answer 12

Large bodies of air that have similar temperature, moisture and pressure

Question 13

Maritime air mass

Answer 13

Bring rain

Question 14

Continental air mass

Answer 14

Dry

Question 15

Polar

Answer 15

Cold

Question 16

Tropical

Answer 16

Warm

Question 17

Cold front

Answer 17

Pushes in and replaces warm air.

Warm air is forced to rise it cools and condenses and causes heavy rain

Question 18

Warm front

Answer 18

Warm air approaches cold air. The cold air is to heavy to rise so the warm air rises on top of the cold air

Cold condenses=dark clouds and heavy rain

Question 19

Occluded front

Answer 19

Cold front overtakes a warm front cause all the warm air to rise leaving no warm air at ground level

Question 20

Isobar

Answer 20

Areas on a map of equal pressure

Question 21

Isotherms

Answer 21

Areas on a map of equal temperature

Question 22

Isohels

Answer 22

Areas on a map of equal sunshine

Question 23

Isohyets

Answer 23

Areas on a map of equal rainfall

Question 24

Depression

Answer 24

Windy and unsettled weather cloudy conditions periods of rain and in winter snow

Question 25

Anticyclone

Answer 25

Cloudless skies and days cold and nights even colder in the winter and in the summer it is warm and dry and light winds

Question 26

Cirrus

Answer 26

Wispy, occur at high altitude and fare weather

Question 27

Cumulus

Answer 27

Fluffy and woolly, occur at medium altitude. bring rain if dark

Question 28

Stratus

Answer 28

Occur at low altitude, bring drizzle light rain and come in thin layers

Question 29

Relief rainfall

Answer 29

Worm moist air blows in from over sea. It meets a coastal mountain range and is forced to rise Air cools and condenses and clouds form and rain falls on the windward side of the mountain On the leeward side a rain shadow is created because of very little moisture

Question 30

Cyclonic rainfall

Answer 30

Cold polar air and moist tropical air masses meet at a front The warm air mass rises over the cold Thai causes warm air to cool and condensation occurs Clouds form and rain falls Rain becomes heavier

Question 31

Conventional rainfall

Answer 31

Earths surface is heated by solar energy The land warms the air and moisture is evaporated The warm moist air rises and cools and condenses and clouds form Heavy showers occur

Question 32

Weather

Answer 32

Word used to describe the state of the atmosphere at any particular time and place. Weather can change everyday

Question 33

Meteorologists

Answer 33

Study, analyse and record the weather and then present it on the weather forecast

Question 34

Measuring temperature

Answer 34

Thermometer Degrees Celsius Isotherms

Question 35

Mean temperature range

Answer 35

Sum of monthly temperature divided by 2

Question 36

Temperature range

Answer 36

Max temperature - min temperature

Question 37

Atmospheric pressure

Answer 37

Barometer Isobars Measured in milibars and hectopascals

Question 38

Humidity

Answer 38

Wet and dry bulb thermometers Percentage Amount of moisture in the air

Question 39

Wind speed and direction

Answer 39

Anemometer - wind speed Weather vane- direction Beaufort scale- wind strength

Question 40

Precipitation

Answer 40

Rain gauge | Multimeter

Question 41
