Weather How It Impacts Our Lives

Question 1

What is the atmosphere

Answer 1

A thin layer of gases that surrounds the earth

Question 2

What is the atmosphere made up of

Answer 2

78 percent nitrogen 21 percent oxygen and 1 percent random gases

Question 3

What does the atmosphere do

Answer 3

It insulates the earth from extreme temperatures

Question 4

How thick is the earth’s atmosphere

Answer 4

480km thick

Question 5

Troposphere

Answer 5

The bottom layer of the atmosphere
Weather and clouds r found
Temp generally decreases as the altitude increases

Question 6

Stratosphere

Answer 6

2nd layer
Extends from 17km to 50km
Ozone layer is located here

Question 7

Solar energy

Answer 7

Energy from the sun
Earth’s main source of heat
Energy that travels form the sun through space is solar radation

Question 8

Latitude

Answer 8

The angular distance north or south of the equater

Question 9

Near the equator (lower latitude)

Answer 9

Sun’s rays heat a small area
Sun’s rays travel through less atmosphere so don’t loose much heat

Question 10

Away from the equator (higher latitude)

Answer 10

Sun’s rays r more spread out
Colder

Question 11

Wind

Answer 11

The movement of air from areas of high pressure to areas of low pressure

Question 12

Trade winds

Answer 12

Air movements towards the equator
Warm, steady breezes that blow almost continuously

Question 13

The doldrum

Answer 13

Areas near the equator where is little to no wind

Question 14

The prevailing westerlies

Answer 14

Prevailing winds form the west to the east in the middle latitudes between 30° and 60°

Question 15

The horse latitudes

Answer 15

Found at 30° North and South of the equator. Weak and encourage clear skies

Question 16

The polar easterlies

Answer 16

Dry, cold prevailing winds that blow from the east.

Question 17

Where are the polar easterlies found

Answer 17

Between 60° and 90° North and South latitude that blow from the poles and are deflected towards the east

Question 18

Warm currents

Answer 18

Currents flowing from the equator
Raise the temp of the water to which they flow
Help to keep harbours in higher latitude free from ice

Question 19

Cold currents

Answer 19

Flow from areas in high latitudes towards the equator
Lower the temp of the water to which they flow. increase the possibility of ice in higher latitude harbours

Question 20

Air masses

Answer 20

Large moving pockets of air that have similar temperature, pressure and moisture throughout

Question 21

Size of air masses

Answer 21

Large, stretching 1,500 km across the landscape

Question 22

Warm air masses

Answer 22

Carry warm moisture or water vapor than cold air masses

Question 23

Polar maritime

Answer 23

Air masses from the north-west Atlantic that bring cold, wet air and showery conditions

Question 24

Arctic

Answer 24

Air masses from the North Pole bring cold weather conditions

Question 25

Polar continental

Answer 25

Air masses from north-east Europe bring dry, cold and frosty nights and heavy snowfall in winter

Question 26

Tropical continental

Answer 26

Air masses from the Sahara bring dry, sunny weather

Question 27

Tropical maritime

Answer 27

Air masses from the south-west bring rain all year round

Question 28

Isobars

Answer 28

Lines drawn on a weather map connecting places of equal atmospheric pressure Closer they are, stronger the wind will be

Question 29

Warm fronts

Answer 29

Occurs when a warm air mass approach a cold air mass. As the warm air rises, it cools and condenses to form dark, rain-bearing clouds

Question 30

Cold fronts

Answer 30

Occurs when a cold air mass pushes in and replaces a warm air mass. Warm air rises, cools and condensation takes place. Heavy rain fall

Question 31

Occluded front

Answer 31

Occur at the point where a _cold front takes over a warm front_ or the other way around. Brings changeable weather
