Question 1

What are air masses?

Answer 1

Air masses are large bodies of air, sharing similar temperature moisture and atmospheric pressure.

Question 2

Where do fronts occur?

Answer 2

Where two different air masses meet.

Question 3

What is a weather map?

Answer 3

Internationally agreed standards and symbols.

Question 4

What is a synoptic chart?

Answer 4

Summarises atmospheric condition such as temperature , perception and wind speed.

Question 5

What is a occluded front?

Answer 5

The point where a cold front overtakes a war front or vice versa. Occluded fronts being changeable weather.

Question 6

What is a depression?

Answer 6

Areas of low atmospheric pressure. Which produce colours , rainy and windy weather.

Question 7

What is a warm front?

Answer 7

Where warm air rises over a mass of cold air. The warm air cools and expands and clouds form.

Question 8

What is an isobar?

Lines on a weather map that join up places of equal atmospheric pressure. The closer together isobars are the windier it is.

Question 9

What is a cold front?

Answer 9

Transition zone where a cold air mass replaces a warm one. The cold gradually moves beneath the warm air. It will rain heavily as the warm air is pushed upwards.

Question 10

What is an anticyclone?

Answer 10

The opposite of depression, they are areas of high atmospheric pressure where the air is sinking.

Question 11

What is a weather front?

Answer 11

The area where two air masses with different temperatures and densities collide, but do not mix.

Question 17

Question 18

What kind of wind do close together isobars bring?

Answer 18

Strong winds

Question 19

What kind of rain do warm fronts bring?

Answer 19

Question 20

What kind of rain do cold fronts bring?

Answer 20

Heavy rain as the warm air is forced up rapidly at the cold front.

Question 21

Is an anti-cyclone a low or high pressure system?

Answer 21

High pressure system

Question 22

are the isobars close or far apart with anti-cyclones?

Answer 22

Far apart.

Question 23
