Factors That Cause Variation In Weather

Question 1

What are the 4 air masses?

Answer 1

Tropical Continental
Tropical Maritime
Polar Continental
Polar Maritime

Question 2

Explain temperature in Altitude

Answer 2

Every 100m we lose 1 degrees. This is known as Lapse Rate.

Air becomes less dense and is less able to hold heat

Question 3

Explain Precipitation in Altitude

Answer 3

Air arriving from Atlantic Ocean is forced to rise over high land in Wales
This creates relief rainfall as it cools and condenses

Question 4

Explain the four air masses?

Answer 4

North East - cold air travelling over cold land. Weather is dry
South East - brings warmer temp as it arrived from warm land
South West - arrives from warm tropical area over the sea brings high temp
North West - arrives from cold polar regions with wet cold weather

Question 5

Explain continentality - Summer

Answer 5

The sea takes longer to warm up and it keeps coastal areas cool

Question 6

Explain continentality- Winter

Answer 6

Sea insulates area near the coast. Because absorbs heat slowly but retains it so costal areas are milder in winter

Question 7

Give five things that affect the weather?

Answer 7

Altitude 
Air masses 
Continentality 
Aspect 
Latitude

Question 8

Explain continentality - Precipitation

Answer 8

As moist air arrives it begins to rise, cool and condenses over the land.

Question 9

Explain Aspect

Answer 9

South Facing receive direct sunlight.

North Facing remain shaded as the sun moves throughout the day

Question 10

Explain Latitude

Answer 10

Equator - The sun is over head and its rays are concentrated over a smaller surface area.
Further North or South the sun rays are spread over greater area so less concentrated
