1

The proportion of light that is reflected by ice or snow

Albedo

2

What is Climate change?

A large-scale, long-term shift in Earth’s weather patterns or
average temperatures. Encompasses global warming.

3

Biome found at 30 degrees latitude

Hot desert

4

Biome found at 0 degrees latitude

Tropical rainforest

5

Biome found at 60 degrees latitude

Temperate forest

6

Biome found at 90 degrees latitude

Tundra (cold, dry)

7

Natural Climate Change (3 types)

-Cosmic changes (Milankovitch cycles)
-Solar/Sun spot activities
-Volcanic activity

8

Name a cause of anthropogenic (man-made) climate change

Burning of fossil fuels for industry, transport, domestic use.
-This releases gases such as CO2, SO2 and NO2

9

Umbrella term for gases that trap solar radiation in the atmosphere

Greenhouse Gases

10

The type of air cell that moves between 0 and 30 degrees latitude?

Hadley Cells

11

Describe the temperature and movement of air in a Hadley Cell?

-Hot air rises at 0 degrees - causes low pressure

-Cool air sinks at 30 degrees - causes high pressure

12

The type of air cell that moves between 30 and 60 degrees latitude?

Ferrel Cells

13

Describe the temperature and movement of air in a Ferrel Cell?

-Cool air sinks at 30 degrees - causes high pressure

-Hot air rises at 60 degrees - causes low pressure

14

At high pressure is there low or high rainfall?

Low precipitation (remember high and dry)

15

At low pressure is there low or high rainfall

High precipitation

16

The type of air cell that moves between 60 to 90 degrees latitude?

Polar Cells

17

Describe the temperature and movement of air in a Polar Cell?

Hot air rises at 60 degrees - low pressure

Cold air falls at 90 degrees - high pressure

18

Biome associated with 90 degrees?

Cold desert / Tundra

19

Biome associated with 60 degrees?

Temperate forest

20

Biome associated with 30 degrees?

Hot desert

21

Biome associated with 0 degrees?

Tropical rainforest
