1
Q
Name 3 reasons why it’s so cold in Antarctica
A
The albedo effect
Tilt of the earth
Angle of incident
2
Q
Define the albedo effect
A
The albedo effect is when white surfaces such as snow reflect all the sunlight, making it very cold
3
Q
Explain why the angle of incidence will effect the climate
A
The suns rays are spread out over a large surface areas so are less concentrated
