Question 21

how are tempretures diffrent across the earths surface?

Answer 21

the tempretures are diffrent as ir tis hotter near to the equator this is because the lower the latitude the less atmosphere it has to pass through therefore the sun rays are more condense

Question 22

state 2 factors that can effect tempretures ( apart from latitude)

Answer 22

higher land is cooler
cloudy tempreture reduces temp

Question 23

how can the angle of sun rays effect a diffrence in tempreture

Answer 23

the angle of sun rays cause this diffrence in tempreture because if the rays are directly overhead at 90 degrees it will be warmer and if the sun rays are coming in at 45 degrees they have a further distance to travel therefore it is cooler.

In the summer, the sun is directly overhead and its rays hit the earth directly. In the winter months, the sun sits lower on the horizon. This causes the rays to hit the earth at an angle.
