Q

What a re the reasons for countries closer to the equator being Warner and countries further being cooler?

A

At the poles the atmosphere is thicker and so not as much heat gets through there

At the equator the sun sines directly overhead which means heat is concentrated on a small area and that area will become hot

At tech poles the Suns energy is slanted and has to heat up a larger area so this area does not heat up as much

22
Q

How do cold fronts occurs

A

A cold front occurs when cold air moves towards warm air
The cold air forces the light warm air to rise
As the warm air rises it cools and condensation occurs
Clouds are formed and this leads to heavy rainfall

Q

How are warm fronts formed

A

A warm front develops when warm air moves in toward cold air
The warm light air rises up over the cold air
As it rises it cools and condensation occurs
Clouds are formed and this ,ends to rainfall

Few clouds and a gentle breeze

32
Q

How are clouds made

A

When water vapour condenses into tiny droplets

33
Q

What a re the three type of clouds

Q

What is precipitation

A

Rain

47
Q

What is the Most common type of precipitation

A

Rain

48
Q

How does rain occur

A

When warm air is forced to rise. As it rises it cools. Cold air cannot hold as much water vapour as warm air so condensation occurs. Clouds are formed and rain occurs

49
Q

Why are there 3 different types of rain

A

Because there are 3 different reasons why warm air is forced to rise

50
Q

How many different types of rain is there

A

3
