Answer 2

2. Cold fronts occur when warm fronts and cold fronts collide, and driven upward.
3. The cold front never rises, but the warm front does.

Cold front.

Question 4

Which comes first?

Answer 4

The warm front.

Question 5

Summarise how weather changes as a depression (warm/cold) front passes.

Answer 5

When it’s a warm front (which always comes first) the warm air moves and rises slowly above cold air, which creates Nimbostratus clouds.
When it’s a cold front (which comes after the warm front) the cold air moves and violently pushes the warm air upwards making Cumulonimbus clouds.
