• relief
• convectional

Question 2

Answer 2

1. areas of warm and cold air are blown towards eachother
2. the lighter, less dense air is forced to rise over the denser cold air
3. frontal rain produces a variety of clouds bringing moderate rain

Answer 3

1. the prevailing wind picks up moisture from the sea
2. the moist, warm air is forced to rise. cool and condense forming clouds
3. the air drops down over the mountain, warming as it does. as it warms, the amount of water It holds increases, meaning little rain occurs

Question 4

how does convectional rain form

Answer 4
