Drag the words below to the correct boxes. 

Two air masses meet

Water vapour condenses

Air cools down

Air meets a mountain

Air starts rising

The air is very warm

So conclusion: 

- Rain always forms when air rises. Since the air cools down, and water vapour condenses to form clouds and rain.

There are three different reasons why the air rises:

- A mountain (relief rainfall), to colliding air masses (frontal rainfall), heat (convectional rainfall)

Low air pressure

High air pressure

Very cold day in the winter

Air rises

Air moves down

Rainy

Clear skies

Sunny

Strong winds

Warm day in the summer

Not very cold in the winter

It is a warm day in July with clear skies. The wind most likely comes from the ...

1. Northeast
2. Southeast
3. Northwest
4. Southwest

- Why east? 
When the wind comes over land, it is very warm in the summer (and very cold in the winter). The land warms up quickly, and cools down quickly.

- Why south? 
Wind from the south (equator) is warmer than wind from the north (north pole).

It is a rainy day in the winter. The wind most likely comes from the ...

1. West
2. East

- Why west? 
When the wind comes over sea, there is more water vapour in the air than when the wind comes over land. So it rains more.

There are icy cold winds blowing over the Netherlands. The wind comes from the ...

1. Northwest
2. Northeast

- Why east? 
When the wind comes over land, it can be very cold in the winter. The land cools down quickly. If the wind comes over sea, the wind is warmed up by the sea because the sea doesn't cool down quickly.

It is a mild but rainy day in May. The wind comes from the ...

1. Southwest
2. Northeast

- Why west? 
It is rainy and wind over sea brings more water vapour than wind over land. 

- Why south?

If the wind came from the north, it would have been colder (since the wind would have come from the north pole).
