4.4 Clouds and precipitation

When water evaporates, the water vapour is absorbed into the air. So air around you always contains water vapour. 

When the temperature drops, the water condensates. Clouds of water droplets are being formed.

The amount of water in the air is variable.

1. The higher the temperature the more water the air can hold.
2. The higher the temperature the more water vapour the air can hold.
3. The higher the water temperature the more air it can hold.
4. The higher the water temperature the more water the air can hold.

At night when the temperature drops, air can hold less water vapour, water droplets:

1. fall from the sky
2. collide and form always severe hurricanes
3. appear at places where the air comes into contact with a cold surface.
4. evaporate to steam.

Why is a hot-air balloon called an airship?

1. It floats above the dew point
2. It floats better above the ocean and see
3. It floats above the clouds
4. It floats above air of higher density

This insect is

1. Very dead and solidificated by water droplets
2. frozen solid
3. Transpiring a lot because of al his / her high altitude flying
4. caught in morning dew

Winter dew

Summer dew

Fake dew

Dew to drink
