Water Cycle

1. What is evaporation?

• It is the process by which water vapor in the air is changed into liquid water.

• It is the process by which liquid water becomes water vapor

How does the process of evaporation happens?

• This process happens when the water is heated, its molecules move faster. The molecules bump into each other and bounce. These molecules escape into the air.

• This process happens when the weather is cold, cold enough to evaporate the particles of water into the air. The molecules gather together to evaporate the water.

What is Condensation ?

• Condensation is the process by which water vapor in the air is changed into liquid water.

• Condensation is the process in which the rain comes down from the clouds.

The process of condensation happens when the air cools, Because cool air cannot hold as much water vapor as warm air can, the water vapor begins to turn back into very tiny droplets of liquid

• True

• False

Condensation is not important for water cycle

• True

• False

What is due point ?

• The temperature at which water get frozen

• The temperature at which water condense

What is precipitation ?

• Precipitation is any form of water which falls from the clouds to the earth.

• Precipitation is when the earths moves so fast and it precipitates

The only way of precipitate is rain

• True

• False

The process of precipitation happens

When the drop of water become too large and heavy to stay in the cloud, they fall to earth as rain or in other forms.

• True

• False

The three stages of water cycle are:

• Evaporation, condensation, precipitation

• Cold, ice and foggy
