Chapter Review:
-
The moving air is called the wind.
-
Air expands on heating and contracts on cooling.
-
Winds carrying water vapour bring rain.
-
High-speed winds and air pressure difference can cause cyclones.
-
The centre of a cyclone is a calm area. It is called the eye of the storm.
-
The instrument that measures the wind speed is called an anemometer.
-
As warm air rises, air pressure at that place is reduced and the cooler
air moves to that place.
