5. Location of Mountain Ranges
The mountain range at a place too influences the climate of a place. Icy winds blow in
central Asia, but the Himalayas do not allow them to cross over to India, so India is not
as cold as Tibet. On the other hand, the Himalayas check the monsoon winds from

going over to central Asia, and this brings rainfall to India.

Climatic Zones

You have read in this book that there are three heat zones in the world. They are also
called the climatic zones, as they determine the climate of the world.

1. Torrid Zone : The very hot zone is called Torrid
Zone. This area receives direct sunlight from the North Pole
90°N
sun, so it remains hot throughout the year. 66½°N Frigid Arctic Circle
Zone
2. Frigid Zone : The very cold zone is called Frigid
Zone. There are two frigid zones, called North 23½°N North Temperate Zone Tropic of
Cancer
Frigid Zone and South Frigid Zone. As sunlight is
very slanting here, this area remains almost frozen 0° Equator

throughout the year.
3. Temperate Zone : The moderate zone is called 23½°S Tropic of

Temperate Zone. There are two temperate zones, South Temperate Zone Capricorn
called North Temperate Zone and South Temperate Frigid
66½°S Zone Antarctic Circle
Zone. This area is neither too hot nor too cold, as
90°S
the sunlight is slightly slanting in this area. South Pole

Weather Forecast
If we know the coming weather, we can get ready for this. For example, if you know
that it will rain today, you can carry a raincoat. Predicting the weather is called

weather forecast. It is carried by almost all newspapers and news channels.

Know It!
v The science of weather forecasting is called meteorology and the people who do this are called
meteorologists . Some people call them ‘weathermen’.

There is a meteorological department in
each district. It forecasts the weather for
the next few days. A weather forecast is
made with the help of satellites. It
includes such information as climate,
temperature, speed of wind, cloudy or
Weather forecast in a newspaper A satellite
sunny, humidity etc.
