from sun. These divisions are known as heat zones.
1 Torrid Zone: The climate here is extremely hot. It is the hottest zone on
the Earth.
2 Temperate Zone: The climate here is moderate i.e. neither too hot nor
too cold.
3 Frigid Zone: The climate here is extremely cold. It is the coldest zone
on the Earth.

Q2 Distinguish between weather and climate.

WEATHER
1.Weather is the condition of
atmosphere at a given time and
place.
2. It keeps changing suddenly or

to the higher latitudes towards the poles, the sunrays become
slanting and the areas are cooler.
Q 4 What effect do winds have on the climate of an
area?

from hot areas increase the temperature and the winds blowing
from cold areas decrease the temperature.
Q5 What is global warming? What are its causes?

atmosphere. These gases trap the heat of the sun and increase the
temperature. The average increase in the temperature is known as
global warming.
