Weather, Climate and Adaptations of
Animals to Climate
1) Weather :-
The day to day condition of the atmosphere at a place
with respect to temperature, humidity, rainfall, wind speed
etc. is called the weather at that place.
The temperature, humidity, rainfall, wind speed etc. are
called the elements of the weather.
The weather at a place changes every day. Sometimes it
is more warm, more humid, more cloudy or more windy.
Sometimes it is less warm, less humid, less cloudy or less
windy.

a lot of changes in the weather over weeks and months.
All the changes in the weather is caused by the sun.
From the weather report of news paper, record the information in the

3) Climate :-
The average weather pattern taken over a long period of
time ( about 25 years ) is called the climate of the place.
If the temperature of a place is hot for most of the days
and if there is more rainfall, then we say that the climate of
the place is hot and wet. Eg :- Kerala
If the temperature at a place is hot for most of the days
and if there is less rainfall, then we say that the climate of
the place is hot and dry. Eg :- Rajasthan

4) Climate and adaptations of animals :-
Animals living in very cold climate and very hot climate
should have special features to protect them from heat
and cold.
a) The polar regions :-
The polar regions are very cold for most parts of the
year and the temperatures are as low as – 37
o
C. For six
months the sun does not rise and for six months the sun
does not set. Some of the animals found in the polar
regions are polar bear, penguins, musk oxen, reindeers,
foxes, seals, whales, Siberian crane etc.
