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.

2) Changes in weather :- 
     The weather is generally not the same on any two days and there is 
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 
table below and observe the changes in temperature, humidity and 
rainfall for a week.

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.
