Weather, Climate and 
Adaptations 
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

1) 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

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 ofthe place is hot and 
wet. Eg :- Kerala
If the temperature at a place is hot for most 
of the daysand if there is less rainfall, then we
