WEATHER CLIMATE AND ADAPTATIONS OF ANIMALS TO CLIMATE MCQs
:
C
Weather is defined as the atmospheric conditions of a specific place over a short interval of time. Whereas, climate is a long term pattern of weather changes in an area.
:
C
In the afternoon, the Sun is overhead and the rays reach us directly. Hence, for most days, the temperature is maximum around this time. However, it may be noted that this is not a compulsory rule. There may be days when the afternoon is colder due to events like rainfall, snowfall, etc.

Penguins live in the polar regions. These regions are covered with snow throughout the year so the organisms living in these areas have features that support their survival.
:
A
The climate in tropical region is generally hot. The tropics are regions of the Earth which are near the equator and between the Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the southern hemisphere. These regions receive direct sunlight throughout the year and hence the temperature in these regions is high.
:
B
The amount of moisture present in the air is termed humidity. Humidity indicates the likelihood of precipitation, dew or fog. Drought is the long term shortage of water which makes life difficult.
:
A
The region which receives very little rainfall is called a desert. The lack of precipitation makes the region quite hostile for normal plant and animal life. Tropical rain forests get the maximum rainfall.
:
C
Birds need warm weather for survival. When the climate turns cold, birds fly away in groups to places with warmer climates which is suitable for their survival. This phenomenon is called migration. The birds return to their homes when the climate becomes favourable for them.

∙ Rain gauge is an instrument that is used for collecting and measuring rainfall.
∙ Thermometre is an instrument that is used to measure temperature.
∙ Barometre is an instrument which is used to measure the air pressure.
∙ Anemometre is an instrument that is used for measuring wind speed.
