The weather is generally not the same on any two days and week after week.
The maximum temperature of the day occurs generally in the afternoon while the minimum temperature occurs in the early morning.
The times of sunrise and sunset also change during the year.
The tropical and the polar regions are the two regions of the earth, which have severe climatic conditions.
The polar regions are very cold throughout the year. The sun does not set for six months in a year and in the other six months it does not rise.
Animals in the polar region are adapted to the extremely cold climate by having some special characteristics such as white fur, strong sense of smell, a layer of fat under the skin, wide and large paws for swimming and walking, etc.
Migration is another means to escape the harsh, cold conditions.
Animals in the tropical rainforests are adapted such that they eat different kinds of food to overcome the competition for food and shelter.
Weather describes the changes that take place in the atmosphere at a given place and time.
The tilt of the Earth's axis of rotation with respect to the plane of its orbit around the sun causes seasons on the Earth.
The climate is warmer at places closer to the equator than the places closer to the poles.
Adaptations may be a physical adaptation or it may be the way the animal behaves.
Camels have long eyelashes, ear hair, nostrils that they can close, thick eyebrows, wide feet, hump storing fat, thick lips which help in surviving in the desert heat.
It is hot and humid in the tropics and quite warm in the temperate regions.
Some large fish and mammals in cold climates keep their bodies warm by excessive muscular activity and thick, waterproof fur.
Some animals in cold areas enter into state of dormancy during cold winter season.
Evaporation of water from the body leaves a cooling effect. Many animals in hot and humid climates do so by active sweating, panting, and licking.
