Important points to remember from this chapter:

⇒ Everyday condition of the atmosphere at a place concerning the humidity, temperature, rainfall, wind-speed, etc., is known as the weather at that place.

⇒ The weather is usually not the same on any two days & week after week.

⇒The maximum temperature of a day happens usually in the afternoon while the minimum temperature is usually recorded in the early morning.

⇒The times of sunrise & sunset also change during the year.

⇒All the variations in the weather are driven by the sun.

⇒ The average weather pattern taken over a very long period, say 25 years, is called the climate of the place.

⇒ The tropical & polar regions are the two regions of the earth, which have severe climatic conditions.

⇒ Animals are adapted to the conditions in which they live.

⇒ 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 special features such as white fur, a strong sense of smell, a layer of fat under the skin, wide & large paws for swimming and walking, etc.

⇒ Migration is extra means to escape the harsh, cold conditions.

⇒ As the hospitable climatic conditions, huge populations of plants & animals are found in the tropical rainforests.

⇒ Animals in the tropical rainforests are adapted so that they eat different kinds of food to overcome the competition for food and shelter.

⇒ Some adaptations of animals living in the tropical rainforests include living on the trees, long & large beaks, development of strong tails, bright colors, sharp patterns, loud voice, sensitive hearing, the diet of fruits, sharp eyesight, thick skin, ability to camouflage to protect themselves from predators, etc.
