State whether the following statements are True or False. Correct the false statements. (a) It is easy to predict the weather rather than climate. (b) Since very few preys are available, the polar bear does not need to have a strong sense of smell. (c) Penguins stick together to fight the cold polar climate. (d) Tropical rainforests are cool and humid throughout the year because of heavy rains all the time.
Soln: a) False- It is easy to predict the climate rather than the weather. b) False- polar bear needs to have a strong sense of smell. c) True d) False- Tropical rainforests are hot and humid throughout the year because they are located near the equator.

The coldest region on earth is the – (a) polar region (b) tropical region (c) temperate region (d) coastal region
Soln: The answer is (a) polar region Explanation: Polar regions are covered with snow, and it is very cold for most part of the year. For six months, the sun does not set at the poles, while for the other six months the sun does not rise. In winter, the temperature can be as low as –37°C.

Read the following environmental conditions of tropical rainforests. (i) A hot and humid climate (ii) Unequal lengths of day and night (iii) Abundant rainfall (iv) Abundant light and moisture Identify the conditions from the above list that are responsible for the presence of large number of plants and animals in tropical rainforests. (a) (i) and (ii) (b) (i) and (iii) (c) (i), (iii) and (iv) (d) (ii) and (iv)
Soln: Answer is (c) (i), (iii) and (iv) Explanation: The tropical region has generally a hot climate because of its location around the equator. Even in the coldest month, the temperature is generally higher than about 15°C. During hot summers, the temperature may cross 40°C. Days and nights are almost equal in length throughout the year. These regions get plenty of rainfall. Because of these reasons, tropical rain forests supp
