Important Questions Class 7 Science Chapter 7-Weather, Climate and Adaptations of Animals to Climate

Chapter 7 of Science Class 7 is about ‘Weather, Climate and Adaptations of Animals to Climate’. The chapter covers three important topics:

• Weather: It includes parameters such as temperature, humidity, rainfall, wind speed, etc., which are not the same on any given two days and vary over a very short period of time. Hence, it is difficult to predict the weather of a place. All the changes in atmospheric conditions are caused by the sun. A typical daily and weekly weather report shows the maximum temperature, minimum temperature, max humidity, min humidity, and rainfall recorded at a given place.
• Climate: It is the average weather pattern calculated over a long period of time. For example, if we find the temperature of a place is very hot most of the time, then we can say that the climate of that place is hot. The climate is easy to predict.
• Climate and adaptations: This section covers the important aspects of adaptations of animals living in polar regions and tropical rainforests.

(a) Polar regions 

(b) Deserts

(c) Oceans

(d) Tropical rainforests

Answer 9. (d) Tropical rainforests.

Explanation: As mentioned in the question, stripes on the body of a carnivore animal illustrate those of a big cat like a tiger. Tigers are found in abundance in tropical rainforests. Some adaptations of such tropical animals are stripes on their body, living on the trees, development of strong tails, large beaks, bright colours, loud voices, a diet of fruits, sensitive hearing, sharp eyesight, thick skin, and the skin colour helps them to incorporate with the surroundings and camouflage, to protect themselves from predators.

Question 10. Differentiate between:

(a) Weather and climate

(b) Humidity and rainfall

(c) Climates of the tropical rainforest and polar region

(d) Minimum and maximum temperatures of the day

Answer 10. 

(a) Weather and climate:

Weather is the day-to-day atmospheric condition of a given place concerning temperature, humidity, rainfall, wind speed, etc.,

Climate is the average weather pattern recorded over many years. For example, if the temperature at a place is high most of the time, we can say that the climate is hot.

(b) Humidity and rainfall:

Humidity is the measure of moisture or wetness in the air.

Rainfall is the amount of rain (water droplets) that falls at a certain time.

(c) Climates of the tropical rainforest and polar region:

The climatic conditions of the polar regions are extreme. These regions are very cold and covered with snow for most of the year.

Tropical rainforests have a hot and humid climate due to their location around the earth’s equator.

(d) Minimum and maximum temperatures of the day:

The maximum temperature is the highest recorded temperature on a given day. It is likely to occur in the afternoon.

Minimum temperatures are the lowest recorded temperature in a given day. It is likely to occur in the early morning.

Question 11. Which of the following statements is incorrect for penguins?

(a) They huddle together

(b) They cannot swim

(c) They have webbed feet

(d) They have streamlined body

Answer 11. (b) They cannot swim.

Explanation:

(a) They huddle together: Penguins are adapted to living in polar regions with very cold climates. To adapt to such severe conditions and keep themselves warm, penguins have thick skin, a lot of fat, and they huddle together. Hence, option (a) is correct.(b) They cannot swim: Penguins are very good swimmers. Hence, option(b) is incorrect.

(c) They have webbed feet: Penguins have webbed feet that aid in swimming.

(d) They have a streamlined body: It is correct that they have a streamlined body.

Question 12. When are the minimum and maximum temperatures likely to occur during the day?

Answer 12. The maximum and minimum temperatures are recorded daily using a thermometer. The maximum temperature generally occurs in the afternoon, and the minimum temperature occurs in the early morning.

Question 13. Explain which of the two changes frequently, weather or climate?

Answer 13. Weather frequently changes as compared to the climate. Temperature, humidity, rainfall, wind speed, etc., are the parts of the weather that keep changing day after day and week after week, hence they can be referred to as short-term atmospheric conditions.

Climate is the atmospheric changes over longer periods, generally 30 years or more. For example, if the temperature at a place is usually cold, then we say that the climate of that place is cold.

Question 14. How do elephants living in the tropical rainforest adapt?

Answer 14: Tropical rainforests are hot and have abundant rainfall. They are found in Central America, Central Africa, the Western Ghats, Assam in India, and Southeast Asia. Elephants live in tropical rainforests; their adaptations to the climatic conditions are:

1. Elephants use their trunks as a nose to smell and breathe. It also serves purposes like drinking water, bathing, and eating.
2. Along with the 24 molar teeth, elephants have two tusks and long incisor teeth in the front. They help dig, lift objects, gather food, strip bark from trees to eat, and defend it.
3. The elephant’s large ears are very helpful for hearing sounds from long distances and regulating the body temperature in the hot and humid climate of the rainforest.

Question 15. State whether the below statements are True or False. Correct the false statements.

(a) Since very few prey are available, polar bears do not need to have a strong sense of smell.

(b) It is easy to predict weather rather than climate.

(c) Tropical rain forests are cool and humid throughout the year because of heavy rains all the time.

(d) Penguins stick together to fight the cold polar climate.

Answer 15. (a) False; polar bears need a strong sense of smell to detect the prey since very few preys are available.

(b) False: It is easier to predict climate than the weather.

Weather is a complicated process and difficult to predict, as it changes rapidly over a short time.

Climate is the average weather/atmospheric change of a place, taken over a long period. Hence, it is easy to predict the place’s climate based on the recorded average weather( hot, humid, cold, rainy).

(c) False, Tropical rain forests are hot and humid throughout the year because of heavy rains.

(d) True.

Question 16. Name two animals each that live in the Polar region and Tropical rainforests.

Answer 16. Polar region: polar bear, penguin

Tropical rainforest: tiger, elephant

Question 17. Give two examples of animals that can live both in water and on land.

Answer 17. Frogs, Crocodiles
