Question 21.
Why do rainforests support a wide variety of plants and animals? Discuss some of the adaptations of animals to the climate of these regions.
Answer:
The tropical rainforests support a wide variety of plants and animals due to continuous warmth and rain. Since the numbers are large, there is intense competition for food and shelter.
This made animals to develop new features which would allow them to survive in such an environment.
For example :

Many animals are adapted to living on the trees. Red-eye frog has developed sticky pads and monkeys have long tails.
As there is competition for food, some animals are adapted to get food not easily reachable, e.g., the bird Toucan possesses a long, large beak to reach distant fruits on fragile branches.
Many tropical animals have sensitive hearing sharp eyesight, thick skin and a skin colour which helps them to camouflage by blending with the surroundings. This is to protect them from predators.

Question 22.
Explain, with examples why we find animals of certain kind living In particular climatic conditions.
Answer:
The organisms interact with the environment to survive. So. it is necessary for the organisms to have characteristics that suits the environment. Let us take the example of polar bear. Polar bears have white fur so that they are not easily visible in the snowy white background. It protects them from their predators. It also helps them in catching their prey.

To protect them from extreme cold, they have two thick layers of fur. They also have a layer of fat under their skin. Physical activities on warm days necessitate cooling. So, the polar bear goes for swimming. It is a good swimmer. Its paws are wide and large, which help it not only to swim well but also walk with ease in the snow. While swimming underwater, it can close its nostrils and can remain underwater for long durations. It has a strong sense of smell so that it can catch its prey for food.

समवायो हि दुर्जयः पाठ का परिचय

प्रस्तुत पाठ में एक चिड़िया की रोचक कथा है। इस कथा में वर्णित है कि कैसे समूह में रहकर और एकता से कार्य करके छोटे-छोटे प्राणी भी विशालकाय हाथी को परास्त कर देते हैं। बहुत से निर्बल प्राणियों का समूह कठिनाई को जीतने योग्य बन जाता है। अत: इस कथा से हमें शिक्षा मिलती है कि सामूहिक एकता में शक्ति होती है।

समवायो हि दुर्जयः Summary

एक वृक्ष पर एक चिड़िया रहती थी। एक बार कोई मस्त हाथी आया और वृक्ष की शाखा को तोड़कर फेंक दिया। इससे चिड़िया के बच्चे पृथ्वी पर गिर कर मर गए। सन्ततिनाश से दुःखित उस चिड़िया को काष्ठकूट पक्षी वीणारवा मक्खी के पास ले गया। उसकी बात सुनकर वह मक्खी उसे मेंढक के पास ले गई।

समवायो हि दुर्जयः Summary Notes Class 7 Sanskrit Chapter 11

उन सभी ने मिलकर एक योजना बनाई। योजना के अनुसार मक्खी ने हाथी के कान में मीठा-मीठा गुनगुनाना प्रारम्भ किया। मस्ती की दशा में वह आँखें बन्द किए पड़ा रहा। इसी समय काष्ठकूट ने उसकी आँखें चोंच से फोड़ डालीं। प्यास से व्याकुल वह हाथी यत्र-तत्र घूमने लगा।

तब एक गड्ढे के पास मेंढक टर्र-टर्र की आवाज निकालने लगा। उसे तालाब समझ कर वह हाथी उस गड्ढे में गिर गया और मर गया। अत: कहा गया है कि मेल (या एकता) दुर्जय होता है।

Clouds bring rain which is vital for survival of living beings. Farmers in our country depend mainly on rain for irrigation.

Wind Storms And Cyclones Class 7 Questions And Answers Question 12.
How does the eye of a cyclone harm us?
Answer:
The low pressure in the eye lifts water surface in the centre. The rising water may be as high as 3-12 metres. It appears like a water-wall moving towards the shore. As a result, the seawater enters the low-lying coastal areas, causing severe loss of life and property. It also reduces the fertility of the soil.

Extra Questions For Class 7 Science Chapter 8 Question 14.
Explain the structure of a tornado?
Answer:
A tornado is a dark funnel-shaped cloud that reaches ground from the sky. The diameter of a tornado can be as small as a meter and as large as a kilometre, or even wider. The funnel of a tornado sucks dust, debris and everything near it at the base (due to low pressure) and throws them out near the top.

Wind Storms And Cyclones Class 7 Extra Questions Question 15.
Suggest three effective safety measures for cyclone.
Answer:

A cyclone forecast and warning service.
Rapid communication of warnings to the Government agencies, the ports, fishermen, ships and to the general public.
Construction of cyclone shelters in the cyclone-prone areas, and administrative arrangements for moving people fast to safer places.

Question 16.
Suggest some precautions in a cyclone hit area.
Answer:

Do not drink water that could be contaminated. Always store drinking water for emergencies.
Do not touch wet switches and fallen power lines.
Do not go out just for the sake of fun.
Do not pressurise the rescue force by making undue demands.
Cooperate and help your neighbours and friends.

Question 17.
Describe the structure of a cyclone.
Answer:
The centre of a cyclone is a calm area. It is called the eye of the storm. A large cyclone is a violently rotating mass of air in the atmosphere, 10 to 15 km high. The diameter of the eye varies from 10 to 30 km. It is a region free of clouds and has light winds. Around this calm and clear eye, there is a cloud region of about 150 km in size. In this region, there are high-speed winds (150-250 km/h) and thick clouds with heavy rain. Away from this region the wind speed gradually decreases.

Question 18.
How does a thunderstorm become a cyclone?
Answer:
Before cloud formation, water takes up heat from the atmosphere to change into vapour. When water vapour changes back to liquid form as raindrops, this heat is released to the atmosphere. The heat released to the atmosphere warms the air around. The air tends to rise and causes a drop in pressure. More air rushes to the centre of the storm. This cycle is repeated. The chain of events ends with the formation of a very low-pressure system with very high-speed winds revolving around it. It is this weather condition that we call a cyclone.

Question 19.
Suggest precautions if storm is accompanied by lightning.
Answer:
If a storm is accompanied by lightning, we must take the following precautions :

We should not take shelter under an isolated tree. If in a forest, take shelter under a small tree.
We must not take shelter under an umbrella with a metallic end.
We should not sit near a window. Open garages, storage sheds, metal sheds are not safe places to take shelter.
A car or a bus with closed windows is a safe place to take shelter.
If in water, we should get out and go inside a building.
We should not lie on the ground.

Question 20.
