(c) 1 and 3
(d) 1, 2 and 3
Answer
Answer: (d)
Explanation:
The fruits of the cotton plant (cotton bolls) are about the size of a lemon. After maturing, the bolls burst open and the seeds covered with cotton fibres can be seen. From these bolls, cotton is usually picked by hand. Fibres are then separated from the seeds by combing. This process is called ginning of cotton. Ginning was traditionally done by hand. The process of making yam from fibres is called spinning. In this process, fibres from a mass of cotton wool are drawn out and twisted. This brings the fibres together to form a yam. The process of arranging two sets of yams together to make a fabric is called weaving.

(a) Only 1
(b) Only 2
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer
Answer: (a)
Explanation:
The place where organisms live is called habitat. Habitat means a dwelling place (a home). The habitat provides food, water, air, shelter and other needs to organisms. Several kinds of plants and animals live in the same habitat. The plants and animals that live on land are said to live in terrestrial habitats. Some examples of terrestrial habitats are forests, grasslands, deserts, coastal and mountain regions. On the other hand, the habitats of plants and animals that live in water are called aquatic habitats. Lakes, rivers and oceans are some examples of aquatic habitats. There are large variations among terrestrial habitats like forests, grasslands, deserts, coastal and mountain regions located in different parts of the world.
3. Which of the following is/are true for adaptation?
1. Adaptation takes place in a short time.
2. Those organisms which cannot adapt to these changes die.
(a) Only 1
(b) Only 2
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer
Answer: (b)
Explanation:
Adaptation does not take place in a short time because the abiotic factors of a region also change very slowly. Those organisms which cannot adapt to these changes die, and only the adapted ones survive. Organisms adapt to different abiotic factors in different ways. This results in a wide variety of organisms in different habitats.
4. Which of the following is/are true for desert plant?
1. Desert plants lose very little water through transpiration
2. The leaves in desert plants are absent.
(a) Only 1
(b) Only 2
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer
Answer: (a)
Explanation:
Desert plants lose very little water through tran-spiration. The leaves in desert plants are either absent, very small, or they are in the form of spines. This helps in reducing loss of water from the leaves through transpiration. The leaf-like structure you see in a cactus is, in fact, its stem. Photosynthesis in these plants is usually carried out by the stems.
5. Which of the following is/are true for mountain plants and animals?
1. Trees are normally circular shaped and have sloping branches.
2. Yaks have long hair to keep them warm.
3. Snow leopard has thick fur on its body
(a) 1 and 2
(b) 2 and 3
(c) 1 and 3
(d) 1, 2 and 3
Answer
Answer: (b)
Explanation:
The trees are normally cone-shaped and have sloping branches. The leaves of some of these trees are needle-like. This helps the rainwater and snow to slide off easily. There could be trees with shapes very different from these that are also present on mountains. They may have different kinds of adaptations to survive on the mountains. Animals living in the mountain regions are also adapted to the conditions there. They have thick skin or fur to protect them from cold. For example, yaks have long hair to keep them warm. The snow leopard has thick fur on its body including feet and toes. This protects its feet from the cold when it walks on the snow. The mountain goat has strong hooves for running up the rocky slopes of the mountains.
6. Which of the following is/are correctly matched?
1. Biotic _______ living components
2. Abiotic _______ non-living components
3. Predators _______ animals to eat
(a) 1 and 2
(b) 2 and 3
(c) 1 and 3
(d) 1, 2 and 3
Answer
Answer: (a)
Explanation:
The organisms, both plants and animals, living in a habitat are its biotic components. The nonliving things such as rocks, soil, air and water in the habitat constitute its abiotic components. A deer is a animal that lives in forests and grasslands. It has strong teeth for chewing hard plant stems of the forest. A deer needs to know about the presence of predators (animals like lion that make it their prey) in order to run away from them and not become their prey. Lions light brown colour helps it to hide in diy grasslands when it hunts for prey (animals to eat).
Water MCQ Questions
1. What is/are true for rainwater harvesting?
1. It is to collect rainwater and store it for later use.
2. There are two techniques for it.
(a) Only 1
(b) Only 2
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer
Answer: (c)
Explanation:
One way of increasing the availability of water is to collect rainwater and store it for later use. Collecting rainwater in this way is called rainwater harvesting. The basic idea behind rainwater harvesting is “Catch water where it falls”. Two techniques of rainwater harvesting are-
1. Rooftop rainwater harvesting: In this system, the rainwater is collected from the rooftop to a storage tank, through pipes. This water may contain soil from the roof and need filtering before it is used. Instead of collecting rainwater in the tank, the pipes can go directly into a pit in the ground. This then seeps into the soil to recharge or refill the groundwater.
2. Another option is to allow water to go into the ground directly from the roadside drains that collect rainwater.
2. Which of the following is/are true for condensation in water cycle?
1. At sufficient heights, the air becomes so cool that the water vapour present in it condenses to form tiny drops of water called droplets
2. It so happens that many droplets of water come together to form larger sized clouds
(a) Only 1
(b) Only 2
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer
Answer: (a)
Explanation:
The process of condensation plays an important role in bringing water back to the surface of earth. As we go higher from the surface of the earth, it gets cooler. When the air moves up, it gets cooler and cooler. At sufficient heights, the air becomes so cool that the water vapour present in it condenses to form tiny drops of water called droplets. It is these tiny droplets that remain floating in air and appear to us as clouds. It so happens that many droplets of water come together to form larger sized drops of water. Some drops of water become so heavy that they begin to fall. These falling water-drops are, what we call rain. In special conditions, it may also fall as hail or snow.
Air Around us MCQ Questions
1. Which of the following is/are correctly matched?
1. Water vapour _______ important for water cycle
2. Nitrogen _______ supports burning
3. Dust _______ combination of gases
(a) 1 and 2
(b) 2 and 3
(c) 1 and 3
(d) 1, 2 and 3
Answer
Answer: (c)
Explanation:
When air comes in contact with a cool surface, it condenses and drops of water appear on the cooled surfaces. The presence of water vapour in air is important for the water cycle in nature. The presence of some components in the air, do not support burning. The major part of air (which does not support burning candle) is nitrogen. The burning of fuel also produces smoke. Smoke contains a few gases and fine dust particles and is often harmful. That is why you see long chimneys in factories.
2. Which of the following is correct order with respect to amount present in air?
(a) Nitrogen > carbon dioxide > oxygen
(b) Nitrogen > oxygen > carbon dioxide
(c) Oxygen >nitogen > carbon dioxide
(d) Carbon dioxide > nitrogen > oxygen
Answer
Answer: (b)
Explanation:
By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% Argon, 0.04% carbon di-oxide and small amount of other gases. Air also contains variable amount of water vapour, on av-erage around 1% at sealevel and 0.4% over the entire atmosphere.
3. Which of the following is/are true for wind mill?
1. The windmill is used to draw water from tubewells and to run flour mills.
2. Windmills are also used to generate electricity-
(a) Only 1
(b) Only 2
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer
Answer: (c)
Explanation:
The wind makes the windmill rotate. The windmill is used to draw water from tubewells and to run flour mills. Windmills are also used to generate electricity. Air helps in the movement of sailing yachts, gliders, parachutes and aeroplanes. Birds, bats and insects can fly due to the presence of air. Air also helps in the dispersal of seeds and pollen of flowers of several plants. Air plays an important role in water cycle.
