Basic Science Class 6 Bharati Bhawan Solution Chapter 16 : PART A

Question: 1. Which is the most abundant compound on the earth, name three of its main uses.

Answer: 1. Water is the most common compound found on Earth. We use water in three main ways – for household activities, in agriculture, and in industries.

Question: 2. Name one biochemical reaction in which water takes part.

Answer: 2. Photosynthesis is a process where water, carbon dioxide, sunlight, and chlorophyll react together to form glucose.

Question: 3. The water requirement of wheat is 500. What does this mean?

Answer: 3. When we say wheat requires 500 water units, it means we need 500 liters of water to grow 1 kilogram of wheat.

Question: 4. Name any three purposes for which water is used in industry.

Answer: 4. Water is used in industries as a reactant, solvent, and for waste disposal.

Question: 5 HOW is a reservoir of groundwater formed?

Answer: 5. When rainwater goes into the soil, it passes through rocks until it reaches impermeable rocks. Above these rocks, water accumulates and forms groundwater.

Question: 6. What do you mean by precipitation?

Answer: 6. When water from the atmosphere falls to the Earth in any form, like liquid or solid, it’s called precipitation.

Question: 7. What is rainwater harvesting?

Answer: 7. To conserve water, we can practice rainwater harvesting. This means collecting rainwater and using it instead of letting it go to waste.

Question: 1. Explain what you mean by evaporation.

Answer: 1. When a liquid turns into vapor below its boiling point, it’s called evaporation.

Question: 2. You are provided with a glass, a shallow dish and some water. Describe an activity to show how Evaporation depends upon surface area.

Answer: 2. If we take a glass and a shallow dish made of the same material, and pour equal amounts of water in them, the water in the shallow dish will evaporate faster in the sun. More surface area leads to faster evaporation.

Question: 3. In what ways is evaporation affected by heat, humidity, and a draught?

Answer: 3. Evaporation happens faster with high temperature, low humidity, and when there’s a breeze.

Question: 4. What is the difference between fog and clouds?

Answer: 4. In cold weather, water vapor condenses at low heights and forms fog. Higher up in the sky, clouds are formed when water vapor condenses around dust particles.

Question: 5. What happens when there is little or no rainfall?

Answer: 5. When there’s no rain for a year or more, it leads to a drought. This causes problems for farmers as there’s not enough water for their crops, and it also affects drinking water supply.

Basic Science Class 6 Bharati Bhawan Solution Chapter 16 : PART C

Question: 1. Discuss why water is required in agriculture.

Answer: 1. Crops need water for photosynthesis, to absorb minerals from the soil, and for transporting substances within the plant. They lose a lot of water through transpiration, which is more than what they need for other purposes. So, the soil should have enough moisture to support the crops.

Question: 2. How would you prove through an activity that a current of air helps a liquid evaporate? Give an Example from everyday experience to show this.

Answer: 2. If we take two shallow dishes with water and place one under a fan and the other away from the fan, the water under the fan will evaporate faster. The moving air blows away the vapors, allowing fresh vapors to form, which speeds up evaporation. This is why clothes dry faster in the wind.

Question: 3. Explain how snow and hailstones are formed.

Answer: 3. High up in the atmosphere, water freezes into ice crystals due to very cold temperatures. These crystals fall as snowflakes when they become heavy. Sometimes rain freezes into hailstones when passing through a very cold layer of air.

Question: 4. What happens to the rain that falls over land? Describe one way of making use of rainwater.

Answer: 4. Rainwater that falls on the land either flows into the oceans through rivers and streams or seeps through the soil and collects as groundwater. We can dig pits or tanks in low-lying areas to collect rainwater, which can then be filtered and treated for drinking.
