Which of the following is the process of changing water vapour into water?

  1. Transpiration

  2. Perspiration

  3. Evaporation

  4. Precipitation

  5. Circulation

Show answer
Correct Option: D
Explanation:

All the droplets collected by evaporation form bigger drops of water. Some of them may become too heavy to remain in the sky and fall down as rain. Thereby, changing from water vapour into water. This process is known as precipitation.

Water vapour gets added to air by _________________ and ______________.

  1. condensation, precipitation

  2. evaporation, condensation

  3. evaporation , transpiration

  4. transpiration, precipitation

  5. transpiration, condensation

Show answer
Correct Option: C
Explanation:

It is correct. Water vapour gets added to air by evaporation and transpiration.

The water that is evaporated from the oceans or seas again ____________ to form water and fills up the rivers and seas.

  1. condenses

  2. transpires

  3. evaporates

  4. precipitates

  5. photosynthesises

Show answer
Correct Option: A
Explanation:

Correct. The process through which evaporated water is converted back to water is called condensation. The water vapor present starts to condense to form tiny water droplets, these droplets float in the air and form cloud and fog and rain . The whole process is called water cycle.

Which of the following are due to evaporation:

(a) Water drops appear on the outer surface of a packet of orange bar ice cream once it is taken out of the freezer. (b) Fog on a cold winter morning. (c) Steam rising from a hot pressure cooker when we are cooking.

  1. Only a

  2. Only b

  3. Only c

  4. Both a and c

  5. Both b and c

Show answer
Correct Option: C
Explanation:

Correct. The steam rising from the pressure cooker is evaporation.

Which of the following is the correct term for the process where rain water is collected from the rooftop to a storage tank, through pipes?

  1. Water Cycle

  2. Conservation

  3. Harvesting

  4. Precipitation

  5. Drought

Show answer
Correct Option: C
Explanation:

Correct. It is roof top rain water harvesting.

Which of the following statements is incorrect?

(a) The process of water changing into its vapour, is called evaporation. (b) Transpiration takes place only during monsoon. (c) Rainwater harvesting is a method of collecting and storing rain water.

  1. Only a

  2. Only b

  3. Only c

  4. Both a and b

  5. Both b and c

Show answer
Correct Option: B
Explanation:

Statement b is incorrect. Hence, this option is right.

Due to lack of rains the wells, lakes, ponds get dried up and thereby creating water scarcity and as result droughts are possible.

What happens to the soil in such near drought conditions?

  1. The soil becomes more dry and patchy.

  2. The soil evaporates.

  3. The soil develops great cracks.

  4. The soil gets eroded with wind.

  5. The soil remains unaffected.

Show answer
Correct Option: A
Explanation:

Correct. If there are no rains, then the soil becomes more dry and patchy.

Many industries use ____________ water to produce everything from paints and fabric to leather and chemicals.

  1. sea

  2. rain

  3. fresh

  4. ground

  5. hard

Show answer
Correct Option: D
Explanation:

It is correct. Many industries use ground water to produce everything from paints and fabric to leather and chemicals.

___________________ happens after the levels in water bodies increase dangerously after excessive rainfall.

  1. Water cycle

  2. Drought

  3. Flood

  4. Precipitation

  5. Harvesting

Show answer
Correct Option: C
Explanation:

Correct. Due to heavy rainfall the water levels in ponds, lakes rises to a greater extent and the rise in the water level of these water bodies causes the excess water to spread across, causing floods.

Which of the following statements is correct?

  1. The life cycle of aquatic organisms is called the water cycle.

  2. Our Earth is covered by three-fourths of water.

  3. A variety of salts, like magnesium and potassium, are present in saline water.

  4. Rain harvesting causes the problem of depleting the ground water.

  5. Ocean and sea water contains many dissolved salts and is beneficial for drinking, agriculture and domestic purposes.

Show answer
Correct Option: C
Explanation:

Correct. A variety of salts, like sodium chloride, calcium, magnesium, and potassium are present in saline water.

Aneesh noticed dew on the leaves of grass and on the iron grills and gates on winter mornings. He asked his mother about it. What did his mother tell him about it?

  1. It was evaporation

  2. It was transpiration

  3. It was condensation

  4. It was precipitation

  5. It was water vapour

Show answer
Correct Option: C
Explanation:

Yes. The air is cool in winters, so that the water vapor present in it condenses to form tiny drops of water called droplets. It was this water after condensation that Aneesh saw on the leaves of grass and on the iron grilles of the gate.

Choose the option that has correctly matched Column A with Column B:

 
Column A Column B
1. Evaporation a. Clouds
2. Transpiration b. Water bodies
3. Condensation c. Plants

  1. 1 - a, 2 - b, 3 - c

  2. 1 - a, 2 - c, 3 - b

  3. 1 - c, 2 - a, 3 - b

  4. 1 - b, 2 - c, 3 - a

  5. 1 - b, 2 - a, 3 - c

Show answer
Correct Option: D
Explanation:

Water in the water bodies evaporates due to heat. Plants undergo transpiration and water vapor in the air condenses to form tiny droplets of water or clouds.

Match the above columns correctly:

 
a. Plants 1. Condensation
b. Oceans 2. Transpiration
c. Clouds 3. Evaporation

  1. a - 1, b - 2, c - 3

  2. a - 1, b - 3, c - 2

  3. a - 2, b - 3, c - 1

  4. a - 3, b - 1, c - 2

  5. a - 2, b - 1, c - 3

Show answer
Correct Option: C
Explanation:

Correct. Plants undergo transpiration while photosynthesis. Water from oceans evaporates to form water vapor. Clouds are  formed upon condensation.

Which of the following takes place during transpiration?

  1. The process by which water is converted from its liquid form to its vapour form.

  2. The absorption of water from air in plants.

  3. The process of water movement through a plant and its evaporation from aerial parts.

  4. The process of preparation of food by plants through absorption of water from soil.

  5. The process in which evaporated water converts back into droplets.

Show answer
Correct Option: C
Explanation:

Correct. The process of water movement through a plant and its evaporation from aerial parts is transpiration.  It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis.

Directions: Answer the question that follows after considering the statement given below:

Our Earth is covered by two-thirds of water but most of the water is not potable.

Why is there scarcity of potable water?

  1. Most of the water is in the oceans.

  2. Most of the water contains aquatic life.

  3. Most of the water contains salt.

  4. Most of the water is frozen in glaciers.

  5. Most of the water is polluted.

Show answer
Correct Option: C
Explanation:

The high salt content in water makes it unusable and unfit for human consumption.
