Match List I with List II and select the correct answer using the code given below: List I | List II A. Evaporation | 1. Conversion of water to vapour B. Condensation | 2. Loss of water by plants C. Transpiration | 3. Seepage of water into the ground D. Infiltration | 4. Conversion of vapour to liquid droplets

Correct Option The correct option is A-1, B-4, C-2, D-3 . Explanation The fundamental processes within the hydrological cycle (water cycle). These processes facilitate the continuous movement and phase changes of water across the atmosphere, lithosphere, and biosphere. Detailed Matching - A. Evaporation (Matches 1): This is the physical process by which water changes from a liquid state to a gaseous state (water vapour). It occurs when heat energy breaks the bonds holding water molecules together, primarily from the surfaces of oceans, lakes, and soil. - B. Condensation (Matches 4): This is the process where water vapour in the air cools and changes back into liquid water droplets. It is responsible for the formation of clouds, fog, and dew. - C. Transpiration (Matches 2): This is a biological process involving the loss of water vapour from the aerial parts of plants, mainly through stomata in the leaves. It is essentially evaporation from plant surfaces. - D. Infiltration (Matches 3): This refers to the downward entry of water from the land surface into the soil or porous rock. This process is crucial for recharging groundwater aquifers and sustaining soil moisture. Key Takeaway: The water cycle is driven by Evaporation (liquid to gas), Condensation (gas to liquid), Transpiration (biological release), and Infiltration (seepage into the ground).

Solution

Correct Option

The correct option is

A-1, B-4, C-2, D-3

Explanation

The fundamental processes within the hydrological cycle (water cycle). These processes facilitate the continuous movement and phase changes of water across the atmosphere, lithosphere, and biosphere.

Detailed Matching

A. Evaporation (Matches 1): This is the physical process by which water changes from a liquid state to a gaseous state (water vapour). It occurs when heat energy breaks the bonds holding water molecules together, primarily from the surfaces of oceans, lakes, and soil.
B. Condensation (Matches 4): This is the process where water vapour in the air cools and changes back into liquid water droplets. It is responsible for the formation of clouds, fog, and dew.
C. Transpiration (Matches 2): This is a biological process involving the loss of water vapour from the aerial parts of plants, mainly through stomata in the leaves. It is essentially evaporation from plant surfaces.
D. Infiltration (Matches 3): This refers to the downward entry of water from the land surface into the soil or porous rock. This process is crucial for recharging groundwater aquifers and sustaining soil moisture.

Key Takeaway: The water cycle is driven by Evaporation (liquid to gas), Condensation (gas to liquid), Transpiration (biological release), and Infiltration (seepage into the ground).

More from Chapter 1: Water

With reference to the process of evaporation in the water cycle, consider the following statements: 1. Evaporation of water can take place even in the shade. 2. Water vapour formed during evaporation carries dissolved salts with it into the atmosphere. 3. Warm air can provide the necessary heat for evaporation to occur in shaded areas. Which of the statements given above is/are correct?

medium

Which process explains the drying of a wet surface even in the absence of direct sunlight?

easy

Consider the following statements regarding the loss of water by plants: 1. Plants release water into the air through the process of condensation. 2. Plants release a significant amount of water into the air. 3. Transpiration plays a role in adding water vapour to the atmosphere. Which of the statements given above is/are correct?

medium

With reference to the sources of water vapour in the atmosphere, consider the following statements: 1. Water vapour is added to the air exclusively by the evaporation of water from oceans and lakes. 2. Evaporation from water bodies is a major source of water vapour in the air. 3. Transpiration by plants does not contribute to the water vapour in the air. Which of the statements given above is/are correct?

easy

Consider the following statements regarding the rate of evaporation: 1. Evaporation is generally a slow process. 2. Evaporation occurs at the same rate in sunlight and in the shade. 3. Heating water on a burner increases the rate of evaporation. Which of the statements given above are correct?
