Question

Arrange the process of the water cycle in correct order, starting with the heat from the Sun.

Answer 1

The following is the correct order starting from the heat of the Sun 4, 2, 6, 1, 5 and 3.

Starting with the heat from the sun (4), the process of evaporation takes place (2). In this process, heat from the Sun evaporates water from the rivers, oceans, lakes, ice, and soil into water vapor. After this the process of condensation takes place (6), in this water vapor from clouds cools down and converts back into liquid water in the form of water droplets. These water droplets remain in the air.

Then the process of precipitation takes place (1), in this, water droplets combine with air and becomes too heavy to stay in the air. Thus, they fall in the form of rain. After this runoff (5), that is, downward movement of surface water takes place under the influence of gravity. Finally, collection (3) takes place, in this water that falls as snow or rain comes back to the lakes, oceans, rivers, or any other water body.

Answer 2

The labelled diagram is attached below & the correct sequence is shown below:

4. Sun Heat - The heat of sun causes water to evaporate.

2. Evaporation- vaporization of water

6. Condensation - The conversion of water vapours from gaseous to liquid state.

1. Precipitation - water falls from clouds in the form of rain, snow or sleet.

5. Run off - The surface water is a major part of the collected water, flows from top of any surface (form rain, snow etc)

3. Collection of water - The rain water is collected.
