In the semi arid regions of china, the country's inhabitants have practiced water harvesting for generations. water harvesting is the process of collecting rainfall and/or runoff for later use. how does this water conservation method the environment?

a) water harvesting causes drought-like conditions the rest of the year.
b) harvesting water during the rainy season has damaged the ecosystem by killing some of the organisms.
c) by collecting run off during the rainy season for future irrigation increases the agricultural production.
d) run off is one of the main sources of drinking water so there is a shortage of drinking water the remaining part of the year.

C) By collecting run off during the rainy season for future irrigation increases the agricultural production

Explanation:

Water harvesting is a process of collection of rain water by using special water storing systems. This water storage practice helps during the scarcity of water like in dry summer seasons and in conditions of drought. Such water can be treated with filters to make it potable for drinking. But generally the water is used for the purpose of irrigation in the agricultural field and household sanitary requirements.

On the basis of the above description, By collecting run off during the rainy season for future irrigation increases the agricultural production is the correct option.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
