  4. Subsurface
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Drip irrigation is a form of irrigation that saves water and fertilizer by allowing water to drip slowly to the roots of many different plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. It is done through narrow tubes that deliver water directly to the base of the plant. It is chosen instead of surface irrigation for various reasons, often including concern about minimizing evaporation.

Drip irrigation is used in farms, commercial greenhouses, and residential gardeners. Drip irrigation is adopted extensively in areas of acute water scarcity and especially for crops and trees such as coconuts, containerized landscape trees, grapes, bananas, pandey, eggplant, citrus, strawberries, sugarcane, cotton, maize, and potatoes.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Never try to walk or swim through flowing water. Don’t go for tour in sea during flooding. If flowing water is above your ankles, then stop and turn around and go another way. If it is moving swiftly, water 6 inches deep can knock you off your feet. Be aware that people have been swept away wading through flood waters.

Turn off utilities at the main switches or valves if instructed to do so. Disconnect electrical appliances. Do not touch electrical equipment if you are wet or standing in water. Avoid floodwaters; water may be contaminated by oil, gasoline, or raw sewage. Water may also be electrically charged from underground or downed power lines.

In what ways students can respond to drought?

  1. Harvest rainwater at home and school

  2. Plant trees

  3. Conserve water

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Harvesting rainwater at home and school generally help in using it up in times of scarcity.

Trees, especially drought-tolerant, native species, also provide critical services that directly attack some of the consequences of drought. Native trees send out deep, water-seeking roots into the soil to tap into local groundwater and draw it to the surface.

Conserving water makes us use the water the less so that water is not wasted and could put in use during droughts.
