Which of the following are wasteful uses of water? SELECT ALL THAT APPLY a Decorative fountains in dry areas b Drip irrigation that keeps water near the ground c Spray irrigation that throws water into the air d Washing cars

## Step 1<br />The problem asks us to identify which of the given options are wasteful uses of water. We need to consider the efficiency of water usage in each option.<br /><br />## Step 2<br />Option a, decorative fountains in dry areas, is a wasteful use of water. This is because these fountains often run continuously, even when there is a shortage of water. The water used in these fountains could be used for more essential purposes.<br /><br />## Step 3<br />Option b, drip irrigation that keeps water near the ground, is not a wasteful use of water. This method of irrigation is designed to minimize water wastage by delivering water directly to the roots of the plants, reducing evaporation and runoff.<br /><br />## Step 4<br />Option c, spray irrigation that throws water into the air, can be wasteful. This method can lead to water loss through evaporation and runoff, especially if not properly managed.<br /><br />## Step 5<br />Option d, washing cars, can be wasteful if done using a hose without a nozzle or if the water is left running continuously. This can lead to significant water wastage.
