Answer:
Agriculture used about 59 km3 of freshwater in 2000 (86 percent of total use). All drainage water in Upper Egypt, south of Cairo, flows back into the Nile and the irrigation canals; this amount is estimated at 4 km3/yr. Drainage water in the Nile Delta is estimated at 14 km3/yr.

Answer: Sand Dunes Stabilization
Explanation:
Sand Dunes Stabilization is the process of engaging in actions that keep Sand Dunes in place to protect their Natural Habitat status.
Two such actions can be useful in this scenario.
1. Putting up Vegetation
- The roots of plants can help anchor soil which will reduce the rate at which it is blown around by wind or carried off by water. This will therefore reduce the rate at which sand dunes lose sand.
2. Putting up Wooden Fences
- Putting up Wooden Fences would also help reduce the rate sand dunes end up on roads for the simple reason that it would stop some of them from being blown by the wind and in so doing keep them where they are supposed to be.

Answer: C.
Air masses that are hot and dry, and are responsible for heatwaves of summer in the western half of the United States.
Explanation: Air masses have fairly uniform temperature and moisture content in the horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties. The properties of air masses are determined by the underlying surface properties where they originate.
Air that stands over the Caribbean Sea, for example, becomes a warm, humid maritime tropical air mass, while air that lies in the Arctic regions of northern Canada takes on the cold and dry characteristics of its surroundings and becomes a continental polar air mass.
