Active Reading
Section: Water Use and Management
Read the passage below and answer the questions that follow.
Industry accounts for 19 percent of water used in the world. Water is used to manufacture goods, to dispose of waste, and to generate power. The amount of water needed to manufacture everyday items can be astounding. For instance, nearly 1,000 L of water are needed to produce 1 kg of aluminum, and almost 500,000 L of water are needed to manufacture a car. Vast amounts of water are required to produce computer chips and semiconductors.
Most of the water that is used in industry is used to cool power plants. Power-plant cooling systems usually pump water from a surface water source such as a river or lake, carry the water through pipes in a cooling tower, and then pump the water back into the source. The water that is returned is usually warmer than the source, but it is generally clean and can be used again.

8.water table; saturated
9. A water table has peaks and valleys like the land above it. It is not flat like a dining table.
10.A water table in a wet region is likely to be near the surface of Earth, and springs may flow out of the ground. A water table in the desert may be far below Earth’s surface.
11.It flows downhill. Underground peaks and valleys cause this movement.
12.The water table is near the surface of Earth.
