APES Water

The geological layer, consisting of underground caverns and porous layers of sand, gravel, or bedrock, where groundwater flows, is called

• zone of saturation
• aquifer
• the water table
• surface water

Throughout the world, the majority of water is used for

• irrigation
• industrial uses
• humans and animals
• cooling towers of power plants

Withdrawing too much water from an aquifer can cause all of the following except

• freshwater contaminated with saltwater

• cone of depression

• sinkholes

• drought

One method of desalination uses high pressure to force saltwater through a membrane filter. This method is called

• diffusion
• distillation
• reverse osmosis
• active transport

Where do we typically see saltwater intrusions into freshwater aquifers?

• On the great plains

• In the mountainous regions

• In coastal areas

• Along rivers

Desalination is

• removing salt from water
• removing oil from water
• removing toxic chemicals from water
• adding salt to water

Landscaping with plants that dont require much water is called

• xeriscaping
• zenoscaping
• hydroscaping
• terrascaping

The disadvantage of desalination water is that...

• It is expensive and produces briny wastewater

• It can be used in areas with little freshwater

• It produces water that is not safe to drink.

• It is not a real thing.

How has the diversion of water, as in the case of the Aral Sea, affected their original source of water?

• It left behind plains covered with salts and toxins.

• 90% of the volume has been lost.

• Fisheries have collapsed, causing an economic disaster

• All of the above.

What is the most effective type of irrigation?

• center pivot method

• flood irrigation

• drip irrigation

• using sprinklers
