APES Water Review

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

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

• diffusion
• distillation
• reverse osmosis
• active transport

97 % of all water on Earth is in the oceans. Which of the following is the correct order of the Earth’s water storage compartments from largest to smallest?

• ocean, atmosphere, lakes, groundwater, rivers, ice caps

• ocean, groundwater, rivers, ice caps, atmosphere, lakes

• ocean, ice caps, groundwater, lakes, atmosphere, rivers

• ocean, lakes, ice caps, groundwater, atmosphere, rivers

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

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

Four of the following are disadvantages of dam and reservoir systems; one is not. Choose the one that is not.

• Dams and reservoirs disrupt migration of some fish.
• Dams and reservoirs displace people behind the dam
• Dams and reservoirs lead to devastating flooding if there is a failure.
• Dams and reservoirs increases downstream flooding.
