APES Water Resources

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
• land subsidence
• sinkholes
• drought

The term subsidence refers to

• failure of the groundwater supply
• accumulation of silt behind a dam
• sinking of ground when water has been withdrawn
• intrusion of salt water into a freshwater aquifer

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

Use Figure provided. Household per capita daily use of water is greatest in

• Cambodia

• Australia

• Canada

• The United States

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
