Water Pollution

Emissions from factories and vehicles, like Nitric Acid and Carbon Dioxide, are released into the air. They can travel long distances before falling to the ground during the water cycle.

What is this type of precipitation called?

• Dead Zone

• Aquifer

• Acid Rain

• Effluent

The pollution that passes directly into water from farms, factories, and cities can be in the form of:

• Chemicals

• Sediments

• Fertilizers

• All of the above

What are DEAD ZONES in regards to water pollution?

• Sewage and runoff from farms can contain nutrients that cause excessive aquatic plant growth ultimately removing all oxygen from the water inhibiting life

• Pollution that percolates into the ground getting into the roots of trees and other organisms inhibiting growth of plants and animals on the land above

• Areas on land where there is no cell phone coverage due to a lack of GPS satellites orbiting our planet every day

• Emissions from cars and factories end up in the air killing off all birds and life in the skies

Does sewage pollute water?

• No, it actually helps remove sludge from our toilets into the ocean

• No, the water will dilute it and wash it away, especially in a bay

• Yes, it increases bacteria and viruses in the water that can infect swimmers and animals

• Yes, it removes excess carbon dioxide and nitric acid from the water

The type of ground water that is most protected from pollution due to a strong barrier is stored in:

• Bottles

• Unconfined Aquifers

• Confined Aquifers

• Subsidience

Rocks fall in on themselves when large amounts of groundwater have been withdrawn from certain types of rocks.

What process is this?

• Aquifer

• Water Table

• Impermeable Layer

• Subsidence

Spaces within aquifers that are completely filled with fresh water are called:

• Virtual Water

• Zone of Saturation

• Water Footprint

• Surface Runoff

The process of REMOVING dissolved salt from ocean water or from brackish water in aquifers or lakes is known as:

• Fracking

• Oil Spill

• Desalination

• Resolution

California receives a large portion of its freshwater supply from the Colorado River in Arizona, despite having a whole ocean on their western boundary.

Which major barrier is associated with desalination of ocean water that prevents California from using ocean water?

• Would cause flooding

• No technology

• Laws prevent them

• Process is too costly

Which of the following is used to capture and store the surface runoff from a river's watershed?

• Reservoir

• Snowpack

• Desalination

• Subsidence
