water use and pollution

Total water

97 % salt 3% fresh

• Fresh water distribution:

• Frozen: 70%

• Underground: 29%

• Lakes and Rivers: <1%

What does deforestation do to the water cycle?

(think what process above would be greatly affected?)

Deforestation disrupts the water cycle by reducing evapotranspiration, increasing runoff, and decreasing infiltration, which can lead to decreased rainfall and increased erosion.

What’s watershed

A watershed is an area of land that drains into a common body of water, such as a river, lake, or ocean.

As Atlanta continues to grow, and water use goes up, how does that affect the people that live in South Georgia?

Increased water use in Atlanta can reduce water availability for people in South Georgia, potentially leading to water shortages and conflicts over water resources.

What is the largest river basin in the United States?

The largest river basin in the United States is the Mississippi River Basin.

What is a recharge zone of an aquifer and why is it important?

recharge zone is an area where water infiltrates into an aquifer. It is important because it replenishes the groundwater supply.

What is a saltwater intrusion?

Saltwater intrusion is the movement of saline water into freshwater aquifers,

which can contaminate the freshwater supply.

What is a cone of depression

cone of depression is a localized lowering of the water table around a pumping well.

1. If an "upstream" country builds a series of dams, what would happen to the "downstream" country?‼

The downstream country may experience reduced water flow, altered water quality, and potential disruptions to ecosystems and agriculture.

Define "point source" pollution and give three examples.

Point source pollution is pollution that comes from a single, identifiable source.

Examples include:

1. Industrial discharge pipes

2. Sewage treatment plants

3. Oil spills from a specific tanker

1. Define "non-point source pollution" and give three examples.

Non-point source pollution is pollution that comes from many diffuse sources.

Examples include:

1. Agricultural runoff

2. Urban stormwater runoff

3. Atmospheric deposition

Heavy Metal-

Pollution by metals like mercury and lead, leading to neurological and developmental problems.

Nutrient

(Phosphorus/nitrogen):

Excessive nutrients causing

eutrophication, leading to algal blooms and oxygen depletion.

Acid

Acid rain from sulfur and nitrogen oxides, leading to acidification of lakes and damage to ecosystems.

Sediment:

Excessive soil particles in water, leading to reduced light penetration and habitat destruction.

1. What is eutrophication? And what causes it?

the excessive enrichment of a body of water with nutrients, leading to increased plant growth and decay. It is caused by runoff from fertilizers, sewage, and detergents.

What are two main causes of water pollution?

Two main causes of water pollution are industrial discharge and agricultural runoff.

1. List three dangers to sea life as the result of plastic trash accumulating in the ocean.

1. Entanglement of marine animals

2. Ingestion of plastic by wildlife

3. Habitat destruction
