Fresh and Saltwater Systems - Science 8 Study Notes

Flashcards about Fresh and Saltwater Systems.

Potable Water

Drinking water from surface and ground sources that has been treated to meet state and federal standards, making it safe for human consumption.

Evaporation

A water purification technique where water is heated to separate salt/sediment, forming water vapor that replenishes freshwater supply.

Distillation

A water purification technique that heats saltwater to separate water from salt, then condenses water vapor to collect fresh water.

Reverse Osmosis

A water purification technique that uses pressure to force water through a membrane, moving water from areas of low concentration to high concentration.

Water Quality Monitoring

Assessment of water based on cloudiness, water movement, biodiversity support, temperature, pH levels, and dissolved oxygen.

Waste Pollution

Type of water pollution that creates excessive algae growth.

Chemical Pollution

Type of water pollution where harmful chemicals contaminate water, making it undrinkable.

Thermal Pollution

Type of water pollution involving warm water dumping, which disrupts ecosystem temperature balance.

Acid Rain

Type of water pollution where air pollutants enter the water cycle, creating acidic precipitation.
