Water Cycle and Water purification
Another name given to the water cycle
What is Hydrological Cycle?
The introduction of chemical or biological materials into the water.
The layer of the atmosphere where ozone is found.
What is the stratosphere?
Process where plants convert CO₂ into glucose.
What is Photosynthesis?
Is a natural warming process that keeps the Earth’s surface and lower atmosphere at a temperature suitable for life.
What is the greenhouse effect?
This process converts liquid water to vapor due to heat from the sun
What is Evaporation?
Excess nutrients causing algal blooms and low dissolved oxygen.
What is Eutrophication?
Ozone protects life on Earth by absorbing this harmful radiation.
What is ultraviolet (UV) radiation?
The process by which animals and plants release carbon dioxide back into the atmosphere.
What is Respiration?
The enhanced greenhouse effect results from an increase in this type of radiation trapped in the atmosphere.
What is Infrared Radiation?
The stage where water vapor cools and forms clouds.
What is Condensation?
Cloudy or murky water caused by suspended particles.
What is turbidity?
When a molecule absorbs UV light and that energy causes the molecule to split into smaller parts, usually atoms or radicals.
What is Photodissociation
This long-term carbon store is formed from dead organisms buried and compressed over millions of years.
What is Fossil Fuels?
The melting of glaciers contribute to this major effect of global warming.
What is Sea- level rise?
The process where heavier particles settle at the bottom of a tank.
What is sedimentation?
This process in water treatment involves adding chemicals to clump together fine suspended particles.
What is flocculation?
A main effect of ozone depletion on humans is an increased risk of this.
What is skin cancer or cataracts?
Increasing atmospheric CO₂ causes this change in oceans, making them more acidic and affecting marine life.
What is Ocean Acidification?
Produced by bacterial decomposition in marshes, rice paddies, and the digestive systems of ruminant animals (e.g., cows).
What is Methane?
This method uses membranes and electrical potential to separate ions from water.
what is electrodialysis?
This is the process of removing salt and minerals from seawater to make it drinkable.
What is Desalination?
Used in refrigerants and aerosols.
What is Chlorofluorocarbons (CFCs)
Burning fossil fuels returns carbon to the atmosphere through this process
What is Combustion?
It is present in low concentrations and is very effective at trapping heat.
What is Carbon dioxide?
