Another name given to the water cycle 

What is Hydrological Cycle?

100

The introduction of chemical or biological materials into the water. 

What is Water pollution?
100

The layer of the atmosphere where ozone is found.

What is the stratosphere?

100

Process where plants convert CO₂ into glucose.

What is Photosynthesis? 

100

 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? 

200

This process converts liquid water to vapor due to heat from the sun

What is Evaporation?

200

Excess nutrients causing algal blooms and low dissolved oxygen.

What is Eutrophication?

200

Ozone protects life on Earth by absorbing this harmful radiation.

What is ultraviolet (UV) radiation?

200

The process by which animals and plants release carbon dioxide back into the atmosphere.

What is Respiration?

200

The enhanced greenhouse effect results from an increase in this type of radiation trapped in the atmosphere.

What is Infrared Radiation? 

300

The stage where water vapor cools and forms clouds.

What is Condensation?

300

Cloudy or murky water caused by suspended particles.

What is turbidity? 

300

When a molecule absorbs UV light and that energy causes the molecule to split into smaller parts, usually atoms or radicals.

What is Photodissociation 

300

This long-term carbon store is formed from dead organisms buried and compressed over millions of years.

What is Fossil Fuels?

300

 The melting of glaciers contribute to this major effect of global warming.

What is Sea- level rise?

400

The process where heavier particles settle at the bottom of a tank.

What is sedimentation?

400

This process in water treatment involves adding chemicals to clump together fine suspended particles.

What is flocculation? 

400

A main effect of ozone depletion on humans is an increased risk of this.

What is skin cancer or cataracts?

400

Increasing atmospheric CO₂ causes this change in oceans, making them more acidic and affecting marine life.

What is Ocean Acidification? 

400

Produced by bacterial decomposition in marshes, rice paddies, and the digestive systems of ruminant animals (e.g., cows).

What is Methane?

500

This method uses membranes and electrical potential to separate ions from water.

what is electrodialysis? 

500

This is the process of removing salt and minerals from seawater to make it drinkable.

What is Desalination? 

500

Used in refrigerants and aerosols.

What is Chlorofluorocarbons (CFCs) 

500

Burning fossil fuels returns carbon to the atmosphere through this process

What is Combustion? 

500

It is present in low concentrations and is very effective at trapping heat.

What is Carbon dioxide?
