Water, Silicon, & Phosphorus Cycles

Front

What is eutrophication?

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients (like phosphorus), leading to excessive growth of algae and depletion of oxygen, harming aquatic life.

Front

What is precipitation?

Back

Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from the atmosphere to the ground.

Front

What role does silicon play in marine ecosystems?

Back

Silicon enhances the structural integrity of marine animals, particularly in the formation of shells and skeletons.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water within the Earth and atmosphere, involving processes like evaporation, condensation, and precipitation.

Front

How does runoff contribute to the phosphorus cycle?

Back

Runoff brings phosphorus from land into waterways, often from fertilizers and waste, which can lead to eutrophication.

Front

Define the term 'water cycle'.

Back

The water cycle refers to the process of water circulating through the environment, including evaporation, condensation, and precipitation.

Front

What is the main consequence of excess phosphorus in water bodies?

Back

The main consequence is eutrophication, which can lead to harmful algal blooms and oxygen depletion.

Front

What is the process of evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas (water vapor) due to heat.

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming clouds.

Front

What is the significance of silicon in ocean ecosystems?

Back

Silicon is crucial for the growth of diatoms, a type of phytoplankton that forms the base of the marine food web.
