What is Eutrophication?

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen, which can harm aquatic life.

Front

What are GMOs?

Back

GMOs, or Genetically Modified Organisms, are organisms whose genetic material has been altered using genetic engineering techniques, often to enhance certain traits such as resistance to pests or improved nutritional content.

How is carbon stored on Earth?

Back

Carbon is stored on Earth primarily underground in the form of fossil fuels, as well as in the atmosphere, oceans, and living organisms.

Front

What is the Carbon Cycle?

Back

The Carbon Cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms, involving processes such as photosynthesis, respiration, and decomposition.

Front

What is the Water Cycle?

Back

The Water Cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes such as evaporation, condensation, precipitation, and infiltration.

Front

What role do plants play in the Carbon Cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter and releasing oxygen as a byproduct.

Front

What is the significance of the Nitrogen Cycle?

Back

The Nitrogen Cycle is crucial for converting nitrogen from the atmosphere into forms usable by living organisms, supporting plant growth and maintaining ecosystem health.

Front

What is a greenhouse gas?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect; examples include carbon dioxide, methane, and nitrous oxide.

Front

What is the role of decomposers in biogeochemical cycles?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for plants, thus playing a vital role in nutrient cycling.

Front

What is the Rock Cycle?

Back

The Rock Cycle is the series of processes that describe the transformation of rocks through geological time, including the formation, breakdown, and reformation of rocks.
