What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, thus warming the planet.

Front

How does an increase in greenhouse gases affect global temperatures?

Back

An increase in greenhouse gases leads to less heat escaping from the Earth's atmosphere, causing global temperatures to rise.

Front

What are nonpoint sources of pollution?

Back

Nonpoint sources of pollution are diffuse, widespread sources of pollution that are difficult to control, such as runoff from agricultural fields.

Front

Why are nonpoint sources of pollution harder to regulate than point sources?

Back

They originate from multiple, diffuse sources rather than a single, identifiable source, making them more challenging to manage.

Front

What role do algae play in aquatic ecosystems?

Back

Algae produce oxygen through photosynthesis and serve as a food source for various aquatic organisms.

Front

What happens to oxygen levels in water when algae proliferate?

Back

Excessive algae growth can deplete oxygen levels in water, leading to hypoxic conditions harmful to aquatic life.

Front

What is the impact of deforestation on carbon dioxide levels?

Back

Deforestation increases carbon dioxide levels in the atmosphere as trees that absorb CO2 are removed.

Front

How does solar energy use affect greenhouse gas emissions?

Back

The use of solar energy does not increase greenhouse gas emissions, as it is a clean, renewable energy source.

Front

What is the relationship between global warming and climate change?

Back

Global warming refers to the increase in Earth's average surface temperature, while climate change encompasses broader changes in climate patterns, including temperature, precipitation, and wind.

Front

What are the primary greenhouse gases?

Back

The primary greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.
