Human Impact

Front

What is the relationship between carbon dioxide concentrations and global temperatures?

Back

As carbon dioxide concentrations increase, global temperatures increase.

Front

How does global warming contribute to rising sea levels?

Back

Global warming causes sea levels to rise by melting glaciers and ice caps.

Front

Which level of the food web contains the highest concentration of chemical pollutants?

Back

Tertiary consumers contain the highest concentration of chemical pollutants.

Front

What does conserving resources mean?

Back

Conserving resources means protecting the resource so it does not run out.

Front

How does deforestation affect global warming?

Back

Deforestation contributes to global warming because fewer trees mean less CO2 is absorbed through photosynthesis.

Front

What is global warming?

Back

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which greenhouse gases trap heat in the atmosphere, keeping the Earth warm.

Front

What is the impact of melting ice caps on ecosystems?

Back

Melting ice caps can lead to habitat loss for polar species and contribute to rising sea levels, affecting coastal ecosystems.

Front

What role do trees play in carbon dioxide absorption?

Back

Trees absorb CO2 during photosynthesis, helping to reduce greenhouse gas concentrations in the atmosphere.
