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 like carbon dioxide and methane.

Front

How does the increase in human population affect natural resources?

Back

An increase in human population typically decreases the amount of natural resources available, as more people require more resources for food, water, and energy.

Front

What is the consequence of shrinking glaciers due to climate change?

Back

Shrinking glaciers contribute to rising sea levels, which can lead to coastal flooding and loss of habitat.

Front

What is eutrophication?

Back

Eutrophication is the process by which a body of water becomes overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Front

What happens to an ecosystem when a population exceeds its carrying capacity?

Back

When a population exceeds its carrying capacity, the ecosystem will degrade, leading to resource depletion and potential collapse.

Front

What are greenhouse gases?

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 greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

Front

What are the effects of climate change on weather patterns?

Back

Climate change can lead to more extreme weather patterns, including increased frequency and intensity of storms, droughts, and heatwaves.

Front

What is the role of nitrogen in eutrophication?

Back

Nitrogen from fertilizers can run off into water bodies, leading to eutrophication by promoting excessive algae growth.
