Front

What is reforestation?

Back

The process of planting trees in an area where forests have been cut down or degraded to help mitigate atmospheric impact.

Front

What is ocean acidification?

Back

The process by which carbon dioxide dissolves in ocean water, leading to a decrease in pH and harming marine life.

Front

Which greenhouse gas is primarily discussed in relation to climate change?

Back

Carbon dioxide.

Front

How do sunspots affect global climate?

Back

An increase in sunspots can lead to higher global temperatures.

Front

What are greenhouse gases?

Back

Gases in the atmosphere that trap heat, contributing to the greenhouse effect.

Front

What is the greenhouse effect?

Back

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

Front

What role do fossil fuels play in atmospheric changes?

Back

Burning fossil fuels releases carbon dioxide and other greenhouse gases, contributing to climate change.

Front

What is the impact of deforestation on the atmosphere?

Back

Deforestation increases carbon dioxide levels and reduces oxygen production, worsening climate change.

Front

What is the significance of carbon sinks?

Back

Natural systems, like forests and oceans, that absorb more carbon dioxide than they release, helping to mitigate climate change.
