๐ Topic Summary
Greenhouse gases are gases in Earth's atmosphere that trap heat. This process, known as the greenhouse effect, warms the planet and makes it habitable. However, increased concentrations of these gases, primarily from human activities, can lead to excessive warming and climate change. Common greenhouse gases include carbon dioxide ($CO_2$), methane ($CH_4$), nitrous oxide ($N_2O$), and fluorinated gases.
Understanding the sources, sinks, and impacts of greenhouse gases is crucial for developing effective strategies to mitigate climate change. This worksheet will help you practice key concepts related to greenhouse gases.
