Final answer:
The greenhouse effect is a biological phenomenon caused by certain atmospheric gases trapping heat from the sun, making the Earth warmer. Eunice Newton Foote was a researcher who conducted experiments and discovered the relationship between carbon dioxide and heat retention. This effect is similar to how a greenhouse traps heat for plants.
Step-by-step explanation:
The greenhouse effect is a biological phenomenon caused by certain atmospheric gases, such as carbon dioxide and methane, trapping heat from the sun and causing the Earth to be warmer than it would be otherwise.
This concept was first predicted by Eunice Newton Foote, who conducted experiments on heating different gases and concluded that an atmosphere with more carbon dioxide would result in more heat retention. The greenhouse effect is similar to how a greenhouse traps heat and is used by gardeners to create a warm environment for plants.
