5.

Answer 1

2. When energy from the sun reaches the Earth's atmosphere, some of it is absorbed by the Earth's surface, while the rest is reflected back into space.
3. The absorbed energy warms the Earth's surface, which then radiates heat back into the atmosphere.
4. Greenhouse gases in the Earth's atmosphere, such as carbon dioxide and water vapor, trap some of this heat and prevent it from escaping back into space, creating a natural blanket effect.
5. This retained heat, due to the greenhouse effect, helps to keep the Earth warm and suitable for supporting life.
