1. True - Greenhouse gases absorb infrared radiation. This is a fundamental characteristic of greenhouse gases. They absorb and emit radiant energy within the thermal infrared range, contributing to the greenhouse effect.

2. False - Greenhouse gases do not make up 20% of Earth's atmosphere. They actually make up a very small percentage. The most abundant greenhouse gas, water vapor, only makes up approximately 1-4% of the atmosphere. Other greenhouse gases like carbon dioxide and methane are present in even smaller amounts.

3. True - Water vapor is a greenhouse gas. It is the most abundant greenhouse gas in the atmosphere and contributes to the natural greenhouse effect significantly.

4. True - Greenhouse gases emit infrared radiation. After absorbing infrared radiation, these gases re-emit the energy, some of which goes out into space and some of which returns to the Earth's surface. This process helps to warm the Earth's surface and lower atmosphere.
