Final answer:
Earth's atmosphere supports life by keeping it warm through the greenhouse effect.
Step-by-step explanation:
One way that Earth's atmosphere supports life is by keeping Earth warm. The atmosphere absorbs and retains heat from the sun, creating a stable temperature range suitable for life. This is achieved through the greenhouse effect, where certain gases in the atmosphere trap heat and prevent it from escaping into space. Without this, the planet would be too cold for life to thrive.
