Question

Quizplus · Accepted Answer

The Earth's atmosphere helps to reduce ultraviolet radiation, trap solar heat, and regulate climate, making the planet habitable for life. It does not generate Earth's magnetic field (which is caused by the planet's molten core) or gravitational field (which is caused by the planet's mass). While it may serve as a barrier to protect us from some types of radiation, there is no evidence to suggest that it can prevent alien invasion.
