What regulates the temperatures on Earth and protects it from harmful UV rays and meteors?

A. Earths magnetic field

B. Earths atmosphere

C. Earths moon

D. Earths ocean's

Answer: B. Earth's atmosphere

Explanation: You may think that it's the magnetic field because it talks about harmful UV rays. The field doesn't stop them. It only stops solar wind. The atmosphere scatters the UV rays to protect us. It also burns up meteors that attempt to hit Earth.

[ B. Earths atmosphere. ]

The atmosphere regulates the temperatures on Earth and protects it from harmful UV rays and meteors. In the stratosphere, it is heated by the ultraviolet radiation of the sun. If it weren't for the stratosphere, the rays from the sun would be deadly. In the troposphere, all of Earths weather occurs in it. The air in the troposphere is the densest as it contains 3/4 of all mass in the entire atmosphere.

Best of Luck!
