What two things does the sun provide for earth?

Location (orbit) and energy.


What is the two things that keep the earth in its orbit around the sun?

The two things that keep the Earth in its orbit around the Sun are the gravitational pull of the Sun, which creates a centripetal force that keeps the Earth moving in a curved path, and the inertia of the Earth, which causes it to continue moving in a straight line unless acted upon by an external force. Together, these two forces balance each other to maintain the Earth's orbit.


Name two things the earth atmosphere helps keep out?

The Earth's atmosphere helps to block harmful ultraviolet radiation from the sun, protecting living organisms from its damaging effects. It also blocks most meteoroids from reaching the Earth's surface, burning them up as they enter the atmosphere.


What two things does the sun provide for living things on earth?

The sun provides light for photosynthesis, the process by which plants make their own food. This process forms the basis of the food chain, sustaining all life on Earth. Additionally, the sun also provides warmth, creating a stable climate that allows for the survival of various organisms.


What two things are found on the moon and are not found on earth?

The study of the few samples of rock returned from the moon with the Apollo crews strongly suggests that the moon and the earth are made of pretty much the same stuff. One theory for the formation of the moon, and arguably the best one so far, is that something really, really big slammed into the earth early in the formation of the planet. Whatever it was represented a good fraction of the mass of the earth, and it was large enough to "crash into" and then "tear away" from the earth, leaving both bodies molten and able to reform under their own gravity. As to what two things are found on the moon that are not found on earth, there is a lot of geological similarity between the two bodies. If we just consider two obvious characteristics, the two things that stand out about the moon, at least as compared to earth, are its lack of an atmosphere and its low(er) gravity.
