The two motions that cause orbiting are gravity and free fall. Take an orbiting space shuttle for example. The shuttle is in free fall because gravity pulls down on it. The shuttle's path would be straight if not for gravity pulling down on it. The shuttle moves forward at a constant speed and gravity pulls down on it, so the path of the shuttle is curved.
Meteors are pieces of rocky or metallic material that enter Earth's atmosphere and burn up due to friction. They do not move in an orbit like a satellite because they do not have the velocity needed to stay in orbit around Earth. Instead, they move in a trajectory that intersects with Earth's atmosphere.
the moon doesent orbit the sun, the earth orbits the sun and the moon orbits the earth.
No. Earth's orbit is NOT tilted. Earth orbits the Sun in the same plane as the rest of the planets. What IS tilted is Earth's axis of spin (as compared to the plane of its orbit), It is this tilt of this axis that causes the seasons as Earth makes its annual orbit of the Sun.
Gravity keeps satellites in orbit. The closer you are to the Earth, the faster you have to go to maintain your orbit. At low Earth orbit, the altitude of the Space Station, you make an orbit every 90 minutes. At the Moon's distance you need over 27 days to go around the Earth. In-between there is an altitude which matches the rate of the Earth's rotation. Many satellites orbit at this altitude.

Nothing does.Simply because the moon does not orbit the sun.The moon orbits Earth, not the sun. And Earth orbits the sun.Gravity is what causes planets and moons to orbit.
It causes our seasons.
Elliptical.

Gravity
Our Earth is not in a falling orbit.
Gravity. Things naturally travel in a straight line unless another force acts on them. The moon would travel in a straight line but is dragged down by the gravity of the earth. This constant acceleration towards the earth causes it to orbit the earth in a curve.
the moon doesent orbit the sun, the earth orbits the sun and the moon orbits the earth.
The force of gravity causes the moon to orbit the Earth, and the Earth to orbit the sun.
