the answer is when the earth's move on it axis the movement of picking objects near the sun near the orbit
Yes. Clearly the Earth orbits around the Earth.
Mass & Velocity .
Gravity and Inertia
Farmers used crop rotation to keep the earth fertile.
Nitrogen levels and surface radiation.
At first they sailed around coastlines, then worked ot how to use the polar star to keep their bearings when away from land.
Yes. Clearly the Earth orbits around the Earth.
A compass tells sailors which direction they are going in (North, South, East, or West). This helps the sailors not to get lost and to keep on track to their destination.
No.
Yes; the sun's gravity keeps the Earth orbiting around it.
the earth's gravitational pull is just strong enought to keep it in orbit, but not strong enought, at that distance, to pull it back to earth
Its what keep us stuck to earth, and keeps the earth moving around the sun, for a start.
The earth will keep revolving around the sun until the sun dies out or earth is hit by a really big asteroid and knocks it out if its orbit.
Sparrows are (I should say "were") symbolic for sailors that have logged 5000 nautical miles at sea. These are blue swallows as far as tradition goes. The others are just new schooler trying to bring back some old school with there own twist. I personally have one tattooed under each arm showing for my two trips around the world. For you other real sailors keep the tradition and have some pride in your service. Answer I have them on my back shoulders for having sailed across both hemispheres. They represent a sailor's safe return home from sea. Sailors would see the sparrows and follow them to the shore.
because it is pushed by aliens around the earth
Mass & Velocity .
The moon, satellites, international space station, and everything else orbiting the earth.
