Apart from believing what scientists tell us, watching the stars is positive proof. This is especially apparent when viewing a time delayed sequence of pictures taken with the Pole Star in the centre (in the northern hemisphere). Though there is slight movement of the Pole Star, all other stars move round the Pole Star and show as curved lines of light.
The day/night cycle results from the Earth rotating.
by the earth rotating around the sun while the moon is rotating around the earth.
no, it's the Earth that is constantly rotating around the Sun
The rotation causes the days, 24 hour periods of light and dark based on your location on the Earth. The rotation is important because without rotation of the earth, we would not as easily be able to tell, or keep track of time. What we consider to be the passage of time- 1 minute, 1 hour, 1 day, is all relative to how fast the Earth is rotating. Now as the Earth is rotating, it also is at a very specific tilt. The Earth is at a tilt of 23.5 degrees, meaning when it is rotating around the sun it isn't straight "up and down". The tilting is important because it gives us seasonal variation. The tilt is what causes the seasons to change. Which is important to humans, because it dictates climate in certain areas, growing seasons in agriculture, climate for survival for many animal species, and so on.
earth is approximately rotating at 66 and a half degrees
Nothing will happen because of the gravity
because earth is rotating around itself while revolving around the sun
Any object that rotates has a tendency to continue rotating.
Nicolaus Copernicus was the first to formulate the theory that placed the Earth and other planets rotating around the Sun.
because earth is rotating and revolving
No. As far as scientists can tell, humans are the smartest animals on Earth. Crows and ravens are believed to be the smartest birds.
we'd all die because we would feel earth stop rotating . because we can only feel acceleration and stopping
