Laura,
I’d try to be very careful with the language around “The Earth moving” and distinguish between orbiting the Sun (which it does every year) and rotating on its own axis, which it does every day.
During one rotation, the Earth moves 1/365th of its orbit around the Sun. It is the rotation that gives us day and night. At the same time, we move a little bit around the Sun, which after a few months gives us a change in season.
This What if from the creator of XKCD has some really fun numbers in an answer to a ‘what if’ question that include the speed of the Earth’s surface.
and this video answers the ‘what if the Earth suddenly stopped spinning?’
