Because the Earth is round.
Miyahara points to the 27-day solar rotational period, which is the average time it takes for the sun to rotate on its axis. Since the sun consists of plasma, the equator rotates quicker than its poles. When areas of high activity, such as sunspots, face Earth, there's an increase in ...
Why is the Solar System flat? As theSolar systemrotated at a great speed it flattened out into a disk like shape with a bulge in the middle where the Sun formed. This is the same structure that was followed throughout the Universe : the shape of galaxies, the black holes even down to...
a. To cause to move around an axis or center; cause to rotate or revolve: A motor turns the wheels. b. To cause to move around in order to achieve a result, such as opening, closing, tightening, or loosening: turn the key; turn a screw. 2. To alter or control the functioning of...
Earth is rotating, turning once on its axis every day. Fortunately gravity keeps you firmly attached to the planet, and because of momentum, you don’t feel the movement – the same way you don’t feel the speed of a car going down the highway. But how fast does the Earth rotate?

. This is different from a planet’s revolution, which is the time it takes for a planet to orbit around another object (i.e. the Sun). So while it takes the Earth one day (24 hours) to rotate once on its axis, it takes one year (365.256 days) to revolve once around the Sun....
