Who will usher in the dawn first PPT, part 2: Confirming the direction of the earth's rotation

As you drive forward in the car, look out the window. What is the direction of movement of the woods on both sides of the road?

Sitting on a swivel chair, if you turn the swivel chair clockwise, what is the direction of movement of the surrounding scenery?

The rotation direction of the swivel chair is opposite to the relative movement direction of the surrounding objects.

Sitting on the "big swivel chair" of the earth, we see the stars around the earth, such as the sun, the moon, etc., what is the direction of their movement?

We already know that the Earth spins. On the rotating earth, you can see other stars other than the earth (such as the sun, stars, etc.) rising in the east and setting in the west. This is actually the result of the relative motion between the earth and them. The direction of the earth's rotation is exactly opposite to the direction in which they move from east to west (or clockwise), which is from west to east (or counterclockwise).

The Earth rotates once per day, approximately 24 hours.
