1. How many times does the Earth rotate in a day?

Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes, and 4 seconds with respect to other, distant stars

2. Does Earth’s rotation affect flight times?

If the air is not moving the same as the ground, it’s called wind, which is the primary influence on flight time. The wind is influenced by the Earth’s rotation, but the rotation doesn’t directly influence flight time

3. What if Earth stopped spinning?

If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth’s original 1100 mile per hour rotation speed at the equator. This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere

4. What is unusual about the rotating Earth pictured above?

It's spinning backwards! ( Just want to see if you are paying attention)
