WX 101: The Earth's Rotation and Movements

-

Every time you step outside you can barely recognize the Earth is moving. One of the best indications of the Earth’s movement is daylight. The Earth spins counter-clockwise on its axis, which means it spins from west to east at a speed of 1070 mph at the equator. This rotation is the reason for day and night since the Earth rotates once every 23 hours 56 minutes and 4 seconds, which is averaged to 24 hours based on sunlight.

Another fact to consider is the Earth’s orbit around the Sun. It takes the Earth 365 days to complete its rotation around the sun at a speed of 67,108 mph. That's impressive, considering how we're unable to tell from the surface.
