Revolution VS Rotation By: Ulrich Torres

Rotation of The Earth • Rotation means “to spin”. • Earth rotates on its axis, an imaginary line going through the center of the earth from the north pole to the south pole. • Earth completes 1 rotation every 24 hours. • The Earth rotates counterclockwise. • The speed of rotation is 24, 855 miles/24 hr or 1, 038 miles/hr.

Revolution • Revolution (Orbit) means “to go around something” • It takes the Earth 1 year (365. 25 days = 8, 766 hrs) to revolve around the sun. • The Earth also revolves counterclockwise around the sun. • The speed of the Earths revolution is about 18 miles per second.

Summary • Rotation - The Earth spinning on its own axis • Rotation speed- 24, 855 miles/24 hr or 1, 038 miles/hr • Revolution – The Earth revolves (spins around) the sun • Revolution speed -18 miles/sec.

Fun Facts • We are all moving at a speed of up to 1, 674 km/hr thanks to the earths rotation. • Due to gravitational interactions with the moon, the Earth’s rotation is gradually slowing down. • Around the beginning of Earths formation a day lasted about 13 or 14 hours instead of 24. • Every year the Moon moves about 1. 6 inches out from its orbit around the earth. • You are carried about 18 miles through space every second due to the orbital motion of the Earth.
