Answer: Gravity made the dust and gas in the nebula collide, flattening these materials into a disk.
Explanation: The nebula theory is a scientific explanation of how the planets and our solar system were formed. It suggests that our solar system was formed more than 4 billion years ago due to the effect of gravity on a cloud of gas and dust which were flattened into a disk. The gravity was so great that the matter in the nebula were made to collide against each other until they were compacted to form our sun.

Answer:
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.
