[Ans] When the moon formed, how many hours long was a day on Earth?

Step 1 : Introduction to the question "When the moon formed, how many hours long was a day on Earth?"



... How long was a day? 
When was the earth created? Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen. History of Earth - 

How long is a day on the earth? You're right that a "sidereal" day is about 23 hours, 56 minutes, 4 seconds. But this is not a day in the everyday sense. A sidereal day is how long it takes the earth (on average) to make one rotation relative to the faraway stars and other galaxies in the sky.

How long did it take for the Earth to form? The Earth forms. The Earth is thought to have been formed about 4.6 billion years ago by collisions in the giant disc-shaped cloud of material that also formed the Sun. Gravity slowly gathered this gas and dust together into clumps that became asteroids and small early planets called planetesimals.




Step 2 : Answer to the question "When the moon formed, how many hours long was a day on Earth?"



5.5 hours:


When the moon formed billions of years ago, scientists estimate that the Earth revolved on its axis once every 5.5 hours. That means a full day on planet Earth was a meager 5.5 hours. Because of the moon's tidal gravitational pull, the Earth began slowing down, and it continues slowing down today. A day on Earth - sunrise to sunrise - gets longer by about one second each year. The gravitational pull of the moon causes a rise and fall of the ocean surface, what we call the oceanic tide. It also pulls on the Earth's crust, and that pulling, combined with the pull on the oceans, slows the Earth's rotation. Source: NBCNews.com
