Explanation:
as Earth rotates, the moon's gravity causes the oceans to seem to rise and fall .( then also, but not as much). there is a little bite of friction between the points and the turning Earth causing the rotation to slow down just a little.
if the earth stopped spinning suddenly, the atmosphere Would Still Be in motion with the earth original 1100 Mile per hour rotation speed at the equator.
Is it informal letter or formal letter
I think the correct answer is A
