Dear David:

Why is the earth and bowling balls round?

some what, but---------- The grammar nazi is going tohave a field day with me and my abuse of the english language -

 

Dear Young in Cincy,

They are not round, or even perfect spheres.!

The shape of the Earth is very close to that of an oblate spheroid, a sphere flattened along the axis from pole to pole such that there is a bulge around the equator.[sup][62][/sup] This bulge results from the rotation of the Earth, and causes the diameter at the equator to be 43 km larger than the pole to pole diameter.

A bowling ball is nearly a sphere, however the finger holes and sometimes a balance hole make a perfect sphere impossible.

dear dave,

is it time to go yet?

Dear Too young from Cincy,

Ok, you read the part about the earth is not round and then stopped reading - didn't you? It's the rotation that deforms the shape of the earth.

an interesting pespective of this deformity: An often-cited result of Earth's equatorial bulge is that the highest point on Earth, measured from the center outwards, is the peak of Mount Chimborazo in Ecuador, rather than Mount Everest. But since the ocean, like the Earth and the atmosphere, bulges, Chimborazo is not as high above sea level as Everest is.

Dear Patrick:

Now, but here is something to entertain you in the mean time.

Dear David:

Why does the earth rotate?

And who/what/how/where caused it to start moving?

Dear Eternally Annoying,

It is theorized that Earth formed as part of the birth of the Solar System: what eventually became the solar system initially existed as a large, rotating cloud of dust, rocks, and gas. It was composed of hydrogen and helium produced in the Big Bang, as well as heavier elements ejected by supernovas. As this interstellar dust is inhomogeneous, any asymmetry during gravitational accretion results in the angular momentum of the eventual planet.[sup][24][/sup] The current rotation period of the Earth is the result of this initial rotation and other factors, including tidal friction and the hypothetical impact of Theia.

Personally I don't think Theia had anything to do with it. My answer is somewhat simplistic, even though I doubt you would understand it - God made it that way!
