With the earth surrounded by huge oceans....?

Question

Do you still believe that The earth is round???

welll, I wrote my question at 4am and I'm very tired.. I noticed that it was not formulated properly... What I meant was that continents are surrounded by oceans that are quite deep and sense the earth was mostly made of water..I was wondering about the real shape of the earth without the water

Basically, my question is what shape would the earth be if there was no water

Answer 1

Yep... it's called gravity - look it up sometime

Now that you've re-formulated your question perhaps I should re-formulate my answer...

The Earth would still be basically spherical without the oceans... except that the surface would appear more uneven than it does with the seas because the oceans cover up many of the "mountains" and "valleys". The highest mountain (from base to summit) would be Hawaii and the deepest valley would be the Marianas Trench but the variation from highest point to lowest would still be only a tiny proportion relative to the size of the Earth. Mars is a much smaller planet but has higher mountains and deeper valleys than anything on Earth.

Answer 2

The water gets very deep in some places, but the Earth's surface area is so big that even mounains like mount everest don't affect the it. Even tall peaks and low points of the ocean still aren't deep/tall enough to make the world not round.

It's like saying the black rims or the little bumps of a basketball make the overall surface area not round..

Answer 3

Earth's oceans filled in two ways. I'm assuming that you don't just mean "from rivers." In our early history, we were pummeled by comets, which are largely water ice. When they hit, they turned to water vapor. At the same time, there was an *enormous* amount of volcanism (volcanoes erupting) going on, and even though we don't normally think about this, volcanoes release lots and lots of water vapor (you see it as thick steam). Finally, our young crust was directly de-gassing -- letting out various gases, including water vapor. All of these sources came together to cause precipitation (rain) that over millions of years filled our ocean basins with water. Then, over millions of more years of wild geologic activity, mountains building and being eroded, the ions that made our ocean the proto-ocean of what we know today were actually washed into it in rivers and sometimes as direct laminar/sheet runoff (mostly by rivers). This is how the NaCl "sea salt" got in, as you clearly know. Well, sodium and chlorine ions are there just because they were in the most abundance to get there in the first place. Obviously, there are more, but in much lower amounts, given in parts per million: For reference --> Chloride (Cl) -- 19,345 Sodium (Na) -- 10,752 The rest --> Sulfate (SO4) -- 2,701 Magnesium (Mg) -- 1,295 Calcium (Ca) -- 416 Potassium (K) -- 390 Bicarbonate (HCO3) -- 145 Bromide (Br) -- 66 Borate (BO3) -- 27 Strontium (Sr) -- 13 Fluoride (F) -- 1 It was pretty hard to isolate that single fluoride per million parts. Be sure to note, however, that the ocean is not one perfectly homogeneous bowl of water. For instance, the Arctic Ocean is *much* lower than the Red Sea.

Answer 4

you are right? However water is part of earth, so you cannot exclude the presence of water for its shape. Sure other planet do not have water, but if there is no water, as time goes by the rotation of the planet will cause it to become round.like how u make a ball from plasticine.by rotatin it.

earth is not round, it's the shape of a "burger"

Answer 5

The deepest ocean gorge and the tallest mountian are about 20,000 meters different altitude.

The earth is 8,000,000 meters in diameter. If the earth were shrunk to the size of a billiard ball, the finish would be about as smooth as a standard billiard ball.

Answer 6

If Holden is telling the truth then that is fascinating. But if the earth were shrunk to the size of a billiard ball it wouldn't be as smooth as a billiard ball because a billiard ball would be smaller still. Unless you're proposing that the earth shrinks, but the billiard balls don't, in which case we'd be living in a solar system of billiard balls or "a snooker game" which is just hypothetical nonsense at the end of the day

Answer 7

With or without the water.
With or without the mountains,gorges,valleys,plains etc...earth is round!

It is just like the pyramids, seen from afar their perimeters look straight hence triangular but as you come closer you begin to see the crevices, some boulders jutting outward/inward and generally one loses the sense of their angular shape but they are still triangular.

Answer 8

LOL I hope you're not serious. The earth is surrounded by space, it's just mostly composed of water. Check out google earth!

Answer 9

Yes, it is kind of round because of the combination of gravity and rotation forces. Actually, it is not exactly a sphere, but a geoid, flat in the poles and wider in the equator.

Answer 10

Wow, surrounded by oceans...hey, i never knew that. No, the earth must be flat. As flat as the pancakes i'm thinking of making this morning. Thanks for the info.
