This huge earth is covered by appx.70% water. Where did it all come from? Could it all be due to condensation.

Question

...from the earth's cooling off, after it was formed, 4.6 Billion years ago?

Okay, so what caused the earth to have an envelope-shaped atmosphere (containing moisture), and rising up to about 60,000', before dispersing into space...

Answer 1

Water's main component is hydrogen--H2o. Hydrogen is prominent throughout the entire universe. Water collected on most planets as the cosmos evolved, but they lost their water, and also their oxygen as well because other the planets gravitational pull was not capable of holding and locking it to the surface. Our water has been here since the beginning, and it is said that there is not one drop more here now than when earth was created, and not one drop less.!Water (H2o)= The H stands for hydrogen which the universe is sopped in. o means oxygen. H2o then means: 1 part hydrogen and 2 parts oxygen, and when they are linked chemically together they change into water as we know it. We have so much water because the universe is filled with hydrogen and oxygen, all the stars you see at night--they all run on these two chemicals. It is everywhere!

Answer 2

No. Not if you mean condensation from an atmosphere, unless the atmosphere was way way way bigger than it is now. Simply isn't enough mass to account for the amount of water now present as liquid on the earth's surface.

Most of the water now on the surface came from outgassing of the interior of the earth. Clearly some water came from the collision of solar objects (just as some of the rock on earth came this way), but I find this particular theory as the primary source of water similarly untenable due to mass constraints.

I need to say that I am discussing impacts that occurred after the main accretionary stage of the planet formation (after the earth cooled to the point of forming a solid crust). Obviously all of the water originally in the earth came from collisions, those that occurred during the post-nebular planetary accretion process, as did all of the rock and iron, at least if this is in fact the way in which the earth was originally formed.

Answer 3

Scientists believe that while some water was originally on earth, more came from water vapor in the atmosphere, and from water in rocks that was released during the earth’s formation. Rainwater was released from clouds in the atmosphere (what we refer to as part of the water cycle). As the earth cooled, more water came up from volcanoes, hot springs, and other sources. Gradually our oceans were filled.



Finally the day came when the falling raindrops did not hiss away in steam, but stayed to start filling the crevices and corners of the naked planet. Then it rained, and the accumulation of the seas began. The accumulation did not take place (in the opinion of modern geologists) through "the greatest deluge of all time" that has so often been described. So far as anyone can tell, it may merely have rained as it rains today. Nature has plenty of time. It probably took a billion years to fill the oceans

Answer 4

As a non-Scientist I will take a guess. Mmmmmmm...where did water come from. I know plastic bottles in supermarkets??? Oh better still: taps in the kitchen???
Nah that can't be it - the early people on the planet didn't have supermarkets or proper bathrooms - lucky things probably used outdoor spas and hot springs and the odd few possibly went to Indian Wells???? Now it has just hit me - the correct answer has to be rain!! Surely that's it like when there was lots of violent stuff happening and the earth was in it's infancy being formed and oceans coming into being well you would think that it was rain that fell down to create the oceans like lots of nice violent thunderstorms and lightening and scary stuff so I will go with rain and then yes condensation rising to more rain and blah blah blah. Just had an interesting thought: Is there the same amount of water all over the planet today as there was say back when...???? or even back last week??? Like does any of it ever disappear. Like if there is rain and then condensation and so on and so forth is there any "wastage??????

Answer 5

Water is the second most common molecule in the universe. Hydrogen is the most common element so H2 is the most common molecule (95% of the universe). Helium is second, but it rarely bonds to anything (between four and five %). Oxyogen is the third most common element making H2O the second most common molecule. It came from a star (our Sun). Condensation has nothing to do with why it's here. There would've been many years of rain 4.6 billion years ago but that's from water that is already on our planet.

Answer 6

Well, you can't have condensation without water being present in the first place. However, yes, when the planet was forming and the general temps were above the boiling point, all water would exist in vapor form. Much like it is now on Venus.
Water is just the combining of hydrogen and oxygen, fundamental elements in the universe, and is present throughout space and on many worlds in some for mor another.

Answer 7

You can't have condensation without the water already being there.

Current theories suggest that much of the water came from comets that hit the planet and melted. Comets are mostly ice. Now, where did they get the water? That has not yet been explained on Discovery.

Answer 8

In the beginning of the world, there was one ocean. Man decided to give sections of it names. These names have stuck for thousands of years. Oh by the way just for your edification there is 71% of the world covered by salt water. Approximately 361 million sq. Kilometers. And of that over half is 3,000 meters deep.

Answer 9

science has proven a flood. Jesus was in the wilderness 40 days and 40 nights which is the number which represents testing. 7 is the number representing completion...hence forgiveness was meant to never cease making it complete.

Answer 10

Yes and from comet collisions. Comets are mostly ice. When a comet hits a hot planet, it melts.
