Water on Earth is believed to have been brought here by comets and asteroids during the early formation of the solar system. These icy bodies contained water that melted and became the vast oceans and lakes we have today. Additionally, water vapor released from volcanic activity also contributed to the presence of water on Earth.
What else can I help you with?
Does the earth still produce water or do you still have the same amount that was there when the earth was born?
Earth does not produce water. The water currently on Earth is believed to have been here since shortly after Earth formed. Water on Earth goes through cycles between the atmosphere, the oceans, and glaciers.. Some water vapor is released by volcanoes, but this is balanced by water carried into the mantle at subduction zones.
How did water came on this earth?
There are various theories as to where all the Earth's water came from, but several theories have fared better than the others. We know that the oceans existed as early as 100 million years after the formation of the Earth. When the Earth was in the process of forming, with a radius just 40% smaller than at present, it would have had enough gravity to hold on to a tenuous atmosphere with watervapor. The first water vapor on the planet would have come from the planet's internals, where volatile (low weight) chemicals would have a tendency to float to the top, and heavy chemicals (iron and nickel) would sink. Though the first of Earth's water came about through volcanism, this alone probably didn't produce enough to form stable pools on the surface. More water was added to the planet during several hypothesized large impacts from asteroids from the outer asteroid belt. Comparing the isotope ratios of water on Earth and water from comets and asteroids has revealed that the majority of the Earth'swater comes from asteroids.
What percentage of earth water is found in lakes?
don't believe that it is less than 3% as said on another answer, my answer is a professional one that came from explorelearning.com on the water cycle gizmo, the answer is 0.009%.
Water on earth or earth in water?
It is more correct to say that water is on the earth. Though the surface of the earth is mostly covererd with water, the operative word is "covered." The water covers most of the earth's surface, so the water could be said to be sitting on the earth. Which it is.
What condition had to be in place on earth for water to exist here?
For water to exist on Earth, the temperature needed to be within a range where it could exist in liquid form, between 0-100 degrees Celsius. Additionally, Earth's atmosphere needed to have the right combination of gases, like oxygen and nitrogen, to create the conditions necessary for water to form and remain liquid.
How you came here to earth?
From my mum?
How do scientist think plant life came to earth?
They do not think plant life 'came' to Earth. They believe it evolved here.
Will the water supply last forever?
yes...the water is in constant cycle, and there is as much water as there ever has been (except for the first ages of the earth, before the water came to be here) and as there ever will be (until the earth is vapourised). Will there be enough to satisfy the increasing population is another question entirely.
What forms of water on Saturn?
The form of water on saturn is the form of water we have here on earth.
How is water prudused?
Water is not produced. It is believed that all of the water on earth came from comets and other blocks of ice landing on earth from the solar system.
Scientists think the first water vapor on Earth came from?
From the oceans
Where did the waters of the earth came from?
A mist used to rise from the surface of the earth and water the whole surface of the earth. Hope this helped!! :)
Where water came from?
I comes from everywhere, because the water cycle enables water to move everywhere by the processes of evaporation, precipitation, sublimation, condensation and flow. Originally almost all the water on earth came from comets, and comets still contribute water to the earth every day.
Where does water came from?

Where do water come from?
they come from clouds through precipitation but some people think that water came on earth when the meteors hit earth at the beginning of time and released water
Will water stay on earth forever?
If the rain still falls then yes we have a good chance of water staying here on earth forever:D
