What if there was no water on Earth?

With no water supply, all vegetation would soon die out and the world would resemble a brownish dot, rather than a green and blue one. Clouds would cease to formulate and precipitation would stop as a necessary consequence, meaning that the weather would be dictated almost entirely by wind patterns.

What if the Earth was only water?

Answer 1: 71\% of the world is already covered with water. If the rest of the Earth were covered with water, then the entire planet surface would become one massive saltwater ocean and virtually every species that lives on land or in freshwater(e.g., streams, rivers, and lakes) would go extinct (die).

When did Earth have no water?

This presents somewhat of a paradox, as the cool early Earth hypothesis suggests temperatures were cold enough to freeze water between about 4.4 billion and 4.0 billion years ago. Other studies of zircons found in Australian Hadean rock point to the existence of plate tectonics as early as 4 billion years ago.

Is Waterworld possible?

The Answer: Not a damn bit. The premise of Waterworld is quite simple: Years of global warming has heated the atmosphere of Earth to the point that all ice deposits have melted. The ice already floating in the sea could melt in its entirety, and it wouldn’t change sea levels at all.

Did ancient Earth have no land?

If confirmed, the new research could help scientists pin down the origins of life. Although about 70 percent of Earth’s surface is currently covered in water, new research suggests ancient Earth might not have had any land at all. New research suggests ancient Earth was a water world, with little to no land in sight.

Was Earth once a water world?

New research suggests ancient Earth was a water world, with little to no land in sight. And that could have major implications for the origin and evolution of life. While modern Earth’s surface is about 70 percent water-covered, the new research indicates that our planet was a true ocean world some 3 billion years ago.

Is it possible for the Earth to be completely covered by ice?

Very definitely yes, if you’re prepared to accept water as the substance H2O. Because there have been times when the planet has been entirely covered by ice, that’s both the land masses and the oceans covered by ice from pole to equator.

Is it possible for the earth’s surface to be covered in water?

These are called the ice house world conditions, the most recent of which was about 635 million years ago so just before large amounts of multi-cellular life. Extreme climate events covering the Earth in solid water – yes. The questioner was probably thinking about liquid water.
