Is there water anywhere other than Earth
Earth isn't the only ocean world in our solar system. Water on other worlds exists in diverse forms on moons, dwarf planets, and even comets. Ice, water vapor in the atmosphere, and oceans on other worlds offer clues in the quest to discover life beyond our home planet.
Is the Earth still 70% water
But just how much water exists on, in, and above our planet About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water.

Water does not leave Earth, nor does it come from space. The amount of water the world has is the same amount of water we've always had. However, we could run out of usable water, or at least see a drop to very low reserves.

Was the Earth 100% water
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.
When was Earth 100% water
It suggests that most of Earth's water was on the surface at that time, during the Archean Eon between 2.5 and 4 billion years ago, with much less in the mantle. The planet's surface may have been virtually completely covered by water, with no land masses at all.
Are humans 30% water
Most of the human body is water, with an average of roughly 60%. The amount of water in the body changes slightly with age, sex, and hydration levels. While the average percentage of water in a person's body is around 60%, the percentage can vary from roughly 45–75%.
Are humans 80% water

Is the Earth 95% water
About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog. Water is never sitting still.
Is the Earth 98% water
Earth is known as the "Blue Planet" because 71 percent of the Earth's surface is covered with water. Water also exists below land surface and as water vapor in the air. Water is a finite source.

Is the human body 95% water
The entire human body is about 66 percent water. Our bones are composed of 22 percent water, muscles are 76 percent and blood is 83 percent. Lungs are 90 percent, and our brains are actually 95 percent water. It is easy to see why water and hydration play such a critical role in a healthful lifestyle.
Is the Earth 99% water
70% of the earth is covered in water, yet only 3% of it is fresh. Of that 3%, 2.6 of it is locked away in glaciers and polar ice caps. That leaves us with 0.4% of the earth's water, in the form of rivers and underground aquifers, to try to utilize for our consumption and societal development.
