Can water be alive?
Water is non living.
We talk about alive or dead only when it comes to living organisms.
Living organisms are made of one or more cells and these cells are responsible for their living nature.
It isn’t made of cells..
Where is water found?
The ocean holds about 97 percent of the Earth’s water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes. Of the world’s total water supply of about 332 million cubic miles of water, about 97 percent is found in the ocean.
Who found h2o?
It was the chemist Henry Cavendish (1731 – 1810), who discovered the composition of water, when he experimented with hydrogen and oxygen and mixed these elements together to create an explosion (oxyhydrogen effect). In 1811 the Italian physician Amedeo Avogadro finally found the H2O formula for water.
How do we know water is h2o?
H2O is the chemical formula of water. It means that each molecule of water is made up of two hydrogen atoms, indicated by the letter H, and a single oxygen atom, represented by the letter O. Water is chemical substance with no smell, taste or color.
Why is water wet?
“Water is wet because when something is wet, it has water on it and on a molecular level, water molecules are bonded on top of each other, therefore water is wet.” An extension to the previous argument that a couple of students brought up was that one water molecule alone is not wet, but when water molecules touch each …
Is water actually blue?
The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. … Rather, water blueness comes from the water molecules absorbing the red end of the spectrum of visible light.
What created earth?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.
When was the water discovered?
3.8 billion years agoA sample of pillow basalt (a type of rock formed during an underwater eruption) was recovered from the Isua Greenstone Belt and provides evidence that water existed on Earth 3.8 billion years ago.
Where can h2o be found?
The water on the surface of Earth is found mainly in its oceans (97.25 percent) and polar ice caps and glaciers (2.05 percent), with the balance in freshwater lakes, rivers, and groundwater.

How did water get its name?
The word water comes from Old English wæter, from Proto-Germanic *watar (source also of Old Saxon watar, Old Frisian wetir, Dutch water, Old High German wazzar, German Wasser, vatn, Gothic 𐍅𐌰𐍄𐍉 (wato), from Proto-Indo-European *wod-or, suffixed form of root *wed- (“water”; “wet”).
Can ice be wet?
Ice on its own is not wet, because it’s a solid. However if the ice is in an environment that’s warmer than 0°C, the surface of the ice will be wet, because it is melting. If it’s cold enough to not melt on contact, then no, ice is not wet. It’s a solid, not liquid.
How the water is formed?
Much of Earth’s water is thought to have come from asteroids impacting the planet early in its history. Image via NASA/Don Davis. The surface of the very young Earth was initially an ocean of magma. Hydrogen and noble gases from the solar nebula were drawn to the planetary embryo, forming the first atmosphere.
How old is the water we drink?
The water on our Earth today is the same water that’s been here for nearly 5 billion years. Only a tiny bit of it has escaped out into space.
