How old is the first ocean?

Are there shadows underwater?
Deep in The Ocean, There’s a ‘Shadow Zone’ Where The Water Is 2,000 Years Old The reason, according to a new analysis of deep water movements called abyssal overturning circulation, is due to the geometry of the seafloor, which for long periods prevents very deep, dense ocean waters from circulating to the surface
How old is the water we drink?
The water you drink may be composed of the same water molecules that have been around since life started on this earth 46 billion years ago

Why is the ocean blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water
Could there be dinosaurs in the ocean?

Who named Indian Ocean?
The Indian Ocean has been known by its present name since at least 1515 when the Latin form Oceanus Orientalis Indicus (“Indian Eastern Ocean”) is attested, named for India, which projects into it
How old is deep ocean water?
Which of these scenarios is responsible for the majority of water in the oceans is still unclear, but we know that most of the water in the oceans (and on the rest of the planet) is very ancient – on the order of 4 billion years old
Are there still waters in the ocean?
If you have ever been seasick (we hope not), then you know how the ocean is never still You might think that the water in the oceans moves around because of waves, which are driven by winds But, actually, there are currents and “rivers” in the oceans that move massive amounts of water around the world
What is Pacific shadow zone?
Deep within the eastern North Pacific Ocean lies the “shadow zone,” a massive reservoir of nearly stagnant seawater trapped between the ocean floor and shallower currents
Do we drink dinosaur pee?
As for the dinosaur pee- yes it’s true we are all drinking it As dinosaurs roamed the earth longer than humans (186 million years during the Mesozoic era), it is theorized that 4 cups out of the 8 recommended cups of water a day have been at one point in time dinosaur pee
Does water expire?
Water is a natural substance and does not go bad, however the plastic water bottle will degrade over time and begin to leach chemicals into the water, which is why it is always important to choose BPA free bottled water
Is water older than the sun?
Around 70 percent of the Earth’s surface is comprised of water, and our big, blue, planet is filled with rivers, streams, and oceans that defy everything scientists have come to learn about the formation of Earth

What Colour is water?
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 The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue
Why is the ocean salty?
Ocean salt primarily comes from rocks on land and openings in the seafloor Rocks on land are the major source of salts dissolved in seawater Rainwater that falls on land is slightly acidic, so it erodes rocks This releases ions that are carried away to streams and rivers that eventually feed into the ocean
Why is the ocean so scary?
It’s pretty justifiable to find the ocean scary because of rip currents, sharks, or the possibility of drowning Whether you realize that you’re actually afraid of open water because you aren’t a strong swimmer — or sharks because, well, they’re sharks — you can start to combat your anxieties with information
