The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue. Rather, water blueness comes from the water molecules absorbing the red end of the spectrum of visible light.
Why is water blue but clear?
The reason the ocean is blue is due to the absorption and scattering of light. The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water.
Why is swimming pool water blue?
Looking at the structure of water itself, science tells us about the way the water molecules work. When interacting with light, the molecules actually absorb red light waves, whilst reflecting blue light waves. This selective process is known as electromagnetic absorption and is the main reason that water appears blue.
Why is water wet?
Water is wet, in the sense of being a liquid which flows easily, because its viscosity is low, which is because its molecules are rather loosely joined together.
Why is the ocean salty?
Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the 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.
Why is the ocean green?
What color is YOUR ocean? When the water looks especially green, it means there are a lot of microscopic algae (called phytoplankton) growing near the surface. Phytoplankton get energy from sunlight, just like plants do. Phytoplankton blooms commonly occur in the spring, when the days being to lengthen.
Why does the sea never freeze?
The gravitational pull of the moon, earth’s spinning motion, and thermal convection combine to create large-scale flows of ocean water known as ocean currents. This constant motion of the ocean water helps keep the water molecules from freezing into the somewhat stationary state of ice crystals.
Is there water in lava?
Lava does contain a lot of water, especially prior to eruption (when it’s called magma), but also as it flows across the ground,’ he explained. ‘As mentioned, though, water boils off immediately at those temperatures so it’s not liquid or even vapor water within the lava.
Is fire burnt?
Can fire *be* burned? Though as a wall built partly of flammable material I wish fire could be burned, it can’t. Fire is just the light and heat resulting from oxidation of fuel; there is nothing in fire to oxidize, because fire itself isn’t a substance it’s a process.
Is fire dry or wet?
“Fire is hot because thermal energy (heat) is released when chemical bonds are broken and formed during a combustion reaction. Combustion turns fuel and oxygen into carbon dioxide and water. … Both light and heat are released as energy.” So water is not wet and fire is hot.
Can you drink sea water if boiled?
Boiling seawater does not make it safe to drink because it does not remove the salt. On Average, seawater holds 3.5% salt, too much for the body to process. As seawater boils, it evaporates, leaving the salt behind. You’re making the seawater saltier by boiling it.
Is there Whale Sperm in the ocean?
Sperm whales live all over the world, meaning deposits of ambergris could be found floating on any ocean or washed up on most shorelines. But it is uncommon, found in less than 5% of whale carcasses.
