Why is ocean water salty?
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.
Ocean water seeps into cracks in the seafloor and is heated by magma from the Earth’s core..
What ocean is most dangerous?
The South China Sea and East Indies, eastern Mediterranean, Black Sea, North Sea, and British Isles are the most dangerous seas in the world, with the greatest number of shipping accidents in the last 15 years, according to a report released by the World Wildlife Fund (WWF).
Why is the ocean water Brown in South Carolina?
The large area of discolored water may be caused by sediment and tannins in area rivers draining into the ocean. Tannins are natural organic material produced by leaves & tree bark that leach into rivers. Tannins are harmless. In fact, it’s what gives the tea you drink its color.
Why is space black?
Around Earth and the inner solar system, for example, space is filled with dust particles that get lit up by the sun, creating a diffuse glow over the entire sky. But that dust isn’t a problem out where New Horizons is. Plus, out there, the sunlight is much weaker.
How dark is space?
While we all know that stars emit plenty of visible light, we’ve generally assumed that space, as a whole, is completely dark in the absence of stars. And it is definitely dark, but apparently, it’s not that dark.
Why is dirty water bad for you?
Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and polio. Contaminated drinking water is estimated to cause 485 000 diarrhoeal deaths each year.
How far is the blue sky from Earth?
It extends from Earth’s surface to an average height of about 12 km, although this altitude actually varies from about 9 km (30,000 ft) at the poles to 17 km (56,000 ft) at the equator, with some variation due to weather.
Is the ocean or the sky 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.
Does space ever end?
Interplanetary space extends to the heliopause, whereupon the solar wind gives way to the winds of the interstellar medium. Interstellar space then continues to the edges of the galaxy, where it fades into the intergalactic void.
What does space smell like?
As it turns out, space actually does have a distinct odor. … Astronauts returning from space claim that their suits smell, in a word, burnt. The lingering scent of space is “acrid” and “metallic,” reminding the astronauts of charred meat or welding fumes.
What makes the sky blue?
The Short Answer: Gases and particles in Earth’s atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Why is the ocean blue but water clear?
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. In water, absorption is strong in the red and weak in the blue, thus red light is absorbed quickly in the ocean leaving blue.
Why is Bahamas water so clear?
Oceans move east to west as the Earth spins because of its rotation, creating a phenomenon known as upwelling. … In the Bahamas, meanwhile, coral reefs act as a barrier to break the force of upwellings. There are areas in the Pacific that still have clear water and heavy waves, but that’s because of what’s in the water.
Is blood actually blue?
Your blood is actually red. The blue hue of your veins has more to do with how your eyes absorb and see color than the color of the blood itself. The level of oxygen in your blood cells determines the brightness of the red color. Blood pumped directly from the heart is oxygen rich and bright red.
Why are waves white?
Water is colourless and transparent, but why does the foam on breaking waves appear white? … Foam consists of bubbles, which are very thin liquid films with air inside. Compared with a water droplet of the same size, a bubble absorbs much less light than the water droplet because it has so little matter.
Why is sky and ocean blue?
The sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength. … The ocean is not blue because it reflects the sky, though I believed that up until a few years ago.
What color would the sky be if there was no ocean?
blueWhat color would the sky be if the Earth wasn’t mostly covered with water? I know the sky is blue because the light from the sun reflects off of the oceans, but what if there were no oceans? The sky is blue because of Rayleigh scattering, not because it’s reflecting the blue colour of oceans.
Is water really 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.
