They would sink to the ocean floor, but their bodies wouldn't decompose, because all marine bacteria would be dead too. Marine algae are responsible for at least half of Earth's oxygen production, so there would be mass extinctions on land as well.
Why does the ocean need salt?
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.
What would happen if we didn’t have salt?
The human body can't live without some sodium. It's needed to transmit nerve impulses, contract and relax muscle fibers (including those in the heart and blood vessels), and maintain a proper fluid balance.
Why is sea water 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.
Which ocean is not salt water?
The ice in the Arctic and Antarctica is salt free. You may want to point out the 4 major oceans including the Atlantic, Pacific, Indian, and Arctic. Remember that the limits of the oceans are arbitrary, as there is only one global ocean. Students may ask what are the smaller salty water areas called.
Is the ocean losing salt?
Since the late 1960s, much of the North Atlantic Ocean has become less salty, in part due to increases in fresh water runoff induced by global warming, scientists say.
Will the ocean ever run out of salt?
Ordinary sea salt is 97% sodium chloride whereas Dead Sea salt is a mixture of chloride, as well as bromide salts. Ordinary sodium chloride only makes up about 30%. That's still enough to supply the entire population of the UK with cooking salt for 70,000 years! So no, we won't be running out of salt any time soon!
Why is the sun yellow?
So, why does it generally look yellow? This is because the Earth's atmosphere scatters blue light more efficiently than red light. This slight deficit in blue light means the eye perceives the colour of the Sun as yellow. The more atmosphere the Sun's light passes through, the more blue light is scattered.
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.
