Is the ocean getting saltier over time?
Yes, the ocean is getting saltier over time due to factors such as evaporation and human activities like mining and agriculture that contribute to increased salt levels in the water.
Why is the Mediterranean Sea so salty?
The Mediterranean Sea is salty because it has a high rate of evaporation and low freshwater input from rivers. This causes the water to become more concentrated with salt over time, making it saltier than other seas and oceans.
How do sediments lay when they deposit in lakes or oceans?
When sediments deposit in lakes or oceans, they typically settle in layers on the bottom of the body of water. Over time, these layers can build up and form sedimentary rock.
According to scientific hypothesis how oceans formed?
One hypothesis suggests that the Earth's oceans formed from water-rich asteroids and comets colliding with the planet during its early history. This water then accumulated over time to create the oceans we see today. Another hypothesis suggests that water vapor released from volcanic activity contributed to the formation of the oceans.
How have the oceans changed over time?
In the last Ice Age, the oceans would have been several hundred metres lower than they are. And in a ice-free period the ocean level would be several tens of metres higher - perhaps 50m or so
Do the oceans get saltier over time?
no they don't
Is the ocean getting saltier over time?
Yes, the ocean is getting saltier over time due to factors such as evaporation and human activities like mining and agriculture that contribute to increased salt levels in the water.
Why aren't the oceans getting saltier?
My off-hand guess would be that they are getting less salty on average as fresh melt-water from Greenland and the polar caps enters the oceans.
What happens to ocean water that does not evaporate?
The water that doesn't evaporate into vapor stays in the ocean as liquid water. The oceans have a lot of liquid water. Over time, ocean water is always evaporating and turning into rain and comes back to the ocean; but the salts and minerals carried into the sea from rivers never evaporate. They stay dissolved in the ocean waters and make it saltier and saltier.
Why is the Mediterranean Sea so salty?
The Mediterranean Sea is salty because it has a high rate of evaporation and low freshwater input from rivers. This causes the water to become more concentrated with salt over time, making it saltier than other seas and oceans.
Why is the rivers not salty?
Rivers are not pure freshwater sources of water. As they flow to the ocean, they pick up small amounts of mineral salts. These slightly-salty rivers flow into the ocean, and as this is a continuous flow and there are thousands of rivers, all the salt builds up, causing the oceans to be saturated with salt. Also, because water evaporates and salt does not, the oceans get saltier over time.
Does fresh water has more or less dissolved salts than seawater?
Salt or sodium chloride one is a metal poisonous and the other is gas poisonous to humans but combined is beneficial t humans. A very long time ago the seas were not salty . Salt comes from the earth as a solvent element when rains washes it eventually to the seas as consequence the seas are getting saltier and saltier .
How does the sea make salt naturally?
Salt and other minerals come into the sea from rivers. Some of the water evaporates from the ocean (leaving the salt) and more flows in. So the sea gets saltier over time.
Do oceans gain salt over time?
Yes. As silt is washed into the ocean, the salts in the silt are dissolved into ocean water.
How do sediments lay when they deposit in lakes or oceans?
When sediments deposit in lakes or oceans, they typically settle in layers on the bottom of the body of water. Over time, these layers can build up and form sedimentary rock.
Are the continents and oceans always been in the same positions they are today?
No, the positions of continents and oceans on Earth's surface have changed over millions of years due to the process of plate tectonics. Continents have drifted apart and collided to form new landmasses, changing the configuration of oceans. This movement is ongoing, with the positions continuing to shift gradually over time.
Where does the humpback whale live?
Humpback Whales live in all oceans over the world but do migrate and spend time in one place
