Technically, neither. They are both the same weight but not exactly weigh anything as water can alter our weight.
sea water
The land mass is heavier even tough the sea covers 2/3 of the earth's surface it still has land under the sea hence it is heavier... == == == == Land mass will be heavier than water because it is more dense
It depends! On what you say? Well, as an example it depends on the temperature of the sea water. The colder the water the greater the amount of DO can be contained. It depends on where the sea water is located; e.g., sea water at the mouth of the Amazon River (or at the mouth of most any river emptying into the oceans) for the fresh water from the river dilutes the salt content of the sea water there.
About 97.5% of water on Earth is salt water and 2.5% fresh water.Of the 2.5% fresh water, 1.75% is frozen, but we're working on that.97% salt water in the earths sea only 2.5% is fresh water in the seas
The sea is salt water which has a lower freezing point than fresh water in the snow. Additionally the sea is continually moving (waves) which will need a lower temperature to cause freezing
no vinegar is heavier
If you have equal volumes, the salt water will weigh more.
Salt water is heavier
because the salt water ie heavier than fresh water
Sea water and fresh water does not have the same density because sea water has salt, which makes it more dense than fresh water Sea water and fresh water does not have the same density because sea water has salt, which makes it more dense than fresh water
Fresh water - sea water kills.
Sea water is salt water.
Put it in the sea.
Fresh water...
Fresh water animals.
Salt water is denser than fresh water.
33 feet in sea water, 34 feet in fresh water
The bering sea is salt water.
