It's basically a question of balance.
Let's say you put a sponge soaked in freshwater into sea water.
The sponge represents land, and the water in it is the ground water.
At the beginning, the water presssure inside the sponge is pretty much the same as the pressure outside the sponge, so there isn't really anything pushing the sea water in, because the fresh water is pushing back equally hard.
Now you put a straw into the sponge(drill a well), and start sucking the fresh water out.
Suddenly, there's less freshwater pushing the sea water back, and it will begin to seep in.
The sea is made of water therefore all water in it is below sea level. Ground level is the surface of the dry ground. Your question therfore makes no sense.
The transfer of water through the ground and back to the sea is called precipitation.
ground water seeping in the ocean or sea that can be done
ground water seeping in the ocean or sea that can be done
both.
Because it is not connected to the sea water. It is stored as under ground water
salt is formed in the sea by water from rivers and streams washing salt from the ground into the ocean.
Small lake, Oasis, and ground water bodies can be found as well as ground water from the Nile river. Salt water sources: Khalij Surt (Gulf), Golfe de Gabes (Gulf), and the Mediterranean Sea (Sea).
Water either flows back to the sea or (a little) sinks into the ground.
a sea is an ecosystem because it helps and provides for communities and populations. there is another world of animals that live in the sea. the sea is like above the ground but it is under water (:
When they say the airport is "located below sea level" (as is about 1/3 of the Netherlands) it means the land is dry, but the ground is actually lower down than sea level. Fortunately, it is seperated from the sea by higher ground.
It's polluted by the human race using it as a dumping ground for chemicals, refuse and human waste !
