How do chemical elements get into the ocean?

Answer 1

Water, as it washes over rock and through the soil, picks up minerals including salts and other minerals. The water flows downhill until it reaches the oceans.

The water only has a little bit of the dissolved mineral, but after it mixes with the ocean the water evaporates leaving the minerals behind. Slowly, over the history of the earth, minerals in the oceans have become more concentrate until they get to the concentration that they have now.

As to where the water that now fills the sea come from in the first place, there are two probable sources for the majority of the water:

• The first is that water (as ice) was in the rubble that collected in the early solar system that eventually Accumulated to form the Earth. Studies indicate that water was present on Earth almost from its beginning son 4.4 Gyr ago.
• The second is that the original water was supplemented by icy comets crashing into the earth soon after its formation.

Answer 2

From sodium chloride (NaCl). In water NaCl will dissociate into Na+ and Cl-. There are also other ions in seawater, such as potassium and calcium but at much low concentrations the Na+ and Cl.

Answer 3

The salt in seawater gets there when rivers are flowing by rocks in the riverbed or seabed, and the salt in them gets washed into the seawater.

Answer 4

Through volcanic eruptions, large quantities of water vapor and other gases.

Answer 5

Volcanic erruptions
