Oceanography
Oceanography, also called marine science, is the study of oceans. It includes the study of physical oceanography, marine chemistry, marine geology, and marine biology. Areas covered in oceanography are the shape, depth, and distribution of oceans, and also their composition, life forms, ecology, and water currents, as well as their legal status. If you would like to know more or share your knowledge about oceanography, ask and answer questions here! Includes questions related to the study of Earth's oceans and seas.

From the spectrum of the visible light water absorb red, orange, yellow and green radiations. And the result is that we see the blue and violet radiations. Red, orange, yellow and green radiations have longer wavelengths than blue, indigo and violet radiations. The depth of water and variation of composition play also a role.

Where did salt in the ocean come from?
Salt in the ocean comes from the land. The elements that make up salts, such as chlorine and sodium, started out in rocks. Water and acids eroded the rocks, and rivers carried the elements into the sea. The oceans usually contain 35 parts of salts for every 1000 parts of sea water. This is lower in some places where there is a lot of fresh water coming into the ocean. It is higher where the Sun is very strong and evaporates more of the water. When all the water is gone, the salts are left behind as solid, white crystals.
The right amount of salt is a very important part of our diet. In ancient times, salt was worth its weight in gold. People used it to flavor and preserve their food. Without salt, the food would spoil. For this reason, salt became a symbol of purity. Some sacrifices in the Old Testament included salt (Leviticus 2:13; Ezekiel 43:24). Jesus called faithful people "the salt of the earth," and the apostle Paul said that our speech should be "seasoned with salt" (Colossians 4:6).
