why ocean salty or how ocean become salty?

Question

why some countries have plenty of mineral raw oil deposit while others have few only or other countries do not have?

Answer 1

They are salty because that is the way GOD made them.

Answer 2

There are several theories about the origin of the seas, but no single theory explains all aspects of this puzzle. If you get into folk stories and mythology you will see that almost every culture has a story explaining how the oceans became salty. The answer is really very simple. Salt in the ocean comes from rocks on land. Here's how it works:

The rain that falls on the land contains some dissolved carbon dioxide from the surrounding air. This causes the rainwater to be slightly acidic due to carbonic acid (which forms from carbon dioxide and water). The rain erodes the rock and the acid breaks down the rocks and carries it along in a dissolved state as ions. The ions in the runoff are carried to the streams and rivers to the ocean. Many of the dissolved ions are used by organisms in the ocean and are removed from the water. Others are not used up and are left for long periods of time where their concentrations increase over time.

The two ions that are present most often in seawater are are chloride and sodium. These two make up over 90% of all dissolved ions in seawater. By the way, the concentration of salt in seawater (salinity) is about 35 parts per thousand. In other words, about 35 of 1,000 (3.5%) of the weight of seawater comes from the dissolved salts; in a cubic mile of seawater the weight of the salt, as sodium chloride, would be about 120 million tons. And, just so you don't think seawater is worthless, a cubic mile of it also can contain up to 25 tons of gold and up to 45 tons of silver! Before you go out and try alchemy on seawater, though, just think about how big a cubic mile is.

By some estimates, if the salt in the ocean could be removed and spread evenly over the Earth’s land surface it would form a layer more than 500 feet (166 m) thick, about the height of a 40-story office building.

why some country have plenty of raw oil deposit whlie others only few?
Petroleum is the name for all hydrocarbon related, naturally occurring materials, including oil, natural gas, and tar. It is made up of hydrocarbon molecules (hydrogen combined with carbon). Petroleum supplies almost half of our total energy requirements.

Countries that have plenty of mineral raw oil deposit already have this deposits thousands or million years ago, and the location of these countries are ideal for accumulation of organic material capable of forming petroleum and can occur in a number of different ways. Ideal environments are those which accumulate abundant organic material in non-oxidizing conditions. This can occur near the edge of larger sedimentary basins, behind barrier reefs, or in lagoon areas, where water circulation is more restricted. This is possible in smaller water body seas that may be connected to a larger ocean, or it may be isolated. If it is isolated, there is less circulation, and hence less oxygen. This situation is good for forming oil, because less of the organic material gets oxidized. The type of organic material which is deposited determines the outcome of the petroleum. Land derived organic material tends to produce more natural gas than kerogen. Marine derived organic material tends to produce more kerogen than natural gas.

Answer 4

Rain water falling on the land has a part in the weathering (breakdown) of rocks and the erosion (transport) of weathered rock fragments.

Rivers carry:
Larger rock fragments as bed load (rolling along the bottom of the stream),
Smaller rock fragments and mineral grains as suspended load (within the water column),
Ions or dissolved "salts" from the chemical weathering of rocks and minerals as dissolved load.
Feldspars are the most abundant minerals in the Earth's crust. Through a type of chemical weathering called hydrolysis, feldspars are altered to form clays, and their ions (Ca, K, and Na) are released to be carried in solution by running water, eventually making their way to the sea.

The weathering of other minerals and rocks also provides salts to the sea. For example, the calcite in limestone dissolves in slightly acidic natural waters, yielding Ca and CO3.

Rivers carry an estimated 4 billion tons of dissolved "salts" to the seas each year.

Some of these dissolved solids will be deposited as sediment, so yearly gains may roughly balance sediment deposition.

Salts have become concentrated in the sea (compared with freshwater) because the sun's heat causes the evaporation of water, leaving the salts behind.

Answer 5

Oceans are depositories. In other words they have no outlets only inlets. The minerals from fresh water sources have no way of getting back out so they continue to accumulate. This makes the oceans salty. Same with the Great Salt Lake here in Utah. Rivers only go into it, not out of it. I am sure there is a much more in depth detailed explanation than this but you get the idea.

Answer 6

The ocean gets it's salt from rivers & streams, which carry salt out into the ocean. The water from the ocean then evaporates, but in the process of evaporation, particulate matter is left behind (including salt). Over millions (possibly billions) of years, the salt has added up to be quite a bit.

Answer 7

yes, indeed, the ocean contains salt. But I know a myth of how oceans became salty... only i can't tell you

Answer 8

Ocean water is basic in nature, and rain water is acidic(acid rain) so, acid+base gives salt and water simple.

Answer 9

i think i heard that fast food chains have been dumping their old salty oil in the harbors around the world since the dark ages that is what killed the dinosaurs to much salt.
