What are the 2 sources of dissolved substances in ocean water?

What are the 2 sources of dissolved substances in ocean water?

The two ions that are present most often in seawater 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.

What are the two most abundant elements dissolved in seawater what is produced when these elements combine quizlet?

The two most abundant elements dissolved in seawater are chlorine and sodium, which combine to form sodium chloride.

What are the two factors that influence seawater density which one has the greater influence on surface seawater density?

The density of seawater depends on temperature and salinity. Higher temperatures decrease the density of seawater, while higher salinity increases the density of seawater. The following figure shows how density is affected by temperature and salinity. The lines through the figure are lines of constant density.

What are a source of dissolved substances in the ocean?

primary sources of dissolved substance in the ocean. chemical weathering of rocks on the continents is one source of elements found in sea water. what is most salt in sea water? Seawater contains dissolved substances that give it a salty taste.

What is composition of ocean water?

Seawater, water that makes up the oceans and seas, covering more than 70 percent of Earth’s surface. Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases.

What are the six most abundant components dissolved in seawater?

Chemical and physical properties of seawater The six most abundant ions of seawater are chloride (Cl−), sodium (Na+), sulfate (SO24−), magnesium (Mg2+), calcium (Ca2+), and potassium (K+). By weight these ions make up about 99 percent of all sea salts.

What are the three main layers of the ocean?

The ocean has three primary layers. 2. The layers are the surface layer (sometimes referred to as the mixed layer), the thermocline and the deep ocean. 3.

What three factors can change the density of water?

Water density changes with temperature and salinity. Density is measured as mass (g) per unit of volume (cm³). Water is densest at 3.98°C and is least dense at 0°C (freezing point).

What factors influence water density and which is most important?

Answer: There are two main factors which affect the density of water, namely, Temperature and Purity. The density of pure water varies with temperature and attains its maximum value at a temperature of 4^{0}C. Impure water density increases with respect to impurity.

What is the highest salinity?

The highest salinity is recorded in the western Baltic, where it is about 10 parts per thousand at the surface and about 15 parts per thousand near the bottom; the lowest is at the head of the Gulf of Bothnia, where…

Which ocean is the saltiest?

the Atlantic Ocean
Of the five ocean basins, the Atlantic Ocean is the saltiest. On average, there is a distinct decrease of salinity near the equator and at both poles, although for different reasons.

Where do the dissolved components in seawater come from?

The two primary sources for the materials that comprise the dissolved components in seawater are chemical weathering of rocks on the continents and meteorites hitting the ocean.

Where does sodium chloride in seawater come from?

Sodium chloride, or common table salt, is produced when the two most abundant elements combine. What are the two primary sources for the elements that comprise the dissolved components in seawater? Chemical weathering of continental rocks and volcanic eruptions putting elements from Earth’s interior into the seawater.

What causes the salinity of the ocean to vary?

Chemical weathering and from the Earth’s interior (volcanic eruptions). List several factors that cause salinity to vary from place to place and from time to time.

Which is the most abundant element in the ocean?

The average salinity of the ocean is 35 parts per thousand. What are the six most abundant elements dissolved in seawater? What is produced when the two most abundant elements combine? The six most abundant elements are sodium, chlorine, sulfur, magnesium, calcium, and potassium.
