Which element is most commonly dissolved in seawater group of answer choices?

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.

When a lot of carbon dioxide is dissolved in seawater The seawater becomes?

Carbon dioxide is added to the atmosphere whenever people burn fossil fuels. Oceans play an important role in keeping the Earth’s carbon cycle in balance. As the amount of carbon dioxide in the atmosphere rises the oceans absorb a lot of it. In the ocean carbon dioxide reacts with seawater to form carbonic acid.

Which of the following is the longest topographic feature on Earth?

The mid-ocean ridge

The mid-ocean ridge is the longest topographic feature in the world spanning about 40 000 miles around the planet. The ridge is composed of volcanoes and is broken up by enormous fractures that create rift valleys.

What is the most abundant substance dissolved in sea water carbon dioxide sodium chloride magnesium chloride magnesium?

The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium calcium potassium and mercury amongst many other elements some in minute concentrations.

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. Near the equator the tropics receive the most rain on a consistent basis.

Is the ocean getting saltier Why or why not?

Rain replenishes freshwater in rivers and streams so they don’t taste salty. However the water in the ocean collects all of the salt and minerals from all of the rivers that flow into it. … In other words the ocean today probably has a balanced salt input and output (and so the ocean is no longer getting saltier).

What is the most abundant element in Earth’s atmosphere?

Nitrogen

The most abundant naturally occurring gas is Nitrogen (N2) which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%. The inert gas Argon (Ar) is the third most abundant gas at . 93%.

What happens when co2 dissolves in seawater?

When carbon dioxide dissolves in seawater most of it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH. In addition some of the hydrogen combines with carbonate to form more bicarbonate decreasing the concentration of carbonate in seawater.

How does co2 react with seawater?

Carbon dioxide reacts with seawater to form carbonic acid which releases hydrogen ions reducing pH. Since industrialization the pH of ocean surface waters has declined 0.1 units reflecting a 30 percent increase in acidity.

What are the two main factors that affect seawater density?

There are two main factors that make ocean water more or less dense: temperature and salinity. Cold salty water is denser than warm fresher water and will sink below the less dense layer. Density is defined as the measure of a material’s mass (e.g. grams) divided by its volume (e.g. milliliters).

What are the major gases dissolved in seawater?

Seawater has many different gases dissolved in it especially nitrogen oxygen and carbon dioxide. It exchanges these gases with the atmosphere to keep a balance between the ocean and the atmosphere. This exchange is helped by the mixing of the surface by wind and waves.
