the figure shows the great ocean conveyor belt. which best describes what this model represents?

A. The model shows how ocean currents change the salinity of water.

B. the model shows how ocean currents move heat energy around earth

C. the model shows how salinity of water affects its density

D. the model shows how the density of water differs between the north Atlantic and other parts of the ocean.

Answers

Answer:

d

Explanation:

The ocean conveyor belt shows the movement of the oceanic water and the salinity. The model represents the density of the water in different regions of the world. Thus, option d is correct.

What are ocean conveyor belts?

Ocean conveyor belts are the oceanic current movement in their oceans across others and how the water moves across the water bodies across the globe.

The model shows that high salinity water gets heavy and sinks in the ocean of North Atlantic but the water of the Indian and the pacific oceans are less saline and remains at the surface.

Therefore, option D. the water differs in oceans based on density.

What causes water pollution?

Answers

Answer:

Good answer below, just adding on

Explanation:

Runoff of chemical products, animal waste, and especially human waste products such as different types of trash like scrap metals and plastic greatly increase water pollution.

when salt dissolves into water does it change its state

Answers

Answer:

no it doesn't change back

fine here When you dissolve salt in water, the sodium chloride dissociates in Na + ions and Cl - ions, which may be written as a chemical equation : NaCl (s) → Na + (aq) + Cl - (aq) Therefore, dissolving salt in water is a chemical change. The reactant (sodium chloride, or NaCl) is different from the products (sodium cation and chlorine anion).
