BRAINLIEST

Use the following data profiles to best describe the effect on density as temperature decreases and depth increases.

As depth increases and temperature decreases, density remains constant.
As depth increases and temperature decreases, density increases.
As depth increases and temperature decreases, density decreases.
As depth increases and temperature decreases, density does not follow a trend.


pleasseeee help will give brainliest

Answer 1

The density increases.

Explanation:
As you go deeper in depth, pressure increases. Density = mass/volume. The layers beneath us due to pressure get packed to the point of being very dense.

Answer 2

Answer:

Option (2)

Explanation:

In ocean water body, the upper surface of the water body is heated up due to the absorption of heat energy, as a result of which the temperature of the upper surface of the water body increases. With the increase in depth, the temperature gradually decreases, due to the lesser penetration of sunlight into the deeper water. So, the temperature and depth are inversely proportional to each other.

With the increase in the depth, and decrease in the temperature, it results in the increase in density. It is because the warmer water are less denser than the cold water, and this cold water are present at the bottom of the ocean. This cold water is comparatively rich in the salt content that increases its density.

So, it can be concluded that, as the depth of the ocean water body increases and the temperature decreases, the density increases.

Thus, the correct answer is option (2).
