A
An increase in ocean surface temperature causes <u>the density of ocean water might change.</u>
Explanation:
The density of the ocean's waters is dependent on temperatures. The lower the temperature the higher the density and vice versa. Therefore, when the ocean surface becomes warmer due to global warming so will the density of the waters becomes lighter. Warmer ocean waters mean the ocean level rise because the polar ice caps melt. The severity of storms also increases as the oceans feed more energy to storms.

<h2>Right answer: It is used to measure long distances in space</h2>
A light year (
) is a distance unit that is approximately 
.
By definition it is <em>the distance that a photon would travel in vacuum during a Julian year (365.25 days) at the speed of light (299 792 458 m/s) at an infinite distance from any gravitational field or field magnetic.
</em>
<em>
</em>
In other words:
It is the distance that light can travel in a year.
This unit is used to measure large distances in space. Therefore the correct answer is D.
Answer:
by the strong warming and evaporation within the atmosphere around the equator....
