Which of the following factors is not associated with sea-level changes:

a. melting sea ice

b. eustatic changes

c. thermal expansion of ocean water

d. global warming

The answer is B

Explanation:

A is about ice melting lets just say for instance Antarctica started melting the water would raise. And with D and C they both evaporate water, and if you have heard of acid rain there.

b. eustatic changes

Explanation:

The changes in the sea-levels are caused by several factors. The basic factor is the global change in the temperatures, or rather the global warming. With the temperatures being higher across the globe, lot of ice from the ice sheets and glaciers melts, thus increasing the water in the oceans. As this happens, the water gradually becomes warmer and warmer because of the higher temperatures, and the warmer water has bigger volume, thus resulting in further increase of the sea-levels. The eustatic changes can not be taken as factor that cause the sea-level changes because they are what represents the sea-level changes, not what influence them.
