Answer: D. Sea level drops when water is stored in expanding ice sheets and continental glaciers.
Explanation:
One of the most important and influential factors in the change in sea level is the change in the amount of ice that covers the Earth. This is because much of the planet's fresh water is stored in glaciers and ice sheets.
Then, the more water exists in solid state in glaciers and ice sheets, the lower the sea level. However, today the opposite is happening, due to the accelerated climate change, which has caused the melting of glaciers and sea level rise.
