Earth's Frozen Water

Question 1

If every piece of ice that makes up the Arctic and Antarctic ice sheets melted, which statement correctly explains how that water would move through Earth’s water system and what would happen to the oceans?

Accepted Answer

The meltwater would flow into rivers and then into the oceans, raising global sea level by about 70 meters; later some of that water could evaporate and fall as rain or snow elsewhere.

Answer

The meltwater would immediately turn into clouds and stay in the sky, so sea level would stay the same.

Answer

Most of the meltwater would collect in new inland lakes, keeping the rise in sea level under 5 meters.

Answer

All of the meltwater would soak into the ground everywhere, causing only a few centimeters of sea‑level increase.
