Eggzackly! The beautiful property of H2O. Ice is less dense than water, that’s why it floats. And when floating ice melts, creates much less volume than if it were liquid.

Actually, when floating ice melts, it shrinks in volume to equal the volume it displaces, so no change to sea level.

This can be tested, in a glass, in your kitchen.
