The appropriate answer is A. the density of ice would be greater than the density of liquid water and so ice would not float. Density can be defined as mass per unit volume. Any substance whose mass is great and occupies a relatively small volume is going to be dense.
Water expands by nine to ten percent when it freezes and this expansion increases the space occupied or the volume and so the density of ice is less than water.
Diverging plate boundaries, earthquakes occur as the plates pull away from each other. Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates. We almost never see these volcanoes, because most of them are located on the sea floor.
