Why gravity dam is called gravity dam ?

Why gravity dam is called a gravity dam? Is there any reason behind the name?

A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by primarily utilizing the weight of the material alone to resist the horizontal pressure of water pushing against it.

Gravity dams are designed so that each section of the dam is stable, independent of any other dam section.

t is called a gravity dam because gravity holds it down to the ground stopping the water in the reservoir pushing it over.

Means I t is due to self weight of dam.. that holds dam in its position and gravity plays role

Gravity dam, as the name suggests, is a dam that resists the water upstream by the use of its weight itself, unlike earthen dams and embankment dams that employ the shear strength of the soil.

The dam is designed so that the resultant of the water pressure, earth pressure, and all other forces are aligned and balanced by the weight of the dam itself.

They are generally made of Roller compacted concrete.
