Mountains are supported by the Earth's crust, which is less dense and floats on the denser mantle beneath. The crust is buoyant and supported by the strength of the rocks and tectonic processes that lift and maintain the mountains at the surface.
Buoyant force.
The force that balances the downward force of gravity on a swimmer is buoyant force. This force is exerted by the water on the swimmer and allows them to float or stay afloat in the water.
Buoyant force can be determined by calculating the weight of the fluid displaced by an object submerged in it. The buoyant force is equal to the weight of the fluid the object displaces, and it acts in the opposite direction to gravity. This force helps objects float in a fluid.
When something floats, the buoyant force (upward force exerted by a fluid that opposes the weight of an immersed object) is equal to the weight of the object. This balance of forces allows the object to stay afloat without sinking or rising.
The force of inertia keeps water in a bucket when you swing it.

The force that keeps all of our planets in rotation is gravity.

This answer may not be too technical but you will get the general concept. Generally buoyant force is the force which help the objects to float in fluids which includes water and air without sinking. From this its clear that it acts in the direction opposite to the gravity force to make the object float. Gravity is the force that keeps things gown on earth Thus its called the anti gravity force.
It keeps their feet from sinking into the shifting sands common in the desert.

The mantle's heat is primarily maintained through the decay of radioactive elements within the Earth's core, which generates thermal energy that keeps the mantle molten. Additionally, heat from the core and the mantle's own internal heat contribute to maintaining the mantle's temperature and preventing it from cooling down and solidifying.
We do not sink into the Earth because the ground beneath us exerts an equal and opposite force, called the normal force, that counteracts gravity. This balance of forces keeps us from sinking further into the Earth's surface.
