It depends on depth.
The pressure that a fluid exerts depends on the density and the depth of the fluid.
We say the liquid exerts pressure on the object.

By increasing the area of cross section in contact with the ground
It is not the weight of the immersed object but the volume of the object would affect the buoyant force on the immersed object because the buoyant force is nothing but the weight of the displaced liquid whose volume is equal to that of the immersed object.

It is upthrust. Any fluid exerts force on an object dispersed in it. According to Archimedes principle, the force exerted by a fluid on an object is equal to the weight of the fluid dispersed by it.

The object that exerts gravity is an object with mass.
-- volume of the object immersed in fluid -- density of the fluid in which the object is immersed
When something exerts a force on an object, that object exerts an equal and opposite force on the other object.
This is called a "bouyant" force. It is due to the difference in water pressure between the top of the object and the bottom of the object. Water pressure increases with depth.
Of exactly the same magnitude but in the opposite direction.
It means that if one object exerts a force on another object, the other objects exerts a force back on the first object.
