Gravity controls the slope.
In spite of the apparent evidence, it is not correct to say that sands take the form of the container. Sand is formed by a large number of small particles of amorphous silicon. The single particle does not change shape when put in the container, for example if it would be cubic it remains cubic. The particles change position one with respect to the other so to fill the container at best due to gravity. This phenomenon is especially evident if the sand is shacked after the container filling. Nevertheless, the container is never completely filled, due to the fact that the shape of the particles is generally not suited to completely fill the container.
well basically anthing that is made out of metal and steel, will move on a scrap heap magnet.
With your MIND.
It is because the the person has a certain amount of energy when he is falling. He has to dissipate all of the energy to come to a stop. The amount of energy absorbed by the contact is equal to the Force times the Distance. The sand allows the person to sink into it when he hits it so the sand requires less Force. When the person hits concrete he does not sink in very a very far distance (in fact it is the person that takes most of the deforming) and so it requires a much greater force to absorb the energy.
The state of matter is actually to states of matter. Solid and liquid are the states of matter that have a volume,(liquid) and shape(solid).
If you drop small particles like sand they roll and form a natural angle. (Just steep enough to be held by friction.) Further particles keep rolling and the angle stays the same. This makes the natural shape.
There is a lone pair.It repels bond and shape become trigonal pyramidal.
It has a lone pair.So it is trigonal pyramidal
Ammonia is a harmful gas. It is pyramidal in shape.
The phosphorus trichloride (PCl3) has a molecule with a trigonal pyramidal form.
Square pyramidal.

Square pyramidal
in XeO3 ,Xe shows sp3 but shape is pyramidal because of the presence of a lone pair of electrons on the central xenon atom. This lone pair distorts the shape of the molecule making it pyramidal.
