Standing on the top of a concave slope means you can not see down to the bottom due to the bulge in the middle. A concave slope starts gently and gets steeper, once over the bulge, near the bottom. Standing on a concave slope means that you can see the bottom of the slope. A concave slope starts off steeply and becomes less steep near the bottom.
the top is the giver while the bottom is the receiver
the difference between them is that the bottom face is different one of them is a rectangle and one of them is a square
The sandy-bottom is all sand, and the live-bottom is plant life.

Surfboard has a sharp keel on its bottom while the ski bottom is smooth.
The bottom is the sols and there better looking
There is one basic difference between a footnote and an endnote: where it is placed. A footnote is at the bottom of a page and an endnote is at the end of a document.
The difference is that a female has a white bottom and a male does not.
I have an old soda bottle which reads "Excelsior Bottling Works, Schenectady, NY" on the side and also has a "Q" on the concave bottom. It was estimated to have been produced between 1875-1895.
The only alternative to a concave bottom would be a flat bottom, as a convex bottom would not let the can stand up properly. The flat bottom can would:1. be weaker that a curved surface2. Deform with the pressure in the can and lead to instability.3. The concave surface overcomes both of these problems, allowing for stability when the liquid is pressurized and also added strength.
Since the contents are under pressure, the bottom of the can cannot be flat. If the bottom of the can was flat, the pressure could cause the bottom to deform, and then the can could not stand upright. The concave surface provides a firmer surface to withstand the pressure within the can.
