The ground is the surface you are painting on, canvas, wood, etc. Many artists tint the ground (a tint is any pigment mixed with white) to add depth to the work.

You can, but it isn't always a good choice. Oil paintings are usually textural, most artists who work in oils build up layers and brush strokes are an integral part of the finished piece. Depending on the amount of texture and the ground (canvas-paper, canvas-board, stretched canvas, or some solid surface, like hardboard) you can sand the painting slightly -if the ground is rigid, then add a coat or two of gesso. In the case of flexible grounds just use gesso, to smooth out the surface and allow to dry. Once the gesso is dry you can paint a new painting over the old one with no worries at all.
The surface is the ground upon which the medium is applied. If you are painting with oils, you are likely using stretched canvas or masonite board as a surface. If you are drawing in pastels, your surface may be Canson paper.
Maps are useful to us in different ways such as providing information of locations or ground quality such as fault structures or existing drainage.
A painting! The surface that an artist works on, be it paper, canvas or other, is called the "ground."

Artists have been painting (oils, acrylic, etc) on canvas for many years. In the case of oil paints, a ground is first laid on the canvas to prevent the (usually) linseed oil in the oil paints from rotting the canvass, which is usually woven from cotton. If this is not the answer expected, then more specific information is needed.
By providing friction against the ground
Paul cezanne encountered many artist now to paint what they think is the best way for them like jackson pollock! Although I don't think that he got encounter by Paul cezanne. Jackson pollock found out he worked better when the canvas was on the ground
