Slate is formed by the effects of heat and pressure on the rocks shale or mudstone. The source of the heat and pressure is usually from depth of burial or tectonic plate collisions, where shale is put under tremendous directional pressure. The pressure causes an alignment of the constituent minerals in the shale, creating a foliated or platy texture, characteristic of certain metamorphic rocks.
A slate is a homogeneous metamorphic rock. Slate composed of clay, sand or volcanic ash. It is a natural product. Being a rock slate is very hard and that can be used anywhere in a house like flooring, roofing etc.

Caves do not form naturally in slate with the possible exception of sea-caves (and then would be inherently unstable) and shallow rock-shelters. Slate mines (entirely artificial) can be very extensive but these are man-made.
