Mineral deposits which develop upwards from a cave floor are known as stagmites. Deposits which form from the ceiling are stalactites.
It's referred to as a Stalagmite or Flowstone deposit.
They are formed by the deposit of minerals. They are left behind by evaporation.
This type of deposit is called a stalactite. Stalactites are made up of calcium deposits from the runoff water coming into the cave.
False
Stalagmite. The opposite, growing downwards from the roof, is a "stalactite".
It's referred to as a Stalagmite or Flowstone deposit.
The ground-water is a solution of calcium carbonate it has dissolved from the limestone above the cave. The mineral is subsequently precipitated as deposits of calcite in the cave: stalatcties & stalagmites, and flowstone on the floor and walls.
I'm not really sure what you had in mind. Given that the cave is in limestone (as the vast majority of them are) there has to be a dimensional limit to the dissolution and erosion processes. The floor is there by default: it is the lowest surface along a passage at that given time in the cave's development.

stalagmite
They are formed by the deposit of minerals. They are left behind by evaporation.
A stone column rising from the floor of a cave is called a stalagmite. It forms over thousands of years as mineral-rich water drips from the ceiling and deposits minerals on the cave floor, gradually building up into a column shape.
This type of deposit is called a stalactite. Stalactites are made up of calcium deposits from the runoff water coming into the cave.
Flowstone. Also if covering a wall or boulder-pile.
False
False
Stalagmite.
