Those are stalagmites. It has a 'g' in it, so think of 'Ground' to help you remember.
The deposits hanging from the roof of the cave are stalactites. It has a 'c' in it, so think of 'Ceiling'. They also Stick Tight to the ceiling.
STALAGMITES
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.
In theory yes, if the caves' formative stream cuts down to the insouble basement under the limestone. The visible floor ofa cave is often not the host rock, but sediments, boulders, etc covering the true floor.
Stalactites grow down the ceiling.Stalagmites grow up from the floor.A good way to remember: C for Ceiling, G for Ground.If they meet they form a Column!
A shawl is a calcite formation and forms when water runs down a gentle slope rather than falling straight to the floor. See the link below for a good picture taken in the Jenolan caves near Sydney, Australia.
Mineral deposits which develop upwards from a cave floor are known as stagmites. Deposits which form from the ceiling are stalactites.
Stalac"tites", top, or on the roof of the cave. Stalagmites form on the floor of caves.
Stalagmites
Stalagmites, which are found in caves, are cone-shaped formations of calcium deposits made by calcium concentrated water dripping through the cave ceiling and onto the floor of the cave. Once the water evaporates, solid calcium is left behind thus forming a stalagmite. These deposits form like an icicle hanging from the cave roof.However not to be confused with a stalactite (which is a cone-shaped calcium deposit hanging from the ceiling of a cave), stalagmites are cone-shaped icicle formations of calcium deposits that build upward from the cave floor.
what are the aswer
Limestone, like the walls and roof.
A stalactite is a structure that hangs from the ceiling of a cave and is formed by the precipitation of minerals from dripping water.
Caves wouldn't have much soil. It would mostly be a rock floor with fallen rocks, stones, pebbles from above.
STALAGMITES
hang from the ceiling
Down from ceiling
On the floor! E.g. in hollows where dripping water can accumulate. Often in streams as in surface streams. Or as "gour pools" (aka in USA, I think, "rimstone pools") - formed by calcite deposits forming natural weirs in the trickle of water flowing through them. These can be very beautiful.
