stalagmites
B
stalactites
C
columns
D
geode
Explanation: 

Detailed explanation-1: -Stalagmite is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate but may consist of lava, sand, mud, pitch, peat, pitch, amberat and sinter.

Detailed explanation-2: -Stalactites hang from the ceiling of a cave while stalagmites grow from the cave floor.

Detailed explanation-3: -As the redeposited minerals build up after countless water drops, a stalactite is formed. If the water that drops to the floor of the cave still has some dissolved calcite in it, it can deposit more dissolved calcite there, forming a stalagmite. Speleothems form at varying rates as calcite crystals build up.

Detailed explanation-4: -Stalagmites and stalactites are some of the best known cave formations. They are icicle-shaped deposits that form when water dissolves overlying limestone then re-deposits calcium carbonate along the ceilings or floors of underlying caves.

Detailed explanation-5: -stalactite and stalagmite, elongated forms of various minerals deposited from solution by slowly dripping water. A stalactite hangs like an icicle from the ceiling or sides of a cavern. A stalagmite appears like an inverted stalactite, rising from the floor of a cavern.
