Question

Choose the correctly matched cave feature and its formation:

• A. Stalagmite - Formed by dripping water from cave ceiling
• B. Pillar Hangs from the cave roof
• C. Stalactite - Formed by upward mineral flow
• D. Stalactite - Grows upward from cave floor

Answer 1

Answer:

A. Stalagmite - Formed by dripping water from cave ceiling

• Stalagmites are cave formations that grow upwards from the cave floor.

• They are formed by the deposition of minerals, primarily calcite, from dripping water.

• When water containing dissolved calcium carbonate drips from the cave ceiling (often from stalactites), it loses carbon dioxide to the cave air.

• This process causes the calcium carbonate to precipitate out of the water, forming a small deposit on the floor.
