Question

question: what type of structure forms when a speleothem on the ceiling of a cavern meets with a speleothem on the floor of a cavern? answer options: select one of four flowstone stalactite limestone column stalagmite

Explanation:

To solve this, we analyze each option:

• Flowstone: Forms from flowing water depositing minerals, not from meeting ceiling and floor speleothems.
• Stalactite: Grows from the ceiling (hanging down), not formed by meeting with a floor speleothem.
• Limestone column: Forms when a stalactite (ceiling) and stalagmite (floor) grow and meet, connecting them into a column.
• Stalagmite: Grows from the floor (upward), but alone doesn't form from meeting a ceiling speleothem.

Answer:

Limestone column
