măng đá

Trong hang động, một cột măng đá cao nhô lên từ nền đá.

Definition

1. Noun:
   • Stalagmite: A mineral formation, typically composed of calcium carbonate, that rises from the floor of a cave. It is formed by the dripping of mineral-rich water from the ceiling, with deposits building upwards over time.

Usage Examples

• Noun:
  • Trong hang động, những cột măng đá trông rất hùng vĩ. (In the cave, the stalagmite columns look very majestic.)
  • Măng đá và nhũ đá đôi khi nối liền tạo thành cột đá. (Stalagmites and stalactites sometimes join to form a column.)

Advanced Usage

• The term is used in geological and geographical contexts to describe speleothems (cave formations). It is often discussed in contrast to "nhũ đá" (stalactite), which forms from the ceiling downwards.
