Los cristales en las cuevas

The video explains how rainwater, by absorbing carbon dioxide, forms carbonic acid that dissolves limestone, creating caves. Over time, these caves develop structures like stalagmites and stalactites through processes like nucleation, where ions form crystalline structures. The video highlights the slow growth of these formations over thousands of years.

What role does carbonic acid play in the formation of caves?

• It forms stalagmites.

• It evaporates the water.

• It dissolves the limestone.

• It strengthens the limestone.

What happens when a solution in a cave becomes saturated with calcium compounds?

• Ions begin to collide and form a crystalline structure.

• The cave collapses.

• The solution becomes acidic.

• The solution evaporates completely.

What is nucleation in the context of cave formations?

• The dissolution of limestone.

• The arrangement of ions into a crystalline structure.

• The formation of sound waves.

• The process of water evaporation.

What are stalagmites and stalactites primarily composed of?

• Sandstone

• Basalt

• Granite

• Calcite

Why might there be many undiscovered caves with crystals?

• They are isolated from the world.

• They are too small to notice.

• They are underwater.

• They are located in urban areas.
