Info su questa risorsa...
The formation of stalagmites and stalactites happens through the capillary action between porous rocks and water rich in minerals. The rocks attract the water and the moisture accumulates until gravity forces drops to form. The air evaporates some of the droplet, so that mineral deposits collect and build as additional drops form on top.This project offers an opportunity to observe the gradeual formation of stalactites followed by the reverse build up of stalagmites. When heavier droplets fall from the tip of the stalactite to the ground, evaporation causes the upside down pile of minerals.How are stalagmites and stalactites formed?
