Chemistry - Reactions - Learning Points. Caves are a result of rainwater slowly carving away rock. Carbonic acid forms in rainwater as it passes through air and soil, and this dissolves calcium in limestone rock. Crystals in caves form from a high concentration of ions in a calcium solution. Stalagmites and stalactites are the two common crystal formations. A Twig Context Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts in action in the real world.\n
