How A Cave Forms
It is somewhat crazy that raindrops-many trillions of them over hundreds of thousands of years-helped build these cave formations, of minerals deposited within a cave. This is how it happened rainwater actually carved the cave out of solid rock .The rock under these mountains can be dissolved, or eaten away, by a mild acid found in rainwater. This will form a cave chamber. When the water oozes into a cave, it carries minerals from the soil and rock above and deposits them on the cave’s wall, ceilings, and floor the minerals build up over time and become a cave formations.
Stalactite- the rocky formation that hang from the cave’s roof or stalactites. Water that has drip into the cave is deposits minerals of the cave’s ceiling. Over millions of years, this builds up to form a stalactite.
Flowerstone – Flowerstone forms the same way a stalactite or stalagmite does: water over the walls and formations, releasing its minerals as it goes.
Stalagmite – dripping water on cave’s floor, over time a stalagmite will form. The droplets splash and spread as they hit the floor of the cave, stalagmite are usually wider and rounder then slender, pointed stalactites.
Column – When a stalactite and a stalagmite grow together, they form a column. Once a column forms, the water flowing over it can deposit flowstones on it. That is why some column can grow to massive size.
- Water seeps through the ground and picks up minerals that will make it mild acid. The groundwater will enter cracks in the rock making them wider.
. 2 When the cracks become large enough underground rivers begin to flow threw them. The flowing water erodes the rock even more.
3 If there is air, in the caves, droplets of water deposit minerals on the celling and the floor. Over time, these deposits grow larger to make cave formations.
