GEOLOGY

Detailed explanation-1: -They are icicle-shaped deposits that form when water dissolves overlying limestone then re-deposits calcium carbonate along the ceilings or floors of underlying caves. Stalactites form along ceilings and hang downward. You can remember this with the phrase “Stalactites hang TIGHT to the ceiling.”

Detailed explanation-2: -Stalactites hang from the ceiling of a cave while stalagmites grow from the cave floor.

Detailed explanation-3: -As the carbon dioxide is released, calcite is precipitated (redeposited) on cave walls, ceilings and floors. As the redeposited minerals build up after countless water drops, a stalactite is formed.

Detailed explanation-4: -A stalactite is an elongated structure of minerals formed and hanging from the ceilings of caves, hot springs, or man-made structures such as bridges and mines. They are deposited from a solution of minerals in the water, slowly dripping from the ceilings.

Detailed explanation-5: -The chemistry of limestone stalactites Stalactites and stalagmites form when rainwater drips through limestone rock.
