Limestone. Limestone is the result of the compression of coral, seashells, and other ocean life together. There are two types of limestone, a harder type that is full of calcium, and a softer type with more magnesium. Hard limestone is often used in the building industry, or ground up and used in mortar due to its waterproof quality. Bluestone

Twitter. Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. During metamorphism the calcite limestone recrystallizes, forming the interlocking calcite crystals that make up the marble. Metamorphism occurs in limestone when the limestone is located to convergent plate ...

We can trace the words stalactite and stalagmite back to the Greek word "stalassein," which means "to drip."This is fitting because it describes how both are formed in nature. Although they look lifelike and a little creepy, stalactites and stalagmites grow simply because of water running over and through inorganic material.. Limestone caves, where most stalactites and stalagmites …

Caves are formed by the dissolution of limestone.Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.
