Marble is most commonly white and has a sugary texture but it can change when limestone recrystallizes. Marble forms when limestone is under heat and pressure from the metamorphic process. Magma from up above closer to the Earth’s surface activates the metamorphism of limestone. Sandstone is a “sedimentary rock made of sand sized grains of mineral‚ rock‚ and other organic material” (Sandstone‚ 2017). Sandstone has a rough‚

The malleability of the plaster is important as it allows the artist to create this level of realism that would be tough to achieve with just limestone.

floating through the ocean‚ and there are actually many different species of foraminifera‚ some even reside on the sea floor. The foraminifera grows by creating more space in their limestone shells. They’re only about the size of one grain of sand. The foraminifera can obtain energy by expanding its gooey arms out of the limestone encasing to trap smaller organisms. The mutualistic symbiotic dinoflagellates increase primary productivity. This is done by the foraminifera moving the algae onto the arms

The element calcium’s name first originated from the Latin name “calx” which means “lime”. It was first discovered in England during the year 1808 by Sir Humphry Davy. He was able to separate calcium into a pure metal by doing an electrolysis process on a mixture of lime HgO‚ which is mercuric oxide. However‚ Sir Humphry Davy was not able to do this until after he found out Berzelius and Pontin electrolysed lime into mercury which constructed calcium amalgam. Although he discovered calcium in 1808
