タイトルまたは説明

Limestone is a sedimentary rock composed mostly of calcite and aragonite. Many limestones are composed from skeletal fragments of marine organisms, such as coral or foraminifera. Limestone makes up roughly *0 percent of total volume of sedimentary rocks. Limestone is formed by sediment from the bottom of the ocean and skeletal remains from animal life and also plant waste comprised over thousands of years.

Other limestone is formed from evaporated water, which left behind deposits. These deposits form stalagmites and stalactites in moist caves. Limestone can be compressed for thousands of years in the ocean, until pressure pushes the limestone through the water and unto land to form hills, turrets and also towers.
