From the shells and skeletons of dead sea creatures.
Chemical limestone can form when calcite is dissolved.
it rains and sinks into limestone and over to starts to corrode at the vulnerable limestone
limestone forms from skeletons and shells
Limestone - sedimentary deposition of calcarious marine organisms. Marble - compressed (metamorphosed) limestone.
Grikes form through the chemical and physical weathering of limestone bedrock by the dissolving action of water. Over time, this weathering process creates deep grooves or crevices in the limestone, resulting in the characteristic appearance of grikes in limestone pavement landscapes.
Chert, a form of quartz, can form as beds or nodules in limestone or dolostone.
Limestone is the rock that is squeezed and heated to form marble. The high pressures and temperatures cause the limestone to recrystallize and become the metamorphic rock known as marble.
Marble is the rock that results from the metamorphism of limestone. Through the process of heat and pressure, the calcium carbonate in limestone recrystallizes to form marble with a characteristic crystalline structure and unique patterns.
