How is limestone rock formed
Limestone is a sedimentary rock made almost entirely of fossils. Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago. Limestone: You humans would know so little without rocks ...Limestone is a sedimentary rock, forming as small particles accumulate on a surface and cement into a solid mass over time. This rock is made from calcium carbonate (CaCO 3 ). You can identify limestone by particular physical characteristics, like the granular texture it forms from pieces of animal shells in the rock.Limestone caves, which are formed primarily by rainwater and snowmelt, are by far the most numerous of all cave types. Limestone formations were created ...

Limestones are composed of calcium carbonate (CaCO₃) and are often produced by organisms, including algae, microscopic organisms called foraminifera, and ...Limestone also accumulates in deeper water, from the steady rain of the carbonate shells of tiny organisms that lived near the ocean surface. The lower limit for limestone accumulation is around 4,000 metres. Beneath that depth, calcite is soluble so limestone does not accumulate. Calcite can also form on land in a number of environments. Siltstone is a sedimentary rock composed mainly of silt-sized particles. It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world. It represents a level of current, wave, or wind energy between where sand and mud accumulate.157 likes, 108 comments - thehistoricreflection on July 30, 2020: "'Into the History' photography contest.
