WebThe greater the weathering of limestone, the more CO2 is removed from the atmosphere. As limestone dissolves faster than silicate rocks, the chemical weathering of limestone accounts for more of the total chemical erosion of the land surface than any other rocks, even though much larger areas of the Earth consist of silicate rocks.

WebTwo important steps are needed for sediments to lithify. Sediments are squeezed together by the weight of overlying sediments on top of them. This is called compaction. Cemented, non-organic sediments become clastic rocks. If organic material is included, they are bioclastic rocks. WebFossiliferous limestone contains many visible fossils. A type of limestone called coquina originates from beach sands made predominantly of shells that were then lithified. … WebA fossil is the preserved remains or traces of a dead organism. The process by which a fossil is formed is called fossilisation. It’s very rare for living things to become fossilised. dwarf monterey cypress
