==Formation of Chalk== | ==Formation of Chalk== | ||
Chalk is formed through the accumulation of microscopic marine organisms, such as coccolithophores, which secrete calcium carbonate shells. Over time, these shells accumulate on the ocean floor, forming layers of sediment that eventually solidify into chalk rock. | Chalk is formed through the accumulation of [[microscopic marine organisms]], such as [[coccolithophores]], which secrete calcium carbonate shells.
