sedimentary rock made of calcium carbonate
A type of light-colored rock made mostly from calcium, often formed in the sea, that is used to make buildings, roads, and other materials.
用法パターン：
limestone [rock/cliff/building/soil]
よくある間違い：
Learners sometimes treat 'limestone' as a regular countable noun and say *a limestone* when they should say 'a piece of limestone' or 'a block of limestone'. Another confusion is thinking that 'limestone' and 'chalk' are always the same; chalk is actually a specific soft type of limestone.
類義語
calcium carbonate rock (More technical and explicit about the chemical composition; less common in everyday speech.)

chalk (A softer, fine-grained form of limestone; only a synonym when referring to that specific type of limestone.)
