Cách sử dụng
The word 'sedimentary' describes rocks that are made from small particles that settle at the bottom of a body of water or on land over a very long time. For example, sandstone or limestone are sedimentary rocks. The word can also be used to describe sedimentary layers in soil or sedimentary deposits in water or other liquids. So, if someone is talking about rocks, soil or deposits that have formed over time from layers of sediment, they might use the word 'sedimentary'.
