Sedimentary rocks can be formed only where sediments are deposited long enough to become compacted and cemented into hard beds or strata. They are the most common rocks exposed on the Earth’s surface but are only a minor constituent of the entire crust. Their defining characteristic is that they are formed in layers.

Do you think all sedimentary rocks look the same?

No, all sedimentary rocks do not look the same. Sometimes you can even see different layers in sedimentary rocks. These types of rocks feel grainy, like sand, and are easier to crumble than other types of rocks.

Are sedimentary rocks soft or hard?

What is the color of sedimentary rocks?
