Sedimentary rocks, after being buried, can turn into metamorphic rocks. This happens through a process called metamorphism.

Here's a breakdown:

* Sedimentary rocks are formed from the accumulation and cementation of sediments like sand, mud, or organic matter.

* Metamorphism is the process of changing existing rocks (including sedimentary rocks) by heat, pressure, and/or chemically active fluids. These conditions exist deep within the Earth's crust.

* Metamorphic rocks are the result of this transformation. They have a different texture and mineral composition than the original sedimentary rock.

Examples of metamorphic rocks formed from sedimentary rocks:

* Marble formed from limestone

* Slate formed from shale

* Quartzite formed from sandstone

The depth and duration of burial, as well as the specific conditions of heat, pressure, and fluids, determine the type of metamorphic rock that forms.
