The type of rock made from layers and other materials that are cemented together is called sedimentary rock.

Here's a breakdown:

* Sedimentary rocks are formed from the accumulation of sediments, which are small pieces of other rocks, minerals, or organic matter.

* Layers: These sediments are deposited in layers, often in water bodies like lakes, oceans, or rivers.

* Cementation: Over time, the layers are compressed and cemented together by minerals dissolved in water. This process binds the sediments into a solid rock.

Some examples of sedimentary rocks include sandstone, limestone, shale, and conglomerate.
