The class of sedimentary rocks made from fragments of rocks, minerals, and shells is called clastic sedimentary rocks.

Here's a breakdown:

* Clastic refers to the fact that these rocks are made up of fragments or clasts.

* Sedimentary indicates that they are formed from sediments that were deposited, transported, and then cemented together.

Examples of clastic sedimentary rocks include:

* Conglomerate: Composed of large, rounded fragments.

* Breccia: Composed of large, angular fragments.

* Sandstone: Composed of sand-sized grains.

* Siltstone: Composed of silt-sized grains.

* Shale: Composed of clay-sized grains.
