Rocks made from larger pieces of sediment are called clastic sedimentary rocks.

Here's why:

* Clastic refers to the fact that the rock is made up of fragments (clasts) that were once part of other rocks.

* Sedimentary indicates that the rock formed from the accumulation and cementation of sediments.

Examples of clastic sedimentary rocks include:

* Conglomerate: Made of rounded gravel-sized clasts.

* Breccia: Made of angular gravel-sized clasts.

* Sandstone: Made of sand-sized clasts.

* Mudstone/Shale: Made of clay-sized clasts.
