Question

1. which rock or mineral is composed of more than one sediment?

Explanation:

Sedimentary rocks like conglomerate are clastic sedimentary rocks formed by cementing together multiple types of sediments (such as pebbles, sand, and silt, which are different sediment sizes/particles). Minerals are single, naturally occurring crystalline substances, so they are not made of multiple sediments. Conglomerate is a clear example of a rock composed of more than one sediment type.

Answer:

Conglomerate (a clastic sedimentary rock; it is made up of rounded gravel-sized sediments, sand, and finer silt/clay sediments that are cemented together)
