What type of rock is from the cementing small pieces older rocks shells and dead plants animals?

The type of rock formed by cementing small pieces of older rocks, shells, and dead plants and animals 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, and organic matter.

* These sediments can be transported by water, wind, or ice and deposited in layers.

* Over time, these layers are compacted and cemented together by minerals dissolved in water.

Examples of sedimentary rocks that are formed from the cementation of these materials include:

* Conglomerate: This rock is made up of rounded pebbles and larger pieces of rock.

* Sandstone: This rock is formed from sand grains.

* Limestone: This rock is formed from the accumulation of shells, coral, and other marine organisms.

* Coquina: This rock is a type of limestone made up primarily of shell fragments.
