sand grains
Sedimentary rocks can be comprised of rock fragments along with cementing minerals. These are referred to as clasticsedimentary rocks. Some sedimentary rocks, however, are not composed of rock fragments. These non-clastic sedimentary rocks have formed from the precipitation of minerals from fluids, or from the compaction and cementation of certain organic materials over long expanses of time.
some rocks are, but those are a specific kind of rock. (a sedimentary rock is made of grains and or sediment, others are from hardened lava and pressure underground)
Clastic sedimentary rock is made from cemented weathered, eroded, deposited, and compacted particles of pre-existing rock.
Clastic and chemical sedimentary rocks are composed of grains of minerals or particles of pre-existing rock. Organic sedimentary rock is composed of material from organic processes.
Sedimentary rocks are made from weathered down materials, often rocks, so they can be argued that they come from other rocks. Metamorphic rocks are formed from pre-existing rocks; these rocks go under extreme heat and pressure. In conclusion, metamorphic rocks are definitely made from other rocks, and sedimentary rocks are sometimes made from other rocks. Sedimentary rocks are always made of other rocks,extrusive and intrusive igneous rocks as well as metamorphic rocks are weathered and eroded by agents like water , wind and sunlight and are stratified and compacted to form sedimentary rocks. Hence, even if metamorphic rocks are made from rocks, sedimentary rocks are definitely made from other rocks. Eg: sedimentary rock shale gets metamorphosed into slate and further metamorphosed into shcist which is the parent material of granite which can be effected by agents of weathering and erosion into sedimentary rocks again.
A sedimentary rock made up of rock fragments or particles of other rocks is called 'clastic'.

Sedimentary rocks that are made from compressed plants are called biologic sedimentary rocks. Accumulated carbon-rich plant material can result to the formation of coal.

Sedimentary rocks
Clastic sedimentary rocks are made of broken pieces of preexisting rock that are compacted together. The mineral quartz makes up sixty percent of the clastic sedimentary rocks.

It is said to be a clastic sedimentary rock.

There are different ways sedimentary rocks are formed. Many sedimentary rocks are made from the broken pieces and particles of other rocks, [which is a reason why the name was given to these types of rocks (sediment)] and these bits get cemented together. These types of sedimentary rocks are called clastic sedimentary rocks. Chemical sedimentary rocks are another type that comprise of mineral crystals, like gypsum and halite. Lastly, organic sedimentary rocks are made of, well...... organic materials. They are made of the remains of once living organisms and contain the remains of living creatures such as clam shells, plankton skeletons, dinosaur bones, and plants.
Sedimentary rocks are made out of sediments.

they are called sedimentary rocks... yeah that worksheet made me mad... glenco stinks
Many sedimentary rocks are made from the broken bits of other rocks. These are called clast sedimentary rocks. The broken bits of rocks are called sediment. Sediment is the sand you find at the beach, the mud in a lake bottom, the pebbles in a river, and even the dust on furniture. The sediment may, in time, form a rock if the little pieces become cemented together
The rock that forms in layers of small pieces is called sedimentary rock. It is made up of fragments of other rocks, minerals, or organic material that have been weathered and transported by wind, water, or ice before settling and lithifying into solid layers. Examples of sedimentary rocks include sandstone, shale, and limestone.
