This would be a sedimentary rock, a more precise name would require the size of the sand and mud grains as well as the amount of sand and mud, and if there are any fossils, or siliceous or carbonate cementing of grains.

∙ 13y agoSedimentary rock. As the name implies, sedimentary rocks are formed when sediment accumulates in layers and is then subjected to pressure for enough time to harden into rock. The sediment can be small bits of other rock (which is what sand and mud are), plants, or animals. Sand, and mud form rocks such as sandstone, conglomerate (sandstone with small pebbles mixed in), and shale. Plants and animals may form fossils in various kinds of sedimentary rocks, or may form coal or limestone (depending on the type of plant or animal and environmental conditions).
The pressure often comes from water on top of the sediment (sediment sinks and accumulates wherever streams or rivers flow into bodies of calmer water), but can also come just from the additional sediment that accumulates on top.

What kind of rock has layers and is made from small grain?
That is correct. A detrital (or "clastic") sedimentary rock is formed by sediment grains that have been weathered and eroded by existing rocks and then deposited as layers.
Why does gravity cause layers of sediment to be horizontal?
As more sediment is added, it is compressed and hardens into rock layers.
Rock type that is formed when sediment is lithified?
Sedimentary rock can be formed from lithified sediments.
What is the process by which layers of sedimentary rock are formed?
The process by which layers of sedimentary rock are formed is called strata.
Would you expect to find a well preserve dinosaur bone in a metamorphic rock like schist?
NO, a metamorphic rock is a new rock formed when existing rockes are spueezed or heated. If you were to find a dinosaur bone in a rock it would be a sedimentary rock, which is a rock formed by layers of sediment, Which means a dinousar bone could of been on top of a layer of sediment and another layer of sediment went on top of that, formed a rock that had a dinosaur bone in it.
When sediment is deposited in layers what rock is formed?
sedimentary
When sediment is deposited in layers what rock is formed explain your answer?
sedimentary
How do layers in sedimentry rocks form?
The land where the rock was formed was underwater when the rock was formed. Over the years layers of Sediment sank to the bottom. Pressure formed the sediments into rock.
What is organic sedimentary?
a rock formed by unconsolidated sediment deposited in layers
When sediment is deposited in layers and compacted?
...sedimentary rock is formed. OR ...strata is formed. Try either.
Why was sedimentary rock named sedimentary rock?
Because the rocks are formed by using layers of Sediment.
Rocks that have layers or clasts were formed by what?
Is it sediment being compressed until it becomes rock
How are layers formed in a Sedimentary Rock?
The layers are formed by the deposition of sediments carried by wind, water, or ice.
What type of rock forms from layers of sediment?
Sedimentary rock.
What is a sedimentray?
A rock composed of layers of sediment.
What is a dark sedimentary rock formed by compression of layers of clay-rich sediment?
Shale is made from layers of mud and clay pressed together. :)
Why is rock gypsum a sedimentary rock?
Gypsum is a mineral that was formed by layers of sediment , fine particles, that were deposited over a period of time, and then subjected to geologic forces.
