Sedimentary rock made from layers of dead plans is called?
If the layer is of dead plants, it is a compressed layer known as a coal seam.
Suppose a lava flow was found between two sedimentary rock layers How could you use the lava flow to learn about the ages of the sedimentary rock layers?
Because of geologic events such as plate tectonics and volcanism, suitable material for radiometric dating, such as volcanic tuff, solidified lava, and igneous intrusions have been found as layers on, in, and cut through layers of sedimentary rock.Intrusions are always younger than the rock body they penetrate, meaning that the sedimentary rock in which intrusions are found will be older than a radiometrically dated sample of the intrusion. Lava flows and volcanic ash which form layers in rock will be younger than the rock below and older than the rock above. The solidified intrusions and lava flows can be dated with radiometric techniques.The radiometric dating of suitable rocks (i.e. igneous or metamorphic) in proximity to their sedimentary counterparts, therefore allows the sedimentary rock to be dated as well.
What rocks are formed by compressed sediments?
Sedimentary rocks like sandstone, shale, and limestone are formed when layers of sediments are compacted and cemented together over time. This process is known as lithification.
When rock fragments get compressed and hardened to form layers of rocks they are known as?
metamorphic rocks
Sedimentary deposits built into relatively regular layers are known as?
Strata.
What kinds of rocks are simular to layers of cake?
A rock composed of compressed layers (sometimes resembling a cake) are known as sedimentary.
Igneous intrusions injected between horizontal layers are?
These are known as sills.
How can one create a sedimentary rock?
To create a sedimentary rock, layers of sediment such as sand, mud, or minerals must be deposited and compressed over time. This process, known as lithification, involves the compaction and cementation of the sediment layers to form a solid rock.
Sedimentary rock made from layers of dead plans is called?
If the layer is of dead plants, it is a compressed layer known as a coal seam.
What is the most noticeable characteristic of sedimentary rock?
The most noticeable characteristic of sedimentary rock is its layered appearance, which is known as "bedding." These layers are formed over time as different sediment deposits accumulate and are compressed together.

Can Layers and layers of dirt that is pressed down form into sedimentary rock?
Yes, layers of dirt, also known as sediment, can be compacted and cemented over time to form sedimentary rock through a process called lithification. This process involves the particles being compressed and solidified by pressure and mineral growth, resulting in the formation of sedimentary rocks like sandstone, shale, and limestone.
What are the Igneous intrusions injected between horizontal layers known as?
Igneous intrusions injected between horizontal layers are known as sills. Sills are tabular intrusions that are typically parallel to the layering of the existing rock formations. They are formed when magma is injected horizontally into existing rock layers and solidifies underground.
What rocks are formed by compressed sediments?
Sedimentary rocks like sandstone, shale, and limestone are formed when layers of sediments are compacted and cemented together over time. This process is known as lithification.
What are the particles in sedimentary rocks called?
Sedimentary rocks are made from particles called sediment. They are made from layers of sediment (small particles) on the bottom of rivers or seas. The sediments are compressed as more layers build on top of them. The particles then become cemented together to form solid rocks. The layers of rock are called strata. Sedimentary rocks have a grainy structure and they easily crumble.
What is the building up of layers of sediment?
The building up of layers of sediment is known as sedimentation. This process occurs when particles of rocks, minerals, and organic matter settle and accumulate on the Earth's surface over time, forming layers of sediment. Over millions of years, these layers can become compressed and cemented together to form sedimentary rocks.
When rock fragments get compressed and hardened to form layers of rocks they are known as?
metamorphic rocks
