How do scientists date sedimentary rock?
They date the igneous intrusions and extrusions near the sedimentary rock layers.
What is special about a sedimentary rock?
Nothing. Scientists have reached consensus that there is absolutely nothing important or special about sedimentary rock. Sedimentary rocks are barely even rocks. Some scientists are pushing to have sedimentary rocks declassified as rocks, and reclassified as extraneous matter.
How do scientists use sedimentary rock to determine a fossils relative age?
Scientists can use sedimentary rock to determine a fossil's relative age by examining the layers in which the fossil is found. The principle of superposition states that in an undisturbed sequence of sedimentary rock layers, the oldest layer is at the bottom and the youngest layer is at the top. By identifying the layer in which the fossil is located, scientists can approximate its relative age compared to other fossils and rock layers.
Which dating method enables scientists to measure or estimate the absolute age of sedimentary rock?
Radiometric dating of igneous rocks that relate to the sedimentary rock
Why do scientists look to sedimentary rocks when studying the history of the Earth?
The vast majority of fossils are found in sedimentary rock.
What makes sedimentary rocks especially useful to scientists and historians?
Sedimentary rock are made of materials that could show what lived where. Also they are the only rock to hold fossils.
How are sedimentary rock layers used be scientists to learn about the past?
plant and animal fossils are most often found in layers of sedimentary rocks
Is organic rock a type of sedimentary rock?
ORGANIC SEDIMENTARY ROCK`s : Is a type of sedimentary rock because sedimentary rock has three types of sedimentary rock called clastic , chemical , and organic sedimentary rock so yes ORGANIC SEDIMENTARY ROCK is a type of sedimentary rock..........................................
What evidence would a scientists use to determine the absolute age of a fossil found in sedimentary rock?
The Igneous intrusions and extrusions near sedimentary layers.
How are sedimentary rock used by scientists to learn about the past?
Sedimentary rock layers are used by scientist help learn by the texture and shapes
What kind of rock can sandstones be classified as?
Clastic sedimentary rock.
What are three examples of semdimentary rock?
Examples of sedimentary rock could be rock on beaches, ocean floor and river beds. These types of rock are formed where types of sediment collect over time. Sedimentary rock is valuable to scientists for they preserve a record of how the earth was was over thousands of years.
