Mainly because the fossils of plants and animals preserved in the sediment layers allow dating of events that happened before humans existed.
What else can I help you with?
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.
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.
Radiometric dating is least useful for dating what type of rocks?
Radiometric dating is least useful for dating sedimentary rocks because they are formed from the accumulation of sediments, making it difficult to determine the original isotopic composition.
Why do scientists look to sedimentary rocks when studying the history of the Earth?
The vast majority of fossils are found in sedimentary rock.
Sedimentary rocks are useful as records of past time because of .?
Their layered structure :)
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
Why are sedimentary rocks important to scientists?
Answer: Sedimentary rocks contain the entire history of life on earth that is available to us, and much of the history of the Earth itself. All of this information will help us determine how we got where we are today.
What do scientists classify rocks into what one of the three main categories by?
Scientists classify rocks into three main categories - sedimentary, igneous, and metamorphic - based on how they are formed. Sedimentary rocks are formed from the accumulation and solidification of sediments, igneous rocks are formed from the cooling and solidification of magma or lava, and metamorphic rocks are formed from the alteration of existing rocks through heat and pressure.
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
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 is radiometric dating less useful to date sedimentary rocks than igneous rocks?
Radiometric dating is less useful for dating sedimentary rocks because they are made up of material that has been transported and deposited from other sources, making the age of the sedimentary rock different from the age of the material within it. Igneous rocks directly crystallize from magma and accurately retain the age of their formation through radiometric dating.
