What is the relationship between sedimentary rocks and fossils?
When sedimentary rocks grow more layers small fossilised animals get caught between the layers. Ther fore when people chip away at the rock or erosion happens the fossilisd animals have been turned into fossils and fall out.
How do sedimentary rock layers provide clues to a fossil age?
because fossils are in sedimentary rock
How is a sedimentary rock with fossils formed?
Sedimentary rock (limestone, slate, etc) forms when small particles sink onto the seabed, along with dead animals or plants, forming deep layers of mud. Over a very long time, the lay may be subjected to enough pressure to form sedimentary rock, encasing the fossils.
Are there 2 facts about sedimentary rocks?
The two main features of sedimentary rocks are: They are formed into strata or layers. They consist of many palaentological evidences like fossils and coal.
What are index fossils and how are they used to determine the absolute age of sedimentary rocks?
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
What type of rocks form in layers and have fossils in them?
sedimentary

Are sedimentary rocks characterised by having layers and fossils?
Yes
Where is most fossil evidence found?
Fossils are found most commonly in layers of sedimentary rock. This type of rock begins to form when water and wind form layers of sand and silt.
How do sedimentary rock layers provide clues to a fossil age?
because fossils are in sedimentary rock
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
What layer would old fossils be located?
Sedimentary rocks layers.
Why are rock layers significant?
if it is a sedimentary rock the fossils get cemented together
What can you find within layers of sedimentary rock?
As sedimentary rock is deposited at over time, you can find fossils in it.
Where can you find the oldest fossils in sedimentary rock layers?
It would be found in the lower layers, rather that younger fossils which are found in the upper layers. ♥
What does the rock cycle have anything to do with fossils?
Sedimentary rocks are rocks that are formed by layers of different things compacting very tightly. These layers can have a lot of different things in them, like fossils. So, sedimentary rocks are partially made up of fossils.
What are forming fossils?
Fossils are formed in sedimentary rocks, which has multiple layers to show the level of soil back then.
