What else can I help you with?
What type of rocks form in layers and have fossils in them?
sedimentary
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers scientists can learn what?
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers, scientists can learn about the relative ages of the fossils. This helps in understanding the sequence of events in Earth's history and the evolutionary relationships between different species.
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
Why are rock layers significant?
if it is a sedimentary rock the fossils get cemented together
What layer would old fossils be located?
Sedimentary rocks layers.
What can you find within layers of sedimentary rock?
As sedimentary rock is deposited at over time, you can find fossils in it.
Are fossils found in upper layers of sedimentary rocks are older than fossils found in no one there is a sedimentary rocks?
Fossils found in the upper layers of sedimentary rocks are generally younger than those found in lower layers, due to the principle of superposition, which states that in undisturbed layers, older sediments are deposited first and are buried by younger sediments. If there are no sedimentary rocks present, it is impossible to compare their ages directly. Thus, the age of the fossils can vary significantly depending on their specific geological context.
What are forming fossils?
Fossils are formed in sedimentary rocks, which has multiple layers to show the level of soil back then.
Where can you find the oldest fossils in sedimentary rock layers?
The oldest fossils are typically found in the deepest sedimentary rock layers, which are located at the bottom of a rock formation. This principle is known as the law of superposition in geology, where older rock layers are found beneath younger ones.
What are index fossils and how are they used to determine the absolute age of sedimentary rock?
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 kind of rocks would you find fossils in and why?
Fossils are found in sedimentary rock because it is layers of sand, rock, and sediments, and the bones fall between the layers where the form into fossil's.
