What is likely to be true about the age of rocks in deeper and deeper layers?
In general, rocks found in deeper layers are older than rocks found in shallower layers due to the principle of superposition, which states that younger rocks are usually on top of older rocks. This is based on the idea that sedimentary rock layers are deposited in chronological order over time.
What are older rocks that lie under younger rocks called?
You may be referring to an "outlier" which is an area of older rocks surrounded by younger ones due to faulting and erosion removing layers of younger rocks and forcing older ones up into them. You may also potentially be referring to a xenolith. This is a fragment of older material that has not melted that is trapped within lava or other younger igneous material.
How did scientists discover that rocks farther away from the mid-ocean ridge were older than those near it?
Scientists discovered that rocks farther away from the mid-ocean ridge were older through radiometric dating of the rocks. By analyzing the age of the minerals within the rocks, researchers found that the rocks closest to the ridge were younger, while those farther away were older, supporting the theory of seafloor spreading.
A break that separates older metamorphic rocks form younger sedimentary rocks immediately above them is a type of unconformity called an?
a nonconformity
What is an older rock lie under younger rock mean?
This principle is known as the law of superposition, which states that in undisturbed layers of rock, the oldest rocks are found at the bottom and the youngest rocks are found at the top. Essentially, it is a key concept used in relative dating to determine the relative ages of rock layers.
What older rocks lie under younger rocks?
the answer is the principle of superposition
What is it called when younger rocks are layered on top of older rocks?
superposition
Is it true Older sedimentary rocks are usually found beneath younger ones?
If the strata layers are folded or tilted then the older rocks can be found on top of the younger rocks in a cross-section.
In undisturbed rocks The older rock on the bottom and the younger of the rocks are on top?
yes.
Are the Rocks near axial are younger or older than the rocks in Oregon?
What is axial?
What is supersition?
It says the younger rocks lie above older rocks if the rocks have not been disturbed .
How can older rocks be found above younger rocks in a cross section?
There are two possible explanation. In one cases the underlying younger rock could be an igneous intrusion, formed when molten rock was injected into pre-existing rock and then cooled. Another explanation might be that the beds were overturned as the rock was deformed and tilted.

In general, rocks found in deeper layers are older than rocks found in shallower layers due to the principle of superposition, which states that younger rocks are usually on top of older rocks. This is based on the idea that sedimentary rock layers are deposited in chronological order over time.
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 older rocks that lie under younger rocks called?
You may be referring to an "outlier" which is an area of older rocks surrounded by younger ones due to faulting and erosion removing layers of younger rocks and forcing older ones up into them. You may also potentially be referring to a xenolith. This is a fragment of older material that has not melted that is trapped within lava or other younger igneous material.
How old are rocks found in Apollo missions?
The moon rocks are older then the rocks found on earth.
Why are the oldest fossils sometimes not on the bottom layers of rocks?
Older fossils may not always be found at the bottom layers of rocks due to geological processes like folding, faulting, or erosion, which can disrupt the original order. In these cases, older fossils may be found at higher layers while younger fossils are found in lower layers.
