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.

What is always younger than the rock layers around and beneath it?
Fossils and the organisms they represent are always younger than the rock layers around and beneath them. This is due to the principle of superposition, which states that in undisturbed sedimentary rock layers, older layers are found below younger ones. As fossils are formed from remains of once-living organisms, they can only exist in sedimentary layers that are deposited after their existence. Therefore, they are always younger than the rocks that encase them.
Could a younger layer of sedimentary rock ever be found under an older layer How do you think this could happen?
Yes, a younger layer of sedimentary rock can be found beneath an older layer due to geological processes such as faulting, folding, or erosion followed by deposition. For instance, if tectonic activity pushes older rock layers upwards, younger sediments can be deposited on top of them, or if an area undergoes significant erosion and then new sediment is deposited, the sequence can be inverted. This phenomenon is often seen in complex geological formations where layers have been disturbed.
What principle tells us that in a sedimentary sequence the youngest unit is on the top?
The principle that states the youngest sedimentary unit is on top is called the Law of Superposition. This geological principle asserts that in an undeformed sequence of sedimentary rocks, layers are deposited in a chronological order, with older layers located beneath younger layers. Thus, the most recent deposits will be found at the top of the sequence.
One of the key principles of relative dating is the law of superposition which states that?
Younger layers of sedimentary rock are deposited on older layers
How do you figure out how old rocks are by using their positions compared to each other?
With sedimentary rocks, young ones are usually on top of older ones. Where igneous rocks intrude into others, the intrusions must be younger than the surrounding rocks.

What are the older rocks that lie under younger rocks?
The older rocks that lie beneath younger rocks are referred to as "bedrock" or "subsurface strata." In geological terms, this relationship is described by the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom and the youngest are at the top. These older rocks may include various types of sedimentary, metamorphic, or igneous formations that have been buried and subsequently overlain by newer deposits.

Who is worse older siblings or younger ones?
older ones usually push you around when younger ones nag.
Intrusions of the igneous rock are younger or older than the rock layers beneath and surrounding them?
Intrusions of igneous rock are typically younger than the rock layers they penetrate. This is because the magma that forms igneous intrusions is usually injected after the surrounding rocks have already solidified and formed.
What does the law of superpositioning state?
Principle stating that older rock layers are beneath younger rock layers.
Older workers usually cannot work as effectively as younger workers true or false?
It is false that older workers usually cannot work as effectively as younger workers.
Is an extrusion older or younger than the rock layer below it?
Extrusion is older than intrusion because, an extrusion is always younger than the rocks below it. An intrusion is always younger than the rock layers around and beneath it. Hope the answers correct ;)
What are the risk and disadvantages for a brother of having a younger sister and for a sister of having an older brother?
The older one usually picks on the younger sibling.
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.
One of the key principles of relative dating is the law of superposition which states that?
Younger layers of sedimentary rock are deposited on older layers
