Why are sedimentary rocks on the bottom of the oceans younger than similar rocks found on the continents?
== == Sedimentary rocks on the bottom of the oceans are younger because the ocean floor is constantly recycling itself. Oceanic plates are being added to at the oceanic ridge, and being destroyed by subduction when colliding with continental plates. Sedimentary rocks on continents are definitely subject to erosional forces, but not generally to plate destruction forces.

Is the layer of rock at the bottom of a sedimentatry rock younger or older?
The layer of rock at the bottom of a sedimentary rock is older. This is due to the principle of superposition, which states that in an undisturbed sequence of rock layers, the oldest rocks are at the bottom and the youngest are at the top.
What is the theory of sedimntary rock layers tend to be younger and than the layers below them is called?
The theory that sedimentary rock layers are generally younger than the layers beneath them is known as the Law of Superposition. This geological principle states that in an undeformed sequence of sedimentary rocks, the oldest layers are at the bottom and the younger layers are at the top. This ordering helps geologists determine the relative ages of rock formations and the fossils they contain.
What law suggests that older rock strata are at the bottom and younger rock strata are at the top?
The law that suggests that older rock strata are at the bottom and younger rock strata are at the top is the law of superposition. This principle states that in an undisturbed sequence of sedimentary rocks, the oldest rocks will be at the bottom and the youngest at the top due to the natural layering process over time.
Can sedimentary rocks be formed at the bottom of lakes?
Yes, sedimentary rocks can be formed at the bottom of lakes through the accumulation and compression of deposited sediments over time. Processes like lithification can occur in lake environments, leading to the formation of sedimentary rocks such as shale or limestone.
What is the law of the geological principle that states that in horizontal layers os sedimentary rock each layer is ilder than the layer above or below it and younger than the layer below it?
The law you are referring to is known as the Law of Superposition. This principle states that in any undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom, with younger layers deposited on top. As a result, each layer of rock is older than the layer above it and younger than the layer below it, providing a chronological framework for understanding geological history.

Can a moon rock become sedimentary rocks?
no because sedimentary rocks are made at the bottom of oceans
Where do sedimentary rocks from?
Usually on the bottom of a body of water
What rocks formed at the bottom of the sea?
sedimentary rocks
What are rocks formed at the bottom of the sea?
sedimentary rocks
What is a sedimentary rock in which the older rocks unless disrupted are on the bottom?
This type of sedimentary rock is called a "nonconformity." It occurs when younger sedimentary layers are deposited on top of older, often deformed or eroded, igneous or metamorphic rocks. Nonconformities indicate a significant gap in the geological record due to erosion or tectonic activity.
Can sedimentary rocks be formed at the bottom of lakes?
Yes, sedimentary rocks can be formed at the bottom of lakes through the accumulation and compression of deposited sediments over time. Processes like lithification can occur in lake environments, leading to the formation of sedimentary rocks such as shale or limestone.
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 fundamental concept states that in a horizontal sequence of conformable sedimentary strata each higher bed is younger than the bed below it?
The fundamental concept you are referring to is the Law of Superposition. It states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are found at the bottom, while the youngest rocks are found at the top.
