In an undisturbed strata, the oldest layers are at the bottom. It's called the law or principle of superposition.

What part of the sedimentary of rock is the oldest?

Protolith is a term used to describe the parent rock of a metamorphic rock. Conglomerate is a sedimentary rock that can be composed of clasts of sedimentary, igneous, or metamorphic rocks, or any number of combinations of all.


Is The top layer of sedimentary rock is the oldest true or fasle?

True. In an undisturbed sequence of sedimentary rocks, the bottom layer is the oldest and the top layer is the youngest due to the principle of superposition, which states that in any undisturbed sequence of rock layers, the youngest rocks are at the top and the oldest are at the bottom.


What layer of sedimentary rock was deposited first?

The layer of sedimentary rock that was deposited first is typically the lowest layer in a sedimentary sequence, known as the "oldest" layer. According to the principle of superposition, in undisturbed sedimentary rock formations, the layers are arranged with the oldest at the bottom and the youngest at the top. This means that the first layer deposited is usually the one furthest down in the sequence. However, geological events like folding or faulting can complicate this arrangement.


According to the law of superposition the lowest layer in a cross section of rock is what?

According to the law of superposition, the lowest layer in a cross section of rock is the oldest, as sedimentary rocks are typically laid down in sequence with the oldest rocks at the bottom and the youngest at the top.


What can happen to a sedimentary rock?

It is then sedimentary rock.

In layers of undisturbed sedimentary rock the oldest rocks are on the?

Factors such as wind, ice, and warder contribute to sedimentary build up. As this occurs older layers of sedimentary rock are driven lower while newer layers replace them closer to the surface.

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.


Is The top layer of sedimentary rock is the oldest true or fasle?

Is organic rock a type of sedimentary rock?

ORGANIC SEDIMENTARY ROCK`s : Is a type of sedimentary rock because sedimentary rock has three types of sedimentary rock called clastic , chemical , and organic sedimentary rock so yes ORGANIC SEDIMENTARY ROCK is a type of sedimentary rock..........................................


Where are the oldest layers of a sandstone rock located?

Sandstone is a sedimentary rock. Sedimentary rocks form from sediments that deposited by the wind and water. Over the time those sediments will get pressed and cemented together. It can take millions of years for sediments to become a rock. So the oldest layers of a sandstone are on a bottom.


What kind of rock can sandstones be classified as?

Clastic sedimentary rock.


Which rock layer is the oldest and why?

The oldest rock layer is typically found at the bottom of a sequence of sedimentary layers, following the principle of superposition in geology. This principle states that in an undisturbed sequence of rock layers, the oldest layer will be at the bottom and the youngest at the top. Therefore, the rock layer closest to the Earth's surface is usually the youngest, while the rock layer at the bottom is the oldest.
