What else can I help you with?
The rock at the bottom of an undisturbed sequence is?
The bottom is oldest. The top is newest. -From bottom to top is the equivalent of oldest to youngest in an undisturbed sequence.
What is the name for the bottom oldest layer of rock?
The bottom layer of rock in a geologic sequence is usually called the basement layer.
What layer of a rock in a mountain is the oldest?
The layer at the bottom of the mountain is typically the oldest, as rocks are usually deposited in chronological order with the oldest rocks at the bottom and the youngest at the top. This principle is known as the law of superposition.
Where would I find the oldest rock on the ocean floor?
The oldest rock on the ocean floor can be found in the central parts of the ocean basins, particularly in regions known as abyssal plains. These rocks are generally around 200 million years old or older.
Is the oldest layer of rock on bottom?
Yes, typically the oldest layer of rock is found at the bottom due to the principle of superposition, which states that in any undisturbed sequence of rock layers, the oldest layer will be at the bottom and the youngest layer at the top. This helps geologists understand the relative ages of rocks and the order in which they were deposited.
The rock at the bottom of an undisturbed sequence is?
The bottom is oldest. The top is newest. -From bottom to top is the equivalent of oldest to youngest in an undisturbed sequence.
On the ocean floor where is the oldest rock?
The oldest rock in oceanic crust is that which is found the greatest distance from a mid-ocean-ridge.
What is the oldest type of rock?
The rock on the way bottom, but not the vein
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.
What is the name for the bottom oldest layer of rock?
The bottom layer of rock in a geologic sequence is usually called the basement layer.
Would the oldest sedimentary rocks be at the top or the bottom of the cliff?
bottom
Where are the oldest rock layers in a syncline?
on th ebottom
What layer of a rock in a mountain is the oldest?
The layer at the bottom of the mountain is typically the oldest, as rocks are usually deposited in chronological order with the oldest rocks at the bottom and the youngest at the top. This principle is known as the law of superposition.
Where would you expect to find the oldest rock on the oldest floor?
Somewhere at the bottom of the Marianas Trench you would find the oldest rock of the oceanic crust. Somewhere else, however, there are older rocks on the ocean floor--those deposited by icebergs that have broken off of glaciers. Those erratic rocks could be much older than the oldest oceanic crust.
When there are fossils in rock layers which are considered the oldest?
the ones closest to the bottom
What is the oldest type of rock at the bottom of the grand canyon?
Vishnu Schist
Where would I find the oldest rock on the ocean floor?
