Age of the oldest continental rocks?
The oldest continental rocks are around 4 billion years old. These rocks provide valuable information about the Earth's early history and can be found in regions such as Western Australia, Canada, and South Africa.
What type of rocks are found in a continental shelf?
The rocks found in a continental shelf are often sedimentary rocks, such as sandstone, shale, and limestone. These rocks are formed from the accumulation of sediments on the ocean floor over long periods of time. Additionally, some continental shelves may also have igneous rocks brought up from volcanic activity.
In rock layers what is usually found at the bottom?
In rock layers, the oldest rocks are typically found at the bottom. This is due to the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are deposited first and are at the bottom, while the youngest rocks are at the top.
Rocks in continental crust are as old as years?
Rocks in continental crust can be as old as 4 billion years. This is because continental crust is much older than oceanic crust due to its formation through various geological processes over long periods of time. The oldest rocks found on Earth are typically located in the continental crust.
When rocks eroded they break down into smaller pieces of rocks and minerals called?
Sedimentation
Sediments that consist of mineral grains that were eroded from continental rocks are called .?
hydrates
How would the age of the oldest rock on the continents compare with the age of the oldest rock on the seafloor?
The sea floor is young (the rocks are made at the mid oceanic ridges and spread out form there) while most of the continental rocks are older. This is because the continental crust floats on top of the oceanic crust and is therefore not recycled.

The oldest rock is what kind of rock?

All rocks are made of sediments?
Not all rocks are, only sedimentary rocks are truly made up of sediments. Some metamorphic rocks do because they are formed when heat and pressure are applied to sedimentary rocks, which makes sediments the basis of these rocks as well

What rocks form from the sediments of the other rocks?
Sedimentary rocks.
An exotic terrane created by a seamount accreted to a continental margin would be composed of what?
An exotic terrane formed by a seamount accreted to a continental margin would likely be composed of a mixture of oceanic crust, sediments, and igneous rocks from the seamount. This collision and accretion process can introduce a variety of rock types, such as basalt, volcanic rocks, and marine sediments, which are then incorporated into the continental margin.
When rocks eroded they break down into smaller pieces of rocks and minerals called?
Sedimentation
What is continental depositional environment?
A continental depositional environment is a geological setting on land where sediments accumulate and form sedimentary rocks. Examples include river, lake, desert, and glacial environments. These environments are characterized by unique sedimentary structures and features that reflect the specific conditions under which the sediments were deposited.
