What is the thick sedimentary accumulation at the continent's base called?

The thick sedimentary accumulation at the base of a continent is known as the continental crust. This layer is composed of various sedimentary, metamorphic, and igneous rocks that have accumulated over billions of years through geological processes such as erosion, deposition, and tectonic activity.


This layer of the earth's crust is the thickest?

The thickest layer of the Earth's crust is the continental crust, which can be up to 70 kilometers thick. It is found beneath the continents and is primarily composed of granite rocks and sedimentary layers.


A sedimentary rock is 2 m thick. How many years did it take for this layer to form if an average of 4 mm of sediment accumulated per year?

It would have taken 500,000 years for the sedimentary rock layer to form, as 2 meters is equivalent to 2,000 mm and dividing by the accumulation rate of 4 mm per year gives 500,000 years.


A layer of sedimentary rock is 2 meters thick how many years did it take for this layer to form if an average of 4 millimeters of sediment accumulated per year?

It is impossible to derive an answer from the information provided. At first glance it would appear that the answer would be 500 years; in actuality, the sediments that created the sedimentary rock would have been substantially compressed during the lithification process, resulting in a rock thickness that was less than the initial sediment thickness, depending on the type of sediment.


What is the layer of the earth that you stand on and that is a few miles thick?

We live on the crust. It is the thinnest layer of rock.

What is the best estimate of how long it took a thick layer of sedimentary rock to form?

The time it takes for a thick layer of sedimentary rock to form can vary significantly depending on various factors, such as the depositional environment, the rate of sedimentation, and the type of sediment being deposited. In general, it can take anywhere from a few hundred to millions of years for a thick layer of sedimentary rock to form.

How was saltdomes are formed?

Salt domes or diapirs form when thick successions of salt (that formed by evaporation from seawater over long periods of time) start to rise and deform the overlying sediments. Salt rises, because it is less dense than most sedimentary rocks and a thick layer of low density below a thick layer or dense material is mechanically instable.
