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.
What else can I help you with?
The type of rocks that form where the remains of plants and animals are deposited in thick layers are called?
The type of rock that forms where the remains of plants and animals are deposited in thick layers are called organic sedimentary rock.
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.
Compare and contrast the compositions of the three different kinds of sedimentary rocks?
The three types of sedimentary rocks pertains to the varying distinctions of land present. Clastic are accumulations of small pieces of broken rock and have been piled and lithified by compaction and cementation. Chemical sedimentary rock form when water evaporates and leaves minerals behind. Thick deposits of salt and gypsum form when constant flooding and evaporation occur over long periods of time. Organic sedimentary rock is the accumulation of debris from organic processes. The shedding of shells, bones and teeth can create a thick enough layer on a seafloor to form a rock, organic, sedimentary base.
How thick is the lithoshere?
The lithosphere, which includes the crust and upper part of the mantle, is typically around 100 kilometers thick beneath the oceans and up to 200 kilometers thick beneath the continents.
The type of rocks that form where the remains of plants and animals are deposited in thick layers are called?
The type of rock that forms where the remains of plants and animals are deposited in thick layers are called organic sedimentary rock.
What do you call the thin and thick part of the crust?
The thin part of the crust is called ocean basins. The thick part of the crust is called continents.
The type of rock deposited in a geosyncline is?
Sedimentary rock is typically deposited in a geosyncline due to the accumulation of sediment over time. This process can result in the formation of various sedimentary rocks such as sandstone, shale, and limestone.
Why is the bedrock of the interior plains so thick?
The bedrock of the interior plains is thick due to a continuous accumulation of sediments over millions of years. Factors such as erosion, deposition, and tectonic activity have contributed to the gradual buildup of sedimentary rock layers, resulting in the thick bedrock found in the region.
How thick is the sedimentary rock in the interior plains?
several of thousands of meters thick
A is marked by its thick sediment accumulation?
continental rise
Is marked by its thick sediment accumulation?
continental rise
What are the thick parts of the earth's crust that form large land masses?
The thick parts of the Earth's crust that form large land masses are called continents. Continents are made up of a variety of rocks and have different geological features such as mountains, plains, and plateaus. There are currently seven continents on Earth.
What is the most abundant sedimentary rock?
The most abundant sedimentary rock is limestone, which is composed mainly of the mineral calcite. It forms from the accumulation of shell, coral, algal, and fecal debris. Limestone is found in many different environments and can vary in color and texture.
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.
Is all sedimentary rock forty thousand feet thick?
No
The oceans are about miles thick under the continents?
50 Miles
