What is the composition of the crust under the continents How do we know?
The composition of the crust under continents consists mainly of granitic rocks (continental crust). We know this through seismic studies that measure the speed of seismic waves traveling through the crust, density measurements, and rock samples brought up from drilling and mountain-building processes.
What is the composition of the crust under the continents How do you know?
The crust under continents is primarily composed of granitic rocks, which are rich in silica and aluminum. We know this through studies of rock samples collected from the Earth's surface and seismic data that provide information about the composition and structure of the crust beneath continents. Additionally, drilling projects such as the Mohole project have allowed for direct observations of crustal composition at depth.
Is the Earth's crust thicker under the oceans or the continents?
Earth's crust is far thicker under the continents.
What type of crust is under the continents?
contianal crust
What is composition of the crust under the continents?
The crust under continents is composed mainly of granite and granodiorite, which are igneous rocks. These rocks are less dense and thicker compared to the oceanic crust, providing the continents with their high elevation and stability. Additionally, the continental crust also contains sedimentary and metamorphic rocks, formed through the processes of erosion and tectonic activity.
Where is the earth crust the thickest?
Under continents
Where is the continental crust located?
Continental crust is located under all continents.
Is the earth crust thicker under the continent or the ocean?
Earth's crust is far thicker under the continents.
Where would crust be the thickest?
The crust is thickest under continents! The crust is thickest under Mount Everest, where it's approx. 65km deep
How do the oceanic and continental crust differ?
Because the oceanic crust is under water in the ocean and a continental crust is land such as the continents
Where is the thickest crust found on earth?
The crust is foundunder the continents the crust is between 32 and 70 km thick the crust is made up of loose rocks and soil under the rocks and soil the crust is solid rock we live on the crust
What is the thinnest under the oceans and thickest through the continents?
the earth's crust
