What else can I help you with?
In earths crust What type of rock is found under the oceans?
Oceanic crust, new oceanic crust is produced by seafloor spreading.
What makes up the bedrock under the oceans?
The bedrock under the oceans is primarily composed of basalt, a type of volcanic rock that forms from the solidification of magma beneath the Earth's crust. Basalt is rich in iron and magnesium minerals and is commonly found in oceanic crust. It is created through the process of seafloor spreading at mid-ocean ridges.
If volcanoes get their magma from the crust below them what can you say about the silica content of Earths crust under the oceans?
The silica content of the Earth's crust beneath the oceans is typically lower compared to the crust beneath continents. This lower silica content results in a type of magma known as basalt, which is commonly associated with oceanic volcanoes like those found along mid-ocean ridges.
What type of crust is under the continents?
contianal crust
The rock that underlies the oceans is granite?
The rock that underlies the oceans is primarily basalt, not granite. Basalt is a volcanic rock that forms from solidified lava, and it makes up most of the oceanic crust. Granite, on the other hand, is a different type of rock that is more commonly found in continental crust.
Where is the thickest part of earth's crust found?
The thickest part of the Earth's crust is typically found beneath mountain ranges, where tectonic plates collide and push the crust upward, creating a thicker layer of rock. This thicker crust is known as continental crust and can be up to 70 km (43 miles) thick in places like the Himalayas.
Type of crust on which all continents are found?
Continental crust.
Which type of rock is most commonly found buried deep under mountains or in the Earth's crust?
igneous rocks
Is it true that tectonic plates made up of land and ocean floor?
Yes, there are two types of crust on the Earth, oceanic and continental. The crust under the oceans is, of course, oceanic crust which has more mass than continental crust. Each type is formed from plates of different size and shape.
What is continental and oceanic crust?
Continental crust is the thicker, less dense, and older type of crust found beneath continents, primarily composed of granite and sedimentary rock. Oceanic crust is the thinner, more dense, and younger type of crust located beneath oceans, primarily composed of basalt. The boundary between continental and oceanic crust is known as the continental-oceanic crust boundary.
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 type of soil found in the ocean?
The oceans do not have soils.
