What else can I help you with?
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.
In earths crust What type of rock is found under the oceans?
Oceanic crust, new oceanic crust is produced by seafloor spreading.
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 type of rock underlies a karst landscape?
Limestone is the most common type of rock that underlies a karst landscape. It is a soluble rock that is easily dissolved by water, leading to the formation of features such as sinkholes, caves, and underground rivers.
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.
Which type of rock usually underlies a karst topography?
Limestone is the type of rock that usually underlies a karst topography. Limestone is soluble in water, allowing for the formation of sinkholes, caves, and other karst features through the process of erosion.
What type of crust is found under the the oceans?
approimately 2250 milon years go the earth continets were grouped nto one landmasswht was this landmass called
What type of rock usually underlies a karst landscape?
Limestone is the most common type of rock that underlies a karst landscape. This is because limestone is soluble in water, allowing for the formation of karst topography features such as sinkholes, caves, and underground drainage systems.
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.
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.
What is the other type of crust the continental crust and what?
Oceanic Crust
Oceans have what type of water?
Oceans have salt water.
