The mantle is composed primarily of silicate minerals rich in magnesium and iron. It is approximately 2,900 kilometers thick and is located between the Earth's crust and the core.
If continental crust were thinner than its average thickness of 40km, it would depress the mantle less than it does now. This is because less mass in the thinner crust would exert less pressure on the mantle, resulting in less depression.
Continental crust is less dense than oceanic crust, so it floats higher on the mantle. This means that the same thickness of continental crust will displace less mantle compared to oceanic crust. Additionally, continental crust is composed of lighter rocks like granites, while oceanic crust is made of denser rocks like basalt.
The thickness of Earth's layers vary depending on the specific layer. For example, the Earth's crust can range from 5-70 km thick, the mantle is about 2,900 km thick, and the outer core is approximately 2,200 km thick. The inner core has a radius of about 1,220 km.
The crust is the outermost layer of the Earth, consisting of solid rock that varies in thickness from about 5 to 70 kilometers. The upper mantle lies beneath the crust and is more rigid, extending to a depth of about 660 kilometers. Both layers are part of the Earth's lithosphere.

Since the lithosphere includes both the crust and the uppermost part of the mantle, you can subtract the thickness of the crust (50 km) from the total thickness of the lithosphere (150 km) to find the thickness of the mantle. Therefore, the thickness of the mantle would be 100 km.
In oceanic areas the upper mantle is usually 5-200km thick and on continental areas it is 75-300km deep.
both of them together is 333 kilometers. you can search the Internet for how thick the crust is and subtract that from 333 to get the thickness of the mantle part.
The earths mantle is one of the four major layers, laying between the crust and the outer core. At 2885 kilometers, it is the thickest layer.
the thickness of each part is the mantle, the inner core, and inner core
The Earth's mantle is approximately 2,900 kilometers thick and is composed of solid rock that lies between the Earth's crust and core. It is mainly made up of silicate minerals and is responsible for convection currents that drive plate tectonics and other geological processes on the planet.
