The distinction between the crust and mantle is primarily on the basis of a difference in?

composition — the crust is primarily composed of lighter, silicate minerals like granite and basalt, while the mantle is composed of denser minerals like peridotite. This compositional difference contributes to variations in density, temperature, and behaviour between the crust and mantle layers of the Earth.


What is the difference between between the lower and upper mantle?

The upper mantle is harder than the lower mantle


What is the difference between the mantle and a convergent plate boundary?

The mantle is below the plates.


What is the Difference between mantle and appendage?

Compare molting and metamorphos


Give two differences between the mantle and the core?

The mantle is a layer of the Earth that lies between the core and the crust, while the core is the innermost layer made up of the outer liquid core and the solid inner core. Another difference is that the mantle is mainly composed of solid rock materials, while the core is primarily made up of metallic elements such as iron and nickel.


What is the difference between Mohorovicic discontinuity and Gutenberg discontinuity?

The Mohorovicic discontinuity, or Moho, is the boundary between the Earth's crust and mantle, marking a change in seismic wave velocity. The Gutenberg discontinuity is the boundary between the Earth's mantle and outer core, where seismic waves change velocity and nature. Essentially, the Moho separates the crust and mantle, while the Gutenberg discontinuity separates the mantle and outer core.


What is the composition and approximate thickness of the mantle?

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.


Is primarily made up of igneous rocks.?

mantle


What is the difference between the Mohorovicic discontinuity and the Gutenberg discontinuity?

The Mohorovicic discontinuity (Moho) is the boundary between the Earth's crust and mantle, where seismic waves change velocity. The Gutenberg discontinuity is the boundary between the Earth's mantle and outer core, characterized by a sharp increase in seismic wave velocities.


What is the composition of the mantl?

The earths mantle is less dense and it's very hot.


Where you the earths mantle located?

The Earth's mantle is located between the outer core and the Earth's crust. It is a layer of hot, dense rock that is primarily composed of silicate minerals. The mantle makes up the bulk of the Earth's interior and plays a key role in plate tectonics and the movement of the Earth's crust.


What divides the mantle and the core?

The boundary separating the Earth's mantle and core is known as the core-mantle boundary. This boundary is characterized by a sharp decrease in seismic wave velocities, indicating a difference in composition and properties between the outer core and the lower mantle.
