Why is earths core more dense than earths mantle?

Because the gravity is pushing the core together more so its more dense.

Is earths mantle 3000 kilometers thick?

The mantle is one of the three main layers of the Earth. It lies between the core and the crust. The mantle consists of hot, dense, semisolid rock and is about 3000 kilometers thick.

How many layers in earths mantle?

there are 7 layers in earths mantle.

Why do convection currents happen in the mantle?

Convection Currents occur when the heat from the earths core rises and heats up the mantle. the particles then become less dense and rise but when reaching the surface or top they cool back down, become more dense and heavy therefore dropping

How deep is earth's mantle?

The middle part of the earths three layers is the mantle. mantle starts from 5 to 70 km underground depending on the type of land. It consists of dense and hot silicate rocks that are about 2900 km or 1802 miles thick.

What are the three parts that make up Earths mantle?

How much degrees is the upper mantle?

The upper mantle is a hot area of earths interior that is less dense than the lower mantle. It goes from 250 kilometers to 600 kilometers or150 miles to 400 miles. Its composition is Silicon Oxygen Iron and Magnesium. It is a liquid.

Is the mantle dense?

The mantle is more dense than the asthenosphere, lithosphere, and the crust. The inner core and the outer core are more dense, however. The mantle is also a solid. I am learning this in my science class right now! :)

How does plate tectonics affect the mantle?

Tectonic Plates float on top of the earths mantle, the earths mantle is made up liquid which is always circulating.

Is the Earth's crust more dense than the core and the mantle?

No, both the core and mantle are more dense than the crust. The crust is the least dense layer.

What is the earths crust and upper part of the mantle called?

The Earths crust and upper part of the mantle is called the Lithosphere

What element is not found in large quantities in Earths mantle?

The element carbon is not found in large quantities in Earths mantle.

Is the crust more dense then the mantle?

No the mantle is denser than the crust.

Why do the earths continents float on the liquids mantle of the earth?

The continents "float" on the liquid mantle of the Earth because the metals that make up the mantle are very dense. The continents move when magma is pushed through the crust of the Earth in places like the Mid-Atlantic Ridge. The continents "float" on the liquid mantle of the Earth because the metals that make up the mantle are very dense. The continents move when magma is pushed through the crust of the Earth in…

What is the average density of the earths mantle?

4152 kg/m3 The earths mantle has a density of about 3.3 g/cubic cm.

How dense is the mantle?

To tell you the truth I only know that the mantle is less dense than the inner core. It is not as low dense as the crust or the outer core but it is basiclly the second most dense out of them. Do you get it kind of what I'm saying?

What is the difference between the earths mantle and core?

The difference between the earths mantle and the core is that the mantle is liquid metal while the core is solid. However both are very hot.

How far is the mantle away from the crust of the earth?
