This combined layer is called the lithosphere, which includes the crust and the uppermost solid portion of the mantle. It varies in thickness beneath the oceans and continents, with the oceanic lithosphere being thinner and denser than the continental lithosphere. The lithosphere is divided into large plates that move and interact with each other, causing geological phenomena like earthquakes and volcanic eruptions.

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 the earths crust less than one percent of earths mass?
No, the Earth's crust makes up less than 1% of the Earth's mass. The crust is the thin, outermost layer of the Earth, while the majority of the Earth's mass is in the mantle and core.
Which layer makes up the majority of earths interior?
The mantle is the largest layer in the Earth's interior.
What does earths plates float on?
Earth's tectonic plates float on the semi-fluid layer of the mantle called the asthenosphere. These plates move and interact with each other due to the convective currents in the molten mantle beneath them.
How is crust different from mantle?
The crust is the outermost layer of the Earth, which is thin and solid. It is divided into continental crust (underneath land) and oceanic crust (underneath oceans). In contrast, the mantle is the layer beneath the crust and is primarily composed of solid rock that flows slowly over long periods of time.
What is the earths very top of the mantle combined?
The very top of Earth's mantle is known as the lithosphere. It is a rigid layer that consists of both the uppermost part of the mantle and the crust above it. The lithosphere is broken into tectonic plates that float on the semi-fluid asthenosphere beneath it.
What is the earths crust and the very top of the mantle combined?
The Earth's crust and the uppermost part of the mantle together form the lithosphere. The lithosphere is a rigid outer layer of the Earth that is divided into tectonic plates which float on the semi-fluid asthenosphere beneath them.
What part of the earth is the crust and the very top of the mantle?
The crust and the very top of the mantle make up the lithosphere, which is the outermost layer of the Earth. The lithosphere is divided into several tectonic plates that move and interact with each other at plate boundaries.
How is the mixture of cornstarch and water different from the Earths Mantle?
the earths mantle is very hot were cornstarch is not hot at all

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.

Which layer makes up the majority of earths interior?
The mantle is the largest layer in the Earth's interior.
Is the lithospere located in the crust?
The lithosphere includes the crust and the very top of the mantle. The lithosphere is cool and brittle.
What is the composition of the mantl?
The earths mantle is less dense and it's very hot.
