There are two important things that we know about the mantle: 1) that it is made of solid rock 2) it is hot. Scientists know the structure of the mantle because of the heat flow, seismic waves and meteorites. Heat flows through the Earth in two ways: convection and conduction.

6 Fascinating Facts About the Earth's Mantle
State: Liquid Composition: iron, nickel, sulphur and oxygen This liquid layer of iron and nickel is 5,150km deep. The outer core flows around the centre of the Earth, and the movement of the metals creates our planet's magnetic field. Lower Mantle Temperature: 3,000°C State: solid Composition: iron, oxygen, silicon, magnesium and aluminium

A photograph of Earth taken by the crew of Apollo 17 in 1972. A processed version became widely known as The Blue Marble. [2] [3] Measurements of the force exerted by Earth's gravity can be used to calculate its mass. Astronomers can also calculate Earth's mass by observing the motion of orbiting satellites.

Introduction Three centuries ago, the English scientist Isaac Newton calculated, from his studies of planets and the force of gravity, that the average density of the Earth is twice that of surface rocks and therefore that the Earth's interior must be composed of much denser material.

The Earth is a planet and is roughly the shape of a sphere . There are three layers that make up the Earth's structure. The three layers, starting from the outside, are: the crust - the rocky.
Earth's Internal Structure Photograph by Roger Harris
Understanding Earth's Interior. Before you can learn about plate tectonics, you need to know something about the layers that are found inside Earth. These layers are divided by composition into core, mantle, and crust or by mechanical properties into lithosphere and asthenosphere. Scientists use information from earthquakes and computer.

To really understand Earth, you need to travel 6,400 kilometers (3,977 miles) beneath our feet. Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. Except for the crust, no one has ever explored these layers in person.
GEOMORPHOLOGY Internal structure of the earth
Below: This view drawn to scale demonstrates that the Earth's crust literally is only skin deep. Below right: A view not drawn to scale to show the Earth's three main layers (crust, mantle, and core) in more detail (see text). Below the crust is the mantle, a dense, hot layer of semi-solid rock approximately 2,900 km thick.

Detailed Layer Model of the Earth For a more intricate understanding of the Earth's structure, geologists divide the layers of the Earth a bit differently, based on their physical and chemical properties. 1. The Lithosphere The lithosphere, about 10 to 200 km thick, includes the uppermost mantle and the crust.

What is happening inside this 12,700 km diameter ball we call the Earth? Some of the Earth's internal architecture is an 'educated guess' (mainly from seismology), because the longest drill we have has only penetrated 12.26 km - and there's 6,300 km between us and the centre of the Earth.

Diagram-3. Discontinuities of earth Mantle. The mantle extends from the base of the crust at a depth of 2900km. It comprises about 80% of the earth's total volume. Mantle contain Iron, magnesium and calcium. Because of increasing temperature and pressure inside the earth, it is hotter and denser than the crust.

This diagram shows us how thin the crust is in relation to the rest of the Earth, along with relative sizes of the mantle and core. Interestingly, there are two cores noted (the inner and the outer). Notice also how the chemical composition of the Earth varies with depth; near the surface, the Earth is dominated by silicon and oxygen.
