Let's take a look at each of them individually. The mantle is much thicker than the crust, and measures some 2,900 km in depth and is mainly composed of silicate rock such as olivine, garnet, and pyroxene; or the rock known as magnesium oxide. Read on to find the answers. The mantle is the layer of the earth that lies below the crust and is by far the largest … These layers get more and more … As the Earth rotates, the outer core (consisting of iron) spins over the inner core and generates the Earth’s magnetic field. The earth is made up of several layers and each has unique properties, characteristics, composition and affects the inner processes of the earth differently. As mentioned, the tectonic plates which form the mantle, are often described as ‘floating’ in the mantle. Earth Is Like a Hard-Boiled Egg! Composition: iron, nickel, sulphur and … The Crust. Mantle – Mostly solid rock but parts are hotter and more fluid The four main layers of the Earth are the crust, mantle, outer core, and the inner core. This free Earth layers activity is perfect for every primary school pupil. The outer core is liquid and made up of iron and nickel. These layers get more and more dense the closer to the center of the earth you get. The other type of crust is known as  the oceanic crust, is considerably thinner, denser, and made up of rock basalt. At the very centre of the Earth is what is known as the Inner Core. This is anything below sea level, and the thinner layers hold the oceans, seas and gulfs. Within the mantle, there is a range of temperature, which rises depending on depth. The earth is split into four major layers: the crust, the mantle, the outer core and the inner core, The crust is what humans live on, and it consists of only one percent of the Earth's mass, The centre of the Earth is a solid ball of nickel and iron roughly 70% the size of the moon.
