The mantle is the thickest layer of Earth, making up about 84% of the planet’s volume. It extends from the bottom of the crust to a depth of about 2,900 km. It is composed of silicate rocks rich in iron and magnesium. The mantle is semi-fluid and contains convection currents that ...

he Earth's structure is made up of several layers. The crust is the outermost layer on which we live. Right beneath 1 the mantle (地幔), a warm, semi-liquid layer of rock. This is 2 by a thin shell of liquid iron that forms the outer core. 3 , there is a solid inner core, ...
Many different layers (层) of rocks form the earth's crust (地壳). The layers of rocks are not flat (平坦的) and even (均匀的) like walls. Because of the great weight on them, these layers could fold (折叠) downward at weak places, and this finally leads to a break in the crust...
The Earth is composed of several layers: the crust, a thin outer layer; the mantle, a thick semi-solid layer beneath the crust; the outer core, a liquid layer of iron and nickel; and the inner core, a solid iron-nickel center. Each layer varies in compos

crust. The crust is divided into sections which are called plates. When two plates push against each other,or when two plates rub against each other,an earthquake happens. An earthquake causes the ground above the plate to shake. The shaking is caused by the movement of the plates. Earthqu...
