Composition of the Earth

It may seem like the Globe is made up of one large solid rock, simply it'south really made up of a number of parts. Some of them constantly moving!

You can recollect of the World every bit being made upwardly of a number of layers, sort of similar an onion. These layers go more than and more dense the closer to the center of the earth you go. Meet the picture below to see the iv master layers of the earth: the crust, curtain, outer core, and inner cadre.

Chaff

The chaff is the thin outer later of the Globe where we live. Well, it looks sparse on the pic and it is thin relative to the other layers, but don't worry, we're non going to fall through past accident anytime soon. The chaff varies from around 5km thick (in the body of water floor) to around 70km thick (on land where we live chosen the continental crust). The continental crust is made up of rocks that consist primarily of silica and alumina called the "sial".

Mantle

The side by side layer of the Earth is chosen the mantle. The mantle is much thicker than the chaff at almost 3000km deep. Information technology's made up of slightly unlike silicate rocks with more than magnesium and fe.

Tectonic plates

The tectonic plates are a combination of the chaff and the outer mantle, also called the lithosphere. These plates motility very slowly, effectually a couple of inches a year. Where the plates touch each other is chosen a fault. When the plates move and the boundaries bump up against each other it tin cause an convulsion.

Outer Core

The Globe's outer cadre is made upwards of fe and nickel and is very hot (4400 to 5000+ degrees C). This is then hot that the iron and nickel metals are liquid! The outer core is very important to globe as information technology creates something called a magnetic field. The magnetic field the outer core creates goes manner out in to infinite and makes a protective bulwark effectually the earth that shields united states of america from the sun's dissentious solar wind.

Inner Core

The Earth's inner core is made up of iron and nickel, just like the outer core, nonetheless, the inner core is dissimilar. The inner cadre is and then deep within the earth that information technology's under immense pressure. So much pressure level that, fifty-fifty though it is so hot, it is solid. The inner core is the hottest function of the Earth, and, at over 5000 degrees C, is about every bit hot as the surface of the sunday.
