Stuff about the Inside of the Earth
Below are stuff about the inside of the earth. In plate tectonics, it is important to study
stuff about the inside of the earth. Understanding what are underneath the surface of the earth is key to
understanding plate tectonics.
Although people have not been deep inside the earth and survive to tell us stuff that go on
inside the earth, earth scientists have managed to study quite extensively about the inside of the earth. Their
work have helped explain earthquakes and volcanoes.
See the diagrams of inside the earth so that you
can understand the texts below about the inside of the earth better.
Just like an egg, the earth has a crust on the outside. The earth's crust is the skin of the
earth. The earth's crust is the hard surface on which we live on. The crust is not uniformly thick all over the
surface of the earth. Some parts of the earths crust are thicker than others. Some parts of the crusts are the
oceans which are deep, some deeper than others.
In the past, people thought the crust was a solid plate or rock sheet but with the discoveries
of plate tectonics, now we know that the crust is made up of large separate plates called the tectonic plates,
whose name plate tectonics was derived from.
Mantle and Magna
The mantle of the earth is just beneath the earth's crust. The mantle is very hot and is
liquidly. The mantle composes of melted rock called magma.
The Core of the Earth
The core of the earth is solid metal or primarily iron and nickel. The core of the earth is
surrounded by hot liquid metals.
