The Earth’s Layers
There are four layers of the Earth. They are the crust, mantle, outer core, and the inner core.
Scientists study earthquakes to find out what the inside of the Earth looks like. Scientists use a
tool called a seismograph to study earthquakes.
The first outer most layer is the crust, it’s Earth’s thinnest layer. It’s made of solid rock. The
crust is deeper under continents than under oceans. This layer of earth is crucial because it’s
the place we inhabit!
The layer of rock below the crust is the mantle. High temperatures and a lot of pressure is
inside the mantle. The mantle is Earth’s thickest layer. It’s made of silicon, magnesium, iron and
oxygen.
The third layer of Earth is the outer core. The outer core is scalding hot, and it’s most likely
made of melted iron. This is the layer closest to the inner core.
The last layer of Earth is the inner core, and it’s the hottest layer. The inner core is a solid
sphere of material in the center of the earth.
Again Scientists (also known as seismologists) study earthquakes so they know what the inside
of the Earth is like. As I had said before the layers of the Earth are different and special in many
different ways.
