Layers of Earth
The Earth is not just a solid ball of rock it has four layers. The four
layers are crust, mantle, outer core, and the inner core. Scientists use
seismographs after earthquakes to learn about Earth’s layers. This helps
them see how the layers form the earthquakes.
We live on the crust of the Earth it has grass and minerals. The
crust is Earth’s outermost layer of Earth. Earth’s thinnest layer is the
crust on top of all the other layers. The crust is mostly made up of solid
rock so it is hard to break in some places. The crust is deeper under
continents than under oceans.
The mantle is the thickest layer out of all the other layers. The
mantle is the layer of rock lying below the crust. The mantle’s rock move
or flow due to pressure and high temperatures.
The outer core is totally liquid and the second to last layer. The
outer core is also made up of melted iron. The inner core floats right
inside of the outer core.
The inner core is a solid sphere. The inner core is located at the
center of Earth.
There are many more facts about Earth and more interesting
facts. Earth has a lot more features than just that.
