Earth Layers

A seismograph is used to study and measure this layer.

This layer is impacted the most by meteorites.

This is the only layer that is made entirely of liquid.

This is the layer where you find magma.

The movement of magma in this layer causes tectonic plates to shift, which causes earthquakes.

This layer is the coolest (least warm) layer.

The temperature here is anywhere from 2,800 degrees C to 3,200 degrees C.

This layer is made of liquid metals that spin, which creates Earth's magnetic field.

This layer is covered with silt, dirt, and water.

This layer is where tectonic plates are found.

Almost 2/3 of the Earth's mass is made up of this layer.

This layer is made up of solid rocks.

Convection currents in this layer cause movement in tectonic plates.

The thickness here is about 2,250 km.

Only 1% of Earth's entire mass is made up of this layer.

This layer is about 1,280 km thick.

You find this layer at the center of the Earth.

The temperature here is 4,000-9,000 degrees Celsius.

This layer is made mostly of solid iron.

This layer's temperature is about the same as the surface of the sun.

This layer is made of liquid iron and nickel.

The land at the bottom of the ocean belongs to this layer.

There is so much pressure here that liquid metals are compressed into a solid.

This is the thinnest layer.

Your trip from your home to this layer will be about 6,380 km.
