Scientists determined that the Earth has layers through studying how seismic waves travel. These seismic waves differed depending on how thick the layer was.
The earth has a total of 6 main layers.
Its in layers because of the density of the compounds in the earth
it is a part of the EARTH layers.
it is a part of the EARTH layers.
it is a part of the EARTH layers.
how many layers does the earth have and name them
the layers of the earth is crust (oceanic and continental), mantle and core (outer and inner)
sedimenatary rock create layers in the surface of the earth and eruptions from volcanoes also make layers of the earth.
The Earth has three compositional layers and five structural layers. Both layers have iron, magnesium, aluminum and silica.
Crust, Mantle, and Core are the 3 layers in the earth.
how do we know about the earth's layers when we never drilled that far down?
