the earth is in solid and liquid form thus penetration is different tha:t account for the different earth layers.
Layers I believe.
Scientists use seismic waves to map Earth's interior by using seismographs that measure the times at which seismic waves arrive at different distances from an earthquake.
Scientists use the difference in density between the inner and outer core as evidence that the inner core is solid. This was proven using seismic waves traveling through the earth.
The awnser is atmosphere. It surrounds the earth protecting the life on earth. Thank you for using this Awner.
by using the dynamite or other energy sources which produce vibration in the earth, we can produce seismic waves. answered by geologist M Tariq Niaz AJK University Muzaffarabad, Pakistan

- By using seismic waves .
I'm not sure but I hope someone Smart can answer it
layers
Scientists use seismic waves to map Earth's interior by using seismographs that measure the times at which seismic waves arrive at different distances from an earthquake.
Severals methods are all combined to give the scientist info on the layers of the Earth. For example they study the influence of the earth on orbits of the moon and other planets (mass distribution of the earth, mass density). They study the way seismic waves go through the earth which gives knowledge of layers. They use wave to sound. They examine sample of earth.
It's because of the different levels of carbon or something.

Using data from seismic waves geologists have learned that Earth's interior is made.
The cake had seven different layers.
Scientist learn about the earth's interior by studying seismic waves. 'P' waves travel all the way through Earth's crust, mantle, outer and inner core and give scientists a glimpse of the interior.
1. By studying things from Earths layers that have been pushed up through the cracks of the crust. 2.By measuring diffrent kinds of vibration from earthquakes 3.By doing laboratory expirements I hope this can help you!!
