Earthquakes occur frequently. They create different types of waves that travel through the earth at a variety of speeds. Certain waves are also reflected and refracted by some materials. As a result it is possible to tell where boundaries are between two different types of materials. By knowing the speed the various waves travel through the various materials, it is also possible to know the density of various materials.
Geologists know the material ejected by volcanoes of various types.
The density in the center of the earth is the same as a mixture of iron and nickel.
Just above the center of the earth is heavy material, but is a guess!
You don't have to be a genius to know this but a: Psychologist, Quantum Physicist, Geologist, Astro Physicist, And Mycologists need require some knowledge of science.
I really really really really really really really do not know
scientists know the mass and the volume of earth how could this information help them make inferences about thr kind of matter that makes up the earth interior
he general public would not feel comfortable using hydroelectic power because, why should they waste all this money to make the machines for it? I would want that cause shouldn't the public reserve the earths energy? he Earths energy wont be lasting forever you know.
Scientist study earth because earth is the place that we envolved on and is the only planet in our solar system that is know to support life and is the fifth- largest planet in our universe.
id ont know
Because of the study of seismic waves from earthquakes
Seismology - echo patterns of sound waves traveling through the earth.
I am learning about this in my Science class, and when a geologist looks at an extrusion, they know it's an extrusion because it is Igneous rock, and an extrusion helps tell the reletive ages of the layers around it.

Your local jeweler would know, show them to him. Also if you know a geologist, he would know also.
A Geologist needs to know a lot about geometry.

what can i do know about animal rights and Abuse deegry
to make sure that they know the history of the earth so they can predict future
I really don't know Actually they get paied 2000,000 dollars.
the three ways in which we know about the interior of the earth are:volcanoesearthquake waves-under the earthdrilling
