How have scientists figured out what the earths interior is made of?

Since we're not (yet?) able to drill a hole down there and find out, we're reduced to indirect measurements. Things like the mass of our planet and its gravity. (That's why we're pretty sure that the core is primarily iron.) The speed of earthquake vibrations in the mantle. The material that comes out of the Earth in volcanoes. Stuff like that.

Geologists have learned that earths interior is made up of layers or trenches?
Layers.
What are these parts primarily made up of in the earths interior?
they are crust and the mantle and also the core
Which part of earths interior is made mostly of nickel and iron and has liquid and solid parts?
The core..............
What have scientists observed in order to learn about earth's interior?
The Earth's size and overall density The Earths Geological features The Earths magnetic field The variations in observed gravity and magnetic fields as compared to the a theoretical model of what these should be. The variations in speed of and type of seismic waves as they propagate through the earth after a man made explosion or earthquake. Meteoric material that has fallen to earth.
What does the existence of geysers and volcanoes provide scientists about earths interior?
Geysersspout up 70 feet.With a terrible hissing noise,at regular intervals. In this section are the great springs ,so hot that meat is readily cooked in them.
What is the center of the earths interior made of mostly of iron?
core

Did Sara Palin speak with scientists to conclude that global warming is not man made?
I'm sure she figured it out by herself.
What element makes up of the earths core?
scientists think that the earths core is made up of mostly iron, and contains smaller amounts of copper nickel.
Which of these extraterrestrial bodies do scientists think brought water to Earths surface?
Comets, because they are made from ice and dirt.
What element makes up most of the earths core?

Why do scientists think earths core is made of iron?
Apex anwser Iron is a heavy element and would sink into the planet.
What information does the existence of geysers and volcanes provide scientists about Earth's interior?
Because you can figure out when it will erupt and to learn what lava is made out of
What made the Earths layers?
Your mom made the earths layers
