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.
What else can I help you with?
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 obtained by studying earths interior?
The earth's interior is called the core.
What is the center of the earths interior made of mostly of iron?
core
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..............
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.

How do scientists observe the earth interior?
Scientists observe the Earth's interior using seismic waves generated by earthquakes or man-made explosions. By studying how these waves are transmitted and reflected within the Earth, scientists can create models of the Earth's interior structure, including the different layers such as the crust, mantle, and core. Other methods, such as gravity measurements, magnetic field studies, and laboratory experiments, also contribute to our understanding of the Earth's interior.
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
How does Scientists divide earths interior into the crust mantle and core based on?
Scientists divide Earth's interior into the crust, mantle, and core based on their composition and physical properties. The crust is the outermost layer and is made of solid rock, the mantle is predominantly solid but can flow slowly over geological timescales, and the core is mostly metallic and divided into a liquid outer core and a solid inner core based on their differing states of matter.
What made the Earths layers?
Your mom made the earths layers
How is the speed of earthquake waves used to provide information about earths interior?
Primary Waves or P waves come first and they are the quickest and travel through earth's interior. So if there is an earthquake in China the P wave will go through the earth and onto the other side in a couple of seconds and scientists know this because only a p wave can travel through liquid, solid, and gas and the interior of the earth is made up of semi-molten rock, molten rock and solid rock so we kind or know how the earth is inside.
What made Julius Caesar impopular?
figured it out
