How do scientists study the interior of the Earth?

Even though it’s right under our feet, the interior of our planet is mysterious. Scientists can’t study it directly because we can’t dig deep enough into the planet to reach the inside. The deepest oil wells are only 6 km deep (less than 4 miles).

Even the deepest research hole was only 12 km deep (about 7.5 miles). That’s not very much, considering the average thickness of the crust is about 40 km (almost 25 miles). The mantle extends down to 2900 km (1800 mi) and the center of the Earth’s core is over 6300 km deep (that’s almost 4000 miles away)!

Using special instruments called “seismometers,” scientists study how seismic waves travel through the Earth to learn about the Earth’s mantle and core. How does the Earth generate a magnetic field? This is one those questions that scientists are still trying to answer.

The Earth’s core is made of dense metals like iron and nickel. The very center of the core is solid, but the outer core is liquid metal. As the planet rotates between day ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
