How is it that so much is known about the interior of the Earth yet scientists have only dug as deep as about 10 km down?

Scientists aren't able to dig any deeper because the the temperatures, and there's a risk of digging into the mantle, which could be very dangerous. Scientists aren't able to dig any deeper because the the temperatures, and there's a risk of digging into the mantle, which could be very dangerous.

What can be used to map the deep interior of the earth?
The deep interior of the Earth can be mapped using seismic waves. Natural earthquakes produce seismic signals which penetrate the Earth. Timing the arrival of these waves at various sites round the world, gives indication of the shape and the wave velocity in the Earths interior. Rather similar to the way a CAT scan can reveal the interior of a person.
How do geologists study the earth's interior?
Knowledge of the Earth's interior is based on the reactions of seismic waves from earthquakes to the density and state of materials that they encounter. Rock that is torn off and expelled by volcanism is studied as another indicator of what lies below the surface. Another clue lies in meteorites that have landed on Earth known as Chondrites. These can indicate the material from which planets are formed. The study of Earth's magnetic field and gravitational properties also indicate or strongly infer what lies deep in Earth's interior.
How do scientists find out information on the core?
Scientists find out information on the core by using special tools to dig out samples from deep inside the earth. Special instruments "look inside" parts of the earth we cannot see.
What is the meaning of crust?
The crust is the top part of the Earth. It is where we live. The Earth's crust is 6 miles deep. That is the Earth's crust.
If the earth were a perfect sphere how deep would the water be that covered it?

Why is it difficult for scientists to know what the inside of the earth is like?
We can't actually visit the deep interior of the Earth, because the temperature and pressure would collapse any tunnel we dig or tube that we might insert.
How have scientists learned about the interior layers of the earth?
Scientists learn about the layers deep within the Earth's crust by studying how seismic waves travel through the Earth. ... By looking at the time of arrival of the main set of waves, and how the frequencies of the waves are arranged within the set, scientists can learn about the density and other properties of the layers.
Why is the deep interior of Earth unsuitable for people?
Because of the Earth's intense amount of pressure and heat
Why have scientists never dug a hole to the centre of earth?
Too deep
What is the energy source in vent ecosystems deep in the oceans?
Heat from Earth's interior.

What did scientists learn about earths interior by studying rock samples?
They can learn about conditions deep inside Earth, where these rocks formed. In addition, forces inside Earth sometimes blast rock to the surface from depths of more than 100 kilometers. These rocks provide clues about the interior.
Why do volcanoes get hot?
Volcanoes bring up material from deep within the earth. earth's interior is very hot.
What is endogenic?
endogenic forces have their origin deep down in the earth's interior and they work from below
What process deep within Earth do scientists suggest causes plate movements on Earth's surface?
continental drift
Who determined that S waves were unable to survive deep passage through the Earth's interior?
I donno. Your mom?
