Through Seismology, or through studying earthquakes, we have been able to find that the Earth's interior is composed of three layers: Crust, Mantle and Core. The core is further divided into outer core and inner core.

Is it true when you study earth's interior geologists often rely on indirect such as evidence from fossils?
No. Fossils tell us about what was living at or near the earths surface in the past, they do not tell us about the Earth's interior. When studying the Earth's interior, geologists look at micro gravity variations (which tell us about density differences in deep rocks), magnetic variations (which tell us a bit about the deep rocks composition) and most importantly seismic records (which tell us about the physical properties of the deep rocks). We also look for deep rocks that have been brought to the surface during the collision of continents (the roots of mountains) and volcanic events (such as diamond pipes).
What method tells us about earths internal structure?
Seismic tomography is a method that tells us about Earth's internal structure. It uses seismic waves generated by earthquakes to create detailed images of the Earth's interior. By analyzing how these waves travel through the Earth's layers, scientists can infer information about the composition, density, and temperature of different regions within the Earth.
Why do scientists believe what they do about Earth's interior?
Scientists study about the Earth's interior for many reasons. Some include knowing how the inner layers of the Earth work and act allows us to better predict the effects and locations of earthquakes and volcanoes. They also study more about its magnetic field, and long-term continental drift.
Do tides occur in the molten interior of the earth for the same reason as ocean tides?
That sounds reasonable, but those tides don't affect us as much, so you don't hear much about them.
What do study Seismology?
A seismologist studies earthquakes and the propagation of earthquake waves (more correctly termed seismic waves) through the Earth and what these can tell us about the structure of the Earth (much like dolphins use sonar to see objects underwater).Earthquakes.Earthquakes and seismic activity.
What application does seismology have besides measuring the magnitude and located of earthquake?
Reflection and refraction seismology can be used in geophysical exploration to locate layers of varying density which can be used for example to locate underground hydrocarbons in the oil and gas industry. Seismology has also provided us with information on the internal structure and state of matter of the interior of the Earth. Please see the related links.
What do s shadows tell us about the interior of the earth?
it tells us that the earths interior (core) is a liquid
Is it true or false that Earthquakes permit us to see the structure of the Earth's interior?
It is true that seismic waves from earthquakes allow us to interpret the structure of Earth's interior.
What characteristic of the earth's interior is likely to be responsible for the earth's magnetic field?
what characteristic of earth's interior is likely to be responsible for earth's magnetic field
How does mining help us to understand the interior of the earth?
Mining helps us to understand the interiors of the earth because we can learn about how long the earth has been around and about different kinds of dirt.
When an earthquake occurs data from one seismograph can tell you what?
The waves of earthquakes help us determine information about the interior of the earth. The more geologists know about the interior of the earth, the better they can predict earthquakes and other changes in the formation of the Earth's crust.
What do volcanoes and earthquakes tell us about the structure of earth's interior?
I love earth! How bout you?That God has made thing for us to learn about and wonder, "why does this happen?"Also it shows us that our earth always go through changes.

When was Songs the Lord Taught Us created?
Songs the Lord Taught Us was created in 1980.
Why is the study of earthquakes so important?
It helps us to understand the changes taking place in the earth's crust and it helps us to corrolate the amount of damage done to the strength of the quake. It can also tell us some other important things such as if a volcano is becoming more or less active. It can tell us something about the size of a tsunami which could have been produced by the earthquake under water etc... so there are many reasons to understand and measure the strength of earthquakes. this is actually coped and pasted from another place
What theories are keeping us from going deeper into the Earth?
Because, the conditions going closer to the Earth is too hot for a human to handle. Also, there is too much pressure when you go lower to the Earth's interior. ~HOPE THIS HELPS :D
What is the name of the current US secriterry of interior?
Kenneth L. Salazar is the current US Secretary of the Interior
