When earthquakes occur, scientists measure them using seismographs. Earthquakes produce a number of different types of waves. Some run along the surface of the earth. Some travel through the earth. Those that travel through the earth travel at different speeds. It is possible to create similar waves in a lab and measure how those waves travel through different types of materials. Since earthquakes occur all over the world, it is possible to measure the waves from all angles. Thus, if a wave travels a small distance through the core, scientists can tell by differences in speed what it would be if it traveled through all mantle material. So with the difference in speeds in different types of waves, scientists can figure out what is in the earth's interior.

Geologists use direct evidence from learn abut earths interior?
by direct heat
Is this question true or false to study earths interior geologists often rely on indirect methods such as evidence from fossils?
no they use seismic waves
What are four instruments that geologists use to and how both of them work?
a map, compase, globe, computer, they use them together
Geologists obtain indirect evidence about earth's interior by?
Geologists obtain indirect evidence about the earth's interior by reactions to seismic waves. They also use rock samples and drilling samples.
Why do geologists use drill bits covered with small diamonds to drill into earths crust?
the diamonds are the strongest natural material on earth. these drills can drill through anything
What do geoligists use to map the earths interior?
bananas are eatin by the earths interior
What geologists use direct evidence to learn about earths interior?
Geologists use evidence from seismic waves to learn about earth's interior. Geologists record the seismic waves and study how they travel through earth. By Brianna.

Why do you think geologists use drills bits covered with small diamonds to drill earths crusts?
Because they have to get through the minerals and rocks in the earths crust.
Geologist use direct evidence from what to learn about earths interior?
Studying how seismic waves refract inside the earth and if they "cast shadows" indicating that some layers inside earth are opaque to some types of seismic waves. Seismic waves "illuminate" the interior of the earth like light waves illuminate a room, permitting what is there to be seen if you have the correct tools to observe them.
Why do geologists use topographic maps as base maps?
Because a topograpic map is a map that shows surface features, or topography of an area.
Why do you think that the work of geologists is important to our daily lives?
geologists affect our lives in the following ways. they monitor seismic activities within the earths interior and are able to warn us of impending earthquakes and impending shockwaves geologists monitor volcanoes and are able tom predict when the next eruption will occur and the expected magnitude geologists are also important in the process of drilling boreholes as they have crucial information on the type of soil found in different areas and they can offer crucial advice in the process of drilling bore holes geologists also moniter the earths magnetic fields and can use this fields to date rocks which can then tell us crucial movements of tectonic plates
What type of map would you use to find the location of coal at earths surface and why?
geoligical map
