How to describe one way in which geologists have gained indirect evidence 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 might an earthquake's primary wave but not it's secondary wave reach a location on the other side of the world from the epicenter?
Only primary waves travel thought the earths interior because S waves cannot travel through the liquid portion of Earths interior and P waves can. Whoever you are, you were just schooled by an eighth grader =)
Where in the interior of earth do geologists believe that the earths magnetism is influenced?
Convection of liquid metals in the outer core creates the Earth's magnetic field.
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.
What keeps the earths core so hot?
light and heat(i heard some1 say radiation 1ce but i dont think its true)
How do you obtain indirect evidence about earths interior?
Seismic waves
What does most of your knowledge about Earths interior crust come from?
The study of volcanoes,
Geologists learn about Earths interior using indirect evidence from?
Geologists have used two main types of evidence to learn about Earth's interior: direct evidence from rock samples and indirect evidence from siesmic waves.
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
Is earths interior hot or cold?
The earths interior is cold
Why do you think scientists study earths interior?
why do you think scientists study earths interior?if you were a scientists ,will you undertake a study of the earths interior?
What two types of evidence geologist use to learn about earths interior?
Rock samples and Indirect evidence from seismic waves Direct evidence from rocks samples and indirect samples from seismic waves my science teacher told me
Does indirect evidence of earths interior come from studying rock samples?
Geolagists think yes but everyone says NO what do u think? Love morganc😜
What do geoligists use to map the earths interior?
bananas are eatin by the earths interior
What is the seismic wave that travel's through the earths interior?
A body wave is a seismic wave that travels through Earths interior.
How does temperature of earths crust compare to the temperature of earths interior?
it depends on the deepth
How the earths interior is divided into layers?
crust
