What are seismic waves and what information information do they give about earthquakes?
Earthquakes are when the seismic plates on the earths crust move after pressure from on another is exceeded, seismic waves are produced after an earthquake, and can turn into a tsunami.
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.
How do geologists use seismic waves to learn about earths?
Seismic waves are used indirectly I have a question for you is this from a chapter 9 science packet section one because I have the same.
Why do seismic waves speed up beneath the surface of continents?
Because earths crust is denser than the mantle
What contributes the lack of evidence of the period of heavy bombardment on earth?
Earths valcanoes
How do you obtain indirect evidence about earths interior?
Seismic waves
In developing a model of earths deep interior most of the evidence was determined from?
Seismic data
How do fossils provide evidence for moving plates?
Their evidence comes from rocks at earths surface.
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
What evidence do scientists have to support the relationships of the earths parts?
a. seismic waves b. volcanoes c. earthquakes d. rocks
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.
Geologists learn about Earths interior using indirect evidence from?
Geologists learn about Earth's interior using indirect evidence from seismic waves, magnetic field data, and rock samples from volcanoes and deep drilling. These methods help provide insights into the composition, structure, and properties of Earth's interior layers.
Geologist use direct from what 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.
If holes drilled sveral kilometers into earths crust provide direct evidence about earths interior in the form of what?
Rock samples
Holes drilled several kilometers into the earths crust provide direct evidence about earths interiors in the form of?
Rock Samples.
What is the seismic wave that travel's through the earths interior?
A body wave is a seismic wave that travels through Earths interior.
What two types of rock provide evidence of the composition of earths interior?
What two types of rock provided evidence of the composition of Earth'sinterior
