What else can I help you with?
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 =)
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.
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 is much of earths usable freshwater obtained from?
The largest source of freshwater on earth is ice sheets, glaciers, and icebergs. The Great Lakes are the largest fresh water on the planet.
What prevents geologists from studying earths interior?
Depth, temperature and pressure barrier.
What do geoligists use to map the earths interior?
Geologists use seismic waves to map the Earth's interior. By studying how these waves travel through the Earth, geologists can infer information about the composition and structure of different layers beneath the surface. This helps them understand the different layers of the Earth, such as the crust, mantle, and core.
Is earths interior hot or cold?
The earths interior is cold
Why do you think scientists study earths interior?
Scientists study Earth's interior to better understand the planet's composition, structure, and dynamics. This helps in predicting natural disasters like earthquakes and volcanic eruptions, as well as in understanding processes like plate tectonics and magnetic field generation. Studying the Earth's interior also provides insights into the planet's history and evolution.
What do s shadows tell us about the interior of the earth?
Shadows can provide information about the depth and direction of geological features, such as mountain ranges or volcanic peaks, on the surface of the Earth. By studying the lengths and angles of shadows, geologists can infer the approximate shape and elevation of land formations, helping to better understand the Earth's interior composition and structure.
Which have scientist learned from studying seismic waves that travel through earths interior?
The speed of the waves that travel through the interior can tell the density of each layer of the Earth. Some waves can make it through certain layers, but not others.
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
Is powered by energy from the earths interior?
Volcanoes
Which is powered by engery from earths interior?
Volcanoes
Which type were useful to seismologists in their study of earths interior?
Seismic waves such as P-waves and S-waves have been crucial for seismologists in studying the Earth's interior. These waves travel through the Earth at different speeds and can provide information about the composition, density, and structure of the Earth's layers. By analyzing how seismic waves behave as they pass through the Earth, seismologists can gain insights into its internal properties.
What happens in earths interior to produce earths magnetic?
The movements in the liquid inner core.
