How do geologists use seismic waves to learn about the Earth interior?
because the waves travel through the solid crust and simisolid mantle they help see where the epicenter from an earthquake is
What direction do seismic waves move?
S waves shear rock back and forth as they travel through it.
Does a tsunami travel radially outward from its epicenter?
correct!
Which forms of matter can primary and secondary seismic waves travel through?
Primary seismic waves are longitudinal waves. Longitudinal waves can travel through solids, liquids and gasses (although seismic waves are of to low a frequency to normally be heard). Secondary seismic waves are transverse waves and only travel through solids.
What is a seismic monitor?
A machine or program to measure seismic waves that travel through the earth after an earthquake or explosion.
What happens to seismic waves as they travel out from the epicenter?
They get weaker as they travel out from the epicentre
In what diection does a seismic wave travel?
Seismic waves travel in all directins radiating out from the Earthquake's epicenter and/or focus.
What is a seismic travel time curve?
A seismic travel time curve describes the relation between the travel time of a seismic wave and the epicentral distance. It is used to calculate the calculate the distance of the earthquake's epicenter from the seismograph.
A travel-time graph can be used to find the?
The distance of an earthquake epicenter from a seismic station. Using the Three point method, the distance from 3 seismic stations are used to locate the epicenter by triangulation.

What is is a seismic travel-time curve and how is it used to study earthquakes?
i only know that it is used to measure the distnace from the epicenter

Why is three the minimum of the stations necessary to locate an epicenter?
A single seismic station can tell you the distance to an earthquakes epicentre but will give you no information on it's location. Seismic vibrations take time to travel to a seismic station and when you have two seismic stations you can narrow down the location of the earthquake's epicentre to two possible locations. Add in a reading from a third station and you can nail down the exact location because if you draw 3 circles one round each station with the size of each circle proportional to the distance of the station form the epicenter, they will intersect at one location on the planet and that location is the epicenter.
Why is three the minimum number of stations necessary to locate an epicenter?
Three seismic stations are needed to find the epicenter of an earthquake because all three radial circles made by the stations will only meet at one point. (example: if you only had to circles they would meet at two different points)At least 3
What direction do seismic waves move?
S waves shear rock back and forth as they travel through it.
What are seismic waves that reach the earths surface and travel outward?
the one with the most damege is the surface wave because they are on the surface of earth. but p-waves are the second and s-waves are the third
What does seismic?
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
