What does seismic?
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.

What does seismic mean?
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
What creates a seismic wave and how does it propagate through the Earth's layers?
Seismic waves are created by the sudden release of energy from earthquakes or explosions. These waves propagate through the Earth's layers by traveling in a curved path, reflecting and refracting as they encounter different densities and compositions of rock. The waves can travel through solid, liquid, and gaseous layers, with their speed and direction changing depending on the properties of the material they pass through.
Why do waves travel in curved paths through the earth?
Because as they travel through the earth, the density of the material through which they are travelling will vary. This causes the speed of the wave to change which in turn results in a process known as refraction where the waves direction of propagation changes. As the density of the material in the earth continually increases with depth due to the increasing overburden pressure, the speed of the seismic waves will continuousy change with depth leading to continuous small changes in propogation direction which leads to the formation of a curved propagation path. Geophysicists make use of this phenomenon to estimate the density and structure of the interior of the earth. For more information, please see the related links.
What is a seismic wave that travels through Earth Interior?
A body wave is a seismic wave that travels through Earths interior.
Which seismic body wave can penetrate the Earth's core?
P waves are seismic body waves that can penetrate the Earth's core. They are the fastest seismic waves and can travel through both solid and liquid materials, allowing them to pass through the Earth's core.
Wave that passes through earth?
Seismic Wave. :D
Earthquakes produce what that travel through earth?
Seismic waves
What is the name for energy that travels through the earth?
Seismic waves.
How was Earth's core discovered?
By studying how seismic waves travel through the Earth's interior.
Do seismic waves need a medium to travel through?
Seismic, or earthquake waves travel through the earth. They may travel through our crust, which is rocky, or through the more fluid parts, like the mantle, but the medium is the earth.
