How do scientists use seismic waves to work out the structure of the rocks beneath the surface?

The speed of the movement of the wave through the crust helps to work out the structure of the rocks below the surface of the earth. If the waves move slower the indication is that they are moving through a sedimentary type of rock such as sandstone. If the waves are moving more quickly that would indicate a more crystalline rock like granite..

What are seismic plates?
seismic plates, or tectonic plates, are huge 'plates' of rocks that exist beneath the earth's surface that rest upon molten rock. It is on the borders of these plates that 'fault lines' occur and these are hotspots of volcanic and seismic activity such as earthquakes.
What are the principles of seismic stratigraphy?
Seismic stratigraphy is a geologic approach to the interpretation of seismic data, allowing their application based on physical stratigraphy. Primary seismic reflections parallel the surface and nonconforming surface of the strata.
What is seismic tomography?
Seismic imaging is when seismograms take recordings of the Earth's surface. That are mapped into representations of its interior properties. Seismic imaging investigates the physical characteristics that lie underneath the Earth's surface.
Does the surface wave magnitude or M's measure the movement of seismic waves underneath the Earth's surface?
No, P-waves and S-waves are used to measure seismic events under the Earth's surface.
What is the molten rock found beneath the surface of the earth?
Molten rock beneath the earth's surface is called magma.
Why do seismic waves speed up beneath the surface of continents?
Because earths crust is denser than the mantle
What are the three seismic waves in order?
The three types of seismic waves are: P waves S waves Surface waves ( two surface waves. Riley surface wave and love surface wave named after scientists

What type of is Structure lying beneath the hard enamel surface of the tooth is?
Dentine
How can seismic waves be used to help scientists know what type of material each layer of earth is made of?
Seismic Tomography is the most popular technique used to find the Earth's sub-surface characteristics.
What do you call a coral structure that lies just beneath the surface of the ocean?
An Atoll A Reef A Bommy (Australian slang).
When was Beneath the Surface created?
Beneath the Surface was created in 1998.

Which seismic wave causes damage to da surface?
The surface wave.
What do seismic waves consist of?
Surface Waves
How scientists study the layers of the earth?
Scientists use their eyes where the layers have risen above ground and drill core samples to bring to the surface to study. Scientists use GPS tracking to study plate tectonics. by studying how seismic waves refract as they pass through different material.
