Explain the way that different seismic waves affect rock as they travel through it?
P waves: the rock spring back to its original shape S waves: the rock is deformed from side to side Surface waves: the rock goes up and down
What may be the main cause of the plates to move?
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move.
L waves in an earthquake?
The L wave, or Love wave (named after British geophysicist A. E. H. Love), causes rock to move horizontally, or side to side at right angles to the direction of the traveling wave, with no vertical displacements. L waves are surface waves that cause damage as they shake the ground underneath the foundations of buildings and other structures. This is a piece of junk.
How does the earth's surface move?
the earth's surface is known to move because of the shifting and sliding of thick sections of rock called plates, which is where the earth's crust sits on. This movement can cause magma, gas, and ash to shoot up and cause a volcano, and also cause an earthquake when the plates shift and slide.
How do P-waves differ from S-waves?
First of all, P stands for primary and S stands for secondary. P waves move in a compressional motion, similar to a slinky. S waves move in a shear motion perpendicular to the direction the wave is travelling.
How do surface waves move rock particle?

What happens to S waves when they reach the liquid part of the Earth's surface?
S waves cause rocks particles to move from side to side. The rock particles move at the right angles to the direction of the waves. However liquids can not support shear stresses and therefore S waves can not propagate through them.
What kinds of waves cause particles in rock to move at right angle to the direction of the wave?
secondary waves
Which travels faster P waves or S waves?
p waves because they move rock back and forth which squeezes and strecthes the rock as they travel through the rock. s waves shear rock side to side as they travel through the rock
What are waves of energy released by movements of rock under the earth's surface?
These are known as seismic waves.

What are the fastest type of waves and causes rock to move back and forth?
p-waves

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 the seismic waves of the Earth's crust?
Rock under stress breaks at the focus, releasing energy and vibrations called seismic waves, which travel away from the focus, through Earth's interior, and across the surface. The three types of seismic waves are: Primary waves: The first to arrive at seismographs Secondary waves: The second to arrive at seismographs Surface waves: The last and most severe to arrive at seismographs
