What order do seismic waves come in?
First P waves, seismic waves that compress and expand the ground like an accordion. Then S waves, seismic waves that vibrate from side to side as well as up and down. And finally Surface waves, they move more slowly than P waves and S waves. But they can produce severe ground movements.
How do scientists use seismic waves to work out the structure of the rocks beneath the surface?
Scientists use seismic waves to determine the structure of rocks beneath the surface by studying how these waves travel through different rock layers. The speed and direction of seismic waves change as they encounter different rock densities and compositions, providing insight into the subsurface geology. By analyzing the patterns of seismic wave propagation, scientists can create detailed images of underground rock formations.
A difference between sound waves and seismic waves?
Sound waves are longitudinal waves that travel through mediums such as air, while seismic waves are a combination of both longitudinal (P-waves) and transverse (S-waves) waves that travel through the Earth’s interior. Seismic waves are typically caused by geological events like earthquakes, while sound waves are produced by vibrating sources like speakers or instruments.
Can Seismic waves travel through space?
NO! Seismic waves can't travel through space. They are mechanical waves. Mechanical waves require going through mediums and there isn't a medium in space.
What do earthquakes waves transmit?
Seismic waves (like all waves) transmit energy.
The part of the Earth that stops or slows down seismic waves?
The outer core is the part of the Earth that slows down or stops seismic waves due to the change in density and composition from the mantle. Seismic waves travel faster through solid materials like the mantle and crust, but slow down when they reach the liquid outer core.
What kind of movements is produced by each of the three types of seismic waves?
P waves - compress and expand the ground like a Accordion S waves - vibrate from side to side as well as up and down Surface waves - make the ground roll like ocean waves The Earthquake is produced by each of the three types of seismic waves.

Which seismic waves travel the fastest?
Primary waves (P-waves) are the fastest seismic waves and are the first to be detected after an earthquake. They are able to travel through solid rock, liquid, and gas, making them the fastest seismic waves.
Can there be a seismic wave without having an earthquake?
It is possible to have a seismic wave without having an earthquake. Any wave moving through the ground is a seismic wave, and all earthquakes are seismic waves. But seismic waves can be created by volcanic action, landslides, meteor strikes or the like. Though all earthquakes are seismic waves, not all seismic waves are earthquakes.

What type of seismic wave can make the ground roll like ocean waves?
Surface waves can cause the ground to roll like ocean waves. Surface waves are a type of seismic wave that travel along the Earth's surface and have a more pronounced effect on buildings and structures compared to other types of seismic waves.

The type of seismic waves that arrive at the surface first and move by compressing and expanding the ground like an accordion are called?
The type of seismic waves that arrive at the surface first and move by compressing and expanding the ground like an accordion are called primary (P-waves) or compressional waves. They are the fastest seismic waves and can travel through solids, liquids, and gases.
Can Seismic waves travel through space?
NO! Seismic waves can't travel through space. They are mechanical waves. Mechanical waves require going through mediums and there isn't a medium in space.
Do seismic waves weaken or strengthen as they move away from the focus point?
Seismic waves weaken as they move away from the focus point due to energy loss as they travel through the Earth's layers. The farther the distance from the focus point, the weaker the seismic waves become.
