What area do seismic waves change in speed?

Mohorovicic Discontinuity. A+Good luck! ~K


Where is the place within the earth where the speed of seismic waves increases sharply?

The place within the Earth where the speed of seismic waves increases sharply is known as the Moho discontinuity, or Mohorovicic discontinuity. This boundary separates the Earth's crust from the underlying mantle, and seismic waves are thought to speed up due to the change in composition and density between these two layers.


What affects the speed of seismic waves?

The speed of seismic waves are affected by the type of material that the waves are traveling through. in other words (as an example): some type of waves can travel through rocks but not through liquids.


What are the type of waves that travel at a different speed through different materials?

These are called transverse waves. As they travel through different materials, their speed can change based on the properties of the material, such as its density or elasticity. Examples include light waves and seismic waves.


In which area do seismic waves change dramatically in speed?

they use vaginas


What happens to seismic waves in the air?

In air, the seismic waves(P-wave) are simply sound waves, and travel with the speed of sound (approx. 335 m/s).


How can seismic wave be used to infer the presence of the Mohorovicic Discontinuity?

Seismic waves change speed and direction when they encounter changes in the density and composition of rocks. The Mohorovicic Discontinuity marks the boundary between the Earth's crust and mantle, causing seismic waves to abruptly change behavior when passing through it. By analyzing the way seismic waves interact with this boundary, scientists can infer the presence and properties of the Mohorovicic Discontinuity.


What is ther kind of seismic wave that travels fast and increase its speed with depth?

The seismic wave that travels fast and increases its speed with depth is called a primary or P-wave. P-waves are compressional waves that can travel through solids, liquids, and gases, and they are the fastest seismic waves.


What causes seismic waves to change speeds as they move through earths layers?

Seismic waves change speeds as they move through Earth's layers due to differences in the physical properties of the materials in each layer. Factors such as density, rigidity, and composition of the rock can affect how fast seismic waves travel through them. The waves can speed up, slow down, or change direction as they encounter different materials with varying properties.


Do seismic waves speed up or slow down as they travel downward and reach the Moho?

Seismic waves generally speed up as they travel downward and reach the Moho, the boundary between the Earth's crust and mantle. This increase in speed is due to the change in density and composition of the Earth's layers, causing the waves to travel faster in the more rigid mantle layer compared to the crust.


What is the speed of seismic waves from the fastest to the slowest is it p waves s waves l wave or all three?

The speed of seismic waves from fastest to slowest is P waves (primary waves), S waves (secondary waves), and then surface waves. L waves are a type of surface wave, so they are generally slower than both P and S waves.


Which seismic wave moves through Earth at the fastest speed?

Primary waves (P-waves) move through Earth at the fastest speed among seismic waves. They are able to travel through both solids and liquids, making them the first waves to be detected after an earthquake.
