When a seismic wave encounters a boundary, such as the interface between different geological layers, it can be reflected back, a phenomenon known as reflection. This occurs when the wave's speed changes due to differences in material properties, like density and elasticity. The angle of incidence, which is the angle at which the wave strikes the boundary, determines the angle of reflection, following the law of reflection. This bouncing back of waves is crucial for seismic imaging and understanding subsurface structures.

What is it called when a seismic wave bounces backword?
When a seismic wave bounces backward, it is referred to as reflection. This occurs when the wave encounters a boundary between different materials, causing part of the wave to return to the surface. This phenomenon is commonly used in seismic studies to analyze the Earth's subsurface structures.
When a seismic waves crosses a boundary it will change directions in the prosses of?
refraction
How did mohorovicic discover interior layers of Earth?
He noticed that seismic waves changed velocity at measurable depths. The boundary where seismic waves increased in speed is the boundary between the crust and the mantle, where seismic waves start to travel through more dense rock.
When a seismic wave crosses a boundary in what process will it change direction?
When a seismic wave crosses a boundary between different materials, it will change direction through a process called refraction. Refraction occurs because seismic waves travel at different speeds in different materials, causing them to bend as they encounter new mediums with varying densities.
What boundary did the earthquake in libson Portugal 1755 occur on?
The 1755 Lisbon earthquake occurred at the boundary between the African Plate and the Eurasian Plate. This boundary is known as a convergent boundary, where the two plates are colliding, causing seismic activity.
What is it called a seismic wave bounces backward as it reaches a boundary?
Reflection
What is it called when a seismic wave bounces backward when it reaches its boundary?
Reflection
What is it called when a seismic wave bounces backward as it reaches a boundary?
Answer: When a seismic wave 'bounces backward' and reaches a boundary, it is called Reflection. Explanation: The seismic waves are the result of the landslides, earthquakes, volcanic eruptions, explosions by humans

What is it called when a seimic waves bounces backward when it reaches a boundary?
When a seismic wave bounces backward when it reaches a boundary, it is called reflection. This phenomenon occurs when the wave encounters a change in medium or boundary, causing it to change direction and return to its source. Reflection is a key process in seismic imaging and is used to map subsurface structures in geophysics.
What is it called when a selsmic wave bounces backward when it reaches a boundary?
It is called seismic wave reflection. When a seismic wave encounters a boundary between different materials with contrasting density or rigidity, some of the wave energy is reflected back towards the source.

What is it called when seismic waves bounce backwards as it reaches a boundary?
Reflection
When a seismic wave crosses a boundary it will change directions in the process of?
When a seismic wave crosses a boundary between different materials, it may undergo reflection, refraction, or diffraction. Reflection occurs when the wave bounces off the boundary, while refraction causes the wave to change speed and bend as it enters a different material. Diffraction causes the wave to spread out as it encounters an obstacle or edge.
What plate boundary causes seismic waves?
Destructive plate boundary.
