What two processes can affect the path of seismic waves?
Seismic wave reflection and refraction are the two processes that can affect the path of seismic waves. Reflection occurs when seismic waves bounce off a boundary between different materials, while refraction occurs when seismic waves change direction as they pass from one material to another with different properties.
What is seismic profilling useful for?
Seismic profiling is useful for identifying subsurface structures and characteristics by analyzing the reflection and refraction of seismic waves. It helps in locating potential oil, gas, and mineral deposits, as well as understanding the geology of an area for engineering and construction purposes. Seismic profiling is also used in assessing seismic hazards and risks for earthquake-prone regions.
When a seismic waves crosses a boundary it will change directions in the prosses of?
refraction
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.
How is physics related to seismology?
Physics is related to seismology because seismology relies on principles of physics to study and understand the behavior of seismic waves generated by earthquakes. Concepts like wave propagation, energy transfer, and wave reflection/refraction are all essential in seismology to analyze seismic data and interpret subsurface structures. By applying physics principles, seismologists can estimate the location, magnitude, and source characteristics of earthquakes.
How do you differentiate a reflection event from refraction event in a seismic record?
refraction event is a stright line and reflection is a hyperbolic event

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 are the differences between seismic reflection and refraction methods in geophysics and how are they used to study the Earth's subsurface?
Seismic reflection and refraction are two methods used in geophysics to study the Earth's subsurface. Seismic reflection involves sending seismic waves into the ground and recording the reflections that bounce back from different rock layers. This method is used to create images of subsurface structures like faults, rock layers, and oil and gas reservoirs. Seismic refraction, on the other hand, involves measuring the bending of seismic waves as they pass through different rock layers. This method is used to determine the velocity of seismic waves in different materials, which can help in mapping the depth and thickness of subsurface layers. Both methods provide valuable information about the Earth's subsurface, helping geophysicists understand the composition and structure of the ground beneath our feet.
What is it called when a seismic wave bends as it passes from liquid to solid rock.?
it is called refraction
What is the band around the earth where seismic waves are not detected?
The band around the Earth where seismic waves are not detected is known as the seismic shadow zone. It exists between 105 and 140 degrees away from the earthquake epicenter. Seismic waves are not detected in this region due to the refraction and reflection of waves in the Earth's interior layers.
What is it called when a seismic wave bend as it passes from liquid to solid?
refraction

When a seismic wave boundary it will change directions in the process of?
refraction
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
Why do shadow zones exist?
P-waves refract as they travel through Earth so do not rach all other pars of the earth's surface. Also S-waves can't travel through liquids and so can't pass through the earth's outer core which also causes a shadow zone.
