What are seismic waves and what information information do they give about earthquakes?
Earthquakes are when the seismic plates on the earths crust move after pressure from on another is exceeded, seismic waves are produced after an earthquake, and can turn into a tsunami.
Why do seismic waves speed up beneath the surface of continents?
Because earths crust is denser than the mantle
The crust is only what of earths thickness?
half of earths layer
What does seismic mean?
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
What is the earths under crust surrounded by?
Earths under crust surrounded by Upper Mantle (35-60 km) .The mantle is composed of sillicate rocks that are rich in iron and magnesium relative to the overlying crust.
When the shift occurs in the earths crust the energy radiates as what?
When a shift occurs in the Earth's crust, the energy can radiate as seismic waves. These waves travel through the Earth's interior and can be detected and measured by seismographs. Depending on the type of fault movement, the seismic waves produced can be either compressional (P-waves) or shear (S-waves).
When is earths Crust destroyed?
The Earth's crust is destroyed when subduction occurs.
What occurs when the earths crust is squeezed into smaller space?
compression
What often occurs along faults or breaks in earths crust where movement occurs?
earthquakes

Where do most faults occurs?
Most Faults Occur Where The Earths Crust Is Extended
What occurs when rocks layers bend due to stress in the Earths crust?
I found that folding happens
The Mohorovicic discontinuity occurs between the crust and the?
The Mohorovicic discontinuity occurs between the Earth's crust and the mantle. It marks the boundary where seismic waves change speed, indicating a change in the composition of the Earth's layers.
Is the focus of an earthquake the location inside the earths crust where the seismic event originally takes place?
yes couldnt say it better myself
What is the name of the person who specializes in the study of earthquakes and other movements of the earths crust?
A seismologist specializes in the study of earthquakes and other movements of the Earth's crust. They analyze seismic waves to understand Earth's internal structure and study the causes and effects of seismic activity.
How does a strike slip fault lead to an earthquake?
An earthquake occurs deep in the earths crust caused by the displacement of two faults in the crust. Directly above the fault on the earths surface is called the epicenter. Which shows the aftermath of the strike slip fault that occured in the earths crust. So the strike slip fault is the effect of the displacement of the crust at that point deep in the earths crust which causes an earthquake to happen whenever there is a displacement of two faults.
