What else can I help you with?
Where does the Mohorovicic discontinuity occur?
Crust and Mantle.
What areas under the earth do earthquake waves bounce off?
Every discontinuity inside the earth can reflect seismic waves. These occur between major layers (crust, mantle, outer core, inner core) and are named after scientists (Mohorovicic and Gutenberg for example).
What area do seismic wave change dramatically?
Seismic waves can dramatically change in velocity and direction when they encounter boundaries between different types of rock or geological formations. These changes, known as refraction and reflection, occur at interfaces with contrasting physical properties, leading to the bending or bouncing of seismic waves. The behavior of seismic waves at these boundaries provides valuable information about the Earth's interior structure.
What is likely to occur at a plate boundary where oceanic crust collides with crust?
tides will occur.
What is likely to occur at a boundary where oceanic crust collides with continental crust?
tides will occur.
Where does the most present day faulting of rock occur?
at boundaries between moving parts of the crust
When does volcanoes occur more often?
Volcanoes occur at divergent and convergent plate boundaries due to the fact that crust is either being destroyed or created. Volcanoes also occur at hotspots, for example in Hawaii. Hotspots occur where the crust is particularly thin or weak, and plumes of magma rising from the asthenosphere (between upper mantle and the crust) end up giving rise to volcanoes or volcanic islands.
Where do subduction's occur?
Where crust is destroyed
What earth crust?
The crust is the upper layer of the earth. It is where the movement of plates occur due to which earthquakes occur. The Earth's crust is a thin layer of rock, like skin on an apple.
Convegent boundarie what changes to the crust occur?
The crust is compressed into mountains (if it is continental crust) or subducted back into the mantle if it is oceanic crust.
What is discontinuity?
A continuous spectrum contains all the wavelengths. A discontinuous spectrum has stripes of specific colors and can be used to identify the elements making it
Why do most earthquakes occur in the litosphere?
the crust
