tsunami answer

QuestionAnswer
an earthquake that occurs after a larger earthquake in the same area aftershock
the point beneath earths surface where rock break causing an earthquake focus
a type of sesmic waves that moves on the ground up and down or side to side s waves
a force that acts on rock to change its shape or volume stress
a type of fault were rocks on either side move past each other sideways with little up or down motion strike slip fault
stress that squeezes rock until it folds or brakes compression
a scale that rates earthquakes acording to their intesity and how much damage they cause mercali scale
a large wave produced by an earthquake on the ocean floor tsunami
Potential Tsunami Locations Subduction Zones
what are Subduction Zones an area where an oceanic plate is being forced down into the mantle by plate tectonic forces.
Convergent Plate Boundary occurs between two oceanic plates one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density.
volcanic island formation pt 1 The subducting plate is heated as it is forced deeper into the mantle, and melts. Magma spots created as a result,magma is lower density than the rock material
Volcanic island formation pt.2 It ascends by melting and fracturing through the rock material.Magma chambers at the surface form a volcanic cone. early stages of this boundary the cones will be in deep ocean, later grow above sea level
example of Convergent Plate Boundary - Oceanic Japan, the Aleutian islands and the Eastern Caribbean islands of Martinique,St. Lucia and St. Vincent and the Grenadines are examples of islands formed through this type of plate boundary
Convergent Plate Boundary - Continental The two thick continental plates collide and both of them have a density that is much lower than the mantle, which prevents Subduction
Convergent Plate Boundary - Continental example The Himalaya Mountain, and The Appalachian Mountain Range,are the best active examples of this type of plate boundary
