types of stress
kinds of faults
changing earths surface
types of seismic waves
measuring earthquakes
100
when some rocks to become brittle and snap.
What is stress caused by?
100
in rocks,the rocks the rocks will break creating a fault.
What is enough stress builds up by?
100
the movement of earths plates can fold stretch and uplift the crust
What is The forces produced by?
100
during an earthquake seismic waves race out from the focus in all directions
What is a pebble thrown into a pond an earthquake produces vibration called waves?
100
people want to know how big was the earthquake
what is When an earthquake occurs?
200
like road tar softened by the sun
What other rocks bend slowly?
200
the rock of the crust where rocks surface slip past each other.
What is a recall that a fault is a break in?
200
anticlines and synclines folded mountins fault,fault-block mountins,and plataus
these landforms included?
200
travel outward during earthquake, seismic waves race out from the focus from all directions
these waves carry energy as they?
200
their in tensity or strength at a given place.
What is The mercalli scale was developed to rate earthquakes according to?
300
THE SLOW SHIFT OF THE EARTH'S PLATES CAUSES THESE CHANGES
HOW DOES STRESS AFFECT THE CRUST?
300
up or down or sideways
when the rocks move what ways does it move?
300
earth is carring the energy released during an earthquake.
when seismic waves are vibrations that travel though?
300
it's intensity varies at different locations.
the same earthquake can have different marcalli ratings because?
400
tension,compression,shearing
What are the types of stress
400
a normal fault
tension in the earth's crust pulls rock apart causing
400
crust to fold.
sometimes plates movement causes the?
400
earth's interior and across the surface.
seismic waves carry energy from an earthquake away from focus though?
400
from the epicenter
for example an earthquake's intensity generally decreases with distance
500
it folds or breaks
a type of stress called compression squeezes rock until
500
the other block of the rock.
the fault is at an angle,so one block that lies above?
500
alaska
When a powerful earthquake ruptured the denali fault in
500
some of the waves energy
this happens because earth materials absorb
