I is for lntensity. This is how strong anearthquake is.

J is for Jello. A wiggling Jello cube is a good

example of how buildings "wiggle" during anearthquake.

K is for Kinematic. Kinematic is the generalmovement patterns and directions of the earthsrocks that produce rock formations.

L is for Lava. Lava causes sea floor spreading.Sea floor spreading causes earthquakes.

R is for Richter Scale. The Richter Scale wasdesigned by Charles Richter. He applied anumber to how powerful an earthquake was.

S is for Seismosraph. This is a machine thatrecords the P-Waves produced by anearthquake.

T is for Tsunami. A tsunami is a really big wavethat can go up to speeds of 800mph. Tsunamisare often caused by earthquakes in the oceanfloor.

U is for Uplift. This happens when hrvo plates ofthe earth's core collide and one goes above theother.

V is for Volcano. Earthquakes often occurwhere Volcanos are, due to the movement ofmagma in Volcanos.

W is for Weqener. Alfred Wegener. He came upwith the theory of continental drift. His theoryhelped scientists learn about how the earthsplates shift and move.
