Document Summary
You can describe a wave by the following: how it changes over time, spatial coordinates. Though waves move left or right, objects in a wave move up and down (like doi(cid:374)g (cid:858)the (cid:449)a(cid:448)e(cid:859)) Wave qualities: period- the change in time versus position (ie. it takes 10 seconds for the ball to bob up, amplitude- the change in position with time. On a graph, this is the distance of the peak from the distance halfway down. (ie the ball bobbed up and down 3 feet: wavelength- the change in position with distance. This graph is nearly identical to a graph of the amplitude: frequency- the number of peaks that happen in a given amount of time. (cid:1870)(cid:1857)(cid:1869)(cid:1857)(cid:1866)(cid:1855)= 1(cid:1868)(cid:1857)(cid:1870)(cid:1867)(cid:1856) Most big tsunamis happen at ocean trenches: convergence on the plate boundary, reverse faulting. The tsunami warning system was established in 1946 following a devastating tsunami in hawaii. Pacific ocean-wide network of: seismic station, tsunami buoys, coastguards, civil defense.
