Definition
4 causes:
earthquake
astroid
landslides
underwater volcano
a large wave caused by an earthquake, asteroid, underwater volcano, or rockslide... the water column is altered (shifted up, wavelength shortened) the wave splits heading out to sea and toward shore, sea recedes |

Definition
| as waves approach a shallow shore, their velocity is slowed, and they begin to bend or refract toward shore. As they get closer to shore, the waves become increasingly parallel with it. |

|
Term
| characteristics of glaciers |
|
Definition
*zone of accumulation--amount of snow and ice exceeds amount melted, at top of glacier
*zone of ABLATION- pt where amount melted exceeds amount of ice/snow
*equilibrium line..pt where the amount melted and the amount of ice and snow equal each other
*hanging valleys- when a large glacier and a small (tributary) glacier impact with one another the large one forms a deep u shaped valley, while the sides are built up
*cirque- a bowl-shaped depression at the bottom of a mountain, usually with a lake, snow and ice, that breaks up the bedrock
*arete-hard, bedrock ridges that flank cirques, eroded from the sides |
