End Morraine

Recessional Morraine

Terminal morraine
Debris collects at the front of the glacier as it moves forward

Ridge of sediment deposited when a glacier stalls in its retreat and leaves the end moraine (the crap at the end while it's moving) behind

An end moraine when its all over; the glacier melts and there's a bunch of crap left behind that is the terminal morraine
transverse dunes

Parabolic dunes

Longitudinal dunes
ridges that form perpendicular to the wind direction with plentiful sand and moderate wind.

Transverse dunes that the wind breaks thru to form crecents

Form paralell to the wind direction. High wind, plentiful sand
Glacial Striation
vs
Glacial Polish
Striation=pebbles, boulders, cobbles

Polish=sand, silt
Head Scarp
The curving part of the slump where it collapses
Berm
Horizontal landward sloping terraces that received sediment during a storm
Parabolic Dunes
Transverse dunes that the wind has broken through and now are crecent-shaped
Hogback
Narrow ridge formed when cliff retreat acts on vertical layers
Deflation
lowering of land surface by wind erosion
Breakwater
Paralell to beach to lessen the force of the waves.
Turbidity currents
turbulent much of suspended sediment that avalanches downslope. Graded beds
Subtropical deserts
20-30 degrees lattitude
cold dry air is sinking
Monsoonage
Summer, land is hotter than ocean, hot low pressure air rises.-->storms

Winter, reverses and cool high pressure air sinks-->no storms
Insellberg
Small island of rock left after cliff retreat
Toe
Bottom of slump where debris mound up
Beach Face
Steep;forms where swash scoured the land
Desert
no permenant streams
15% vegetation
25 cm rain/year
Desert Pavement
mosaic like pattern caused by lag deposits
Blowout
caused by turbulent wind vortex
