were land and a body of water meet
movement of materials by water
the accumulation of eroded particles
ripples on the water caused by wind
groups of waves travelling together
wave trains
breaking waves
can break solid rock and reposition the peoces
pounding surf
the intervals between breaking waves
wave period
any area of the shoreline made uo if materials deposited by waves
waves hit the beach at a slight angle but retreat perpendicular to the shore
wave angles
the movement of watetr near and parellel to the shoreline
longshore current
an underwater or exposed ridge of sand, gravel or shell material
sand bar
occurs when an exposed sand bar is connect to the shoreline
barrier spit
produces a variety of features along the shoreline
wave erosion
steep slopes form when waves erode and undercut rocks
sea cliffs
what is a type of alpine glacier
valley glacier
huge contenetal masses of ice that may form across and entire continent
contentetal glaciers
cover over millions of sq. km with ice. anarctica is an example
contenetal ice sheets
what is the largest type of contenetal glaciers
contenetal ice sheets
an area wher ice is attached to the ice sheet but is resting over oopen water
ice shelf
large pecies of ice that break of an ice shelf and drift into the ocean
whats bigger an icebirg or a glacier
the process by which an icebirg is made
what are the two ways an icebug can be made
1)"rolling" bottom ice melts iceburg slips and rolls

2)"sliding" they ice crystals go ontop of another and then fall down slowly
a large crack that forms where the glacier picks up speed or flows over a high point
sharp, pyramid-shaped peaks that form when 3 or more cirques erode the mountain
bowl-like depresions where glacial ice cut back into mountains
jagged ridges that form between 2 or more cirques cutting into the same mountain
formed when a glacier erodes a river valley form its original "v" shape to "u" shape
u shaped valleys
smaller glacial valleys that join the deeper main valley
hanging valleys
grooves on rocks caused by glaciers
general term used to describe all materails carried and deposited by glaciers
glacial drift
rock material that has been sorted and deposited in layers by water flowing from melted ice
straified drifts
sorted material carried by streams flowing form the melting glacier that are deosited in a broad area in front of glaciers
outwash plain
depression left when a block of ice from the glacier is left in the outwash plain
unsorted rock material that is deposited directly by the ice when it melts
means that till is made up of different sizes of rock material ranging from large glaciers to fine glacial silt
unsorted till
form ridges along the edges of glaciers
form when two different valley glaciers with lateral moraines meet
medial moraines
a large crack that forms where the glacier picks up speed or flows over a high point
sharp pyramidshaped peaks that form when3 or more cirques erode the moutain
bowl-like deppressions where glacialice cuts back into the mountain wall
formed when a glacier erodes a river valley from its original v-shaped
u shaped valleys
smaller glacial valleys that join the deeper main valley
hanging valley
groves on rocks caused by glaciers
form along each side of a glacier
lateral moraine
are the unsorted materials left beneath a glacier
ground moraines
form when eroded materials is dropped at the front of the glacier
terminal morianes
what are the 4 types of moraines
medial, terminal, lateral, and ground moraines
is the movenment of any material such as rock,silt or snow downslope
mass movement
the steepest angle or slope at which loose material will not slide downslope
angle of repose
a group of loose rocks fall down a steep slope
rock slide
the sudden and rapid movement of a large amount of material downslope
a block of material moves downslope over a curved surface, example of a landslide
a rapid movement of a large mass of mud
mudflows of volcamic origin
an extreamly SLOW movement of materials downslope
priduces a variety of features on the shoreline
wave erosion
steep slopes that erode and undercut rock
sea cliffs
offshore columns of resistnat rocks that were once connected to the main land
sea stacks
form when wave action continues to erode a sea cave cutting completly through rock
sea arches
form when waves cut large holes waves erode and undercut rocks
sea caves
finger shaped projection that occurs when cliffs formed of large rocks erode slowly
form when a see cliff is worn back producing a nearly level platform beneath the water at the base of the cliff
wave cut terrace
the movement of sand sized particles by a skipping and bouncing action in the direction of the win
the lifting and removal of sediment by wind
hard rocky surface consisting of pebbles and small broken rocks caused by deflation
desert pavement
wind blown depressiosn in the sand
depression hollow
the grinding and wearign down of sediments
mounds of wind deposited sand
think deposits of wind blown sediments
an enormous mass of moving ice
