continental rise
one side has shelf and the other side has land
pericontinental sea
non-existant in present day, a sea that recieved sediment from more than one side
epicontinental sea
dumps sediment into a delta dispersing out into the floor
sediment plumes
because of the spinning of the earth most of the particles in the ocean are deflected to the left
corialis effect
waves and storms are more important than tidal processes in these shelves
storm and wave dominated shelf
depth of the water in which orbital are no longer impacting the sea floor
wave base
during storms, net sediment is deposited seward
key structure is hummocky cross beds during storms
storm and wave dominated shelf
water is piled up to shore due to tides and winds giving a deeper current back to the ocean
geostrophic currents
couplets of fine and course grain sediments generally deposited by tides
tidalites/tidal rhythmites
