module 5- SP Flashcards
1
Q
sp log shape and depositional environments
A
retrogradational
aggradational
progradational
deep-Sea fan
2
Q
Transgression
A
ocean moves towards shore. Sea level rises
3
Q
regression
A
Ocean moves away from shore. Sea level falls
4
Q
progradational
A
Shore and seashore deposits move outward into the ocean. Overlie deeper water deposits.
5
Q
retrogradational
A
Deeper water deposits move toward land. Overlie shallow water deposits
6
