Geologic Processes Forming Earth Surface
Geologic Processes Forming Earth Surface
Name: Ella Schwartz
The Earth is a dynamic, ever changing planet. The interaction between the hydrosphere and the lithosphere reshapes the surface over and over again. It is a constant process of building up and tearing down. While we aren't alive for all the changes, the evidence is around us, and we use models to simulate the long term changes.
Let's explore four geologic processes in our workbook.

Coastline Erosion
WAVE-CUT PLATFORM
HEADLANDS
Large crack opened by hydraulic action.
The cave becomes larger.
The arch is eroded and collapses.
The stack is eroded forming a stump.
The crack grows into a cave from hydraulic action and abrasion.
The cave breaks through the headland forming a natural arch.
This leaves a tall rock stack.
The grinding and wearing down of rock surfaces by other rock or by sand particles.
Desert Pavement
The removal of fine sediment by wind
Deflation
Made up mostly of pebbles and small broken rock, it is the surface left behind when sand is blown away.
Dunes
Mounds of wind-deposited sand.
Abrasion
Thick deposits of windblown, fine-grained sediment
Loess
What do you notice about the top of the dune and the wind direction?
The wind pushed the top of the sand dune in the direction it is blowing.
