“Shoreline Processes”
  
What is a “Beach” anyways?!
•	Beach
–	Accumulation of sediment near water
Do Beaches Change?
Forces change beaches!
–	Push/Pull or waves & currents

–	This creates shoreline features.

Forces that change Beaches:
•	Abrasion
–	Grinding of moving sediments
–	“Sand-papering”

•	Refraction
–	Bending of waves
–	Where sediment is deposited

•	Longshore Transport
–	Sideways shore currents
–	Erosion = movement

2 Types of Shoreline Features
•	Erosional Features
–	Created by moving sediment away
•	Depositional Features
–	Created by leaving a pile of sediment

Erosional Features:
•	Wave-Cut Cliff
–	Flat cliff along water

•	Platform
–	Benchlike surface along cliff

•	Sea Arch
–	2 caves join

•	Sea Stack
–	Arch falls down

Depositional Features:
•	Spit
–	Long “finger” of sand
–	Hook at end (usually)

•	Bar
–	Shallow area
–	Sand peaks out of water

•	Tombolo
–	Connects island to mainland
