Fold your paper hamburger

• Put the fold on the top
• Draw a wave
• Label
• Crest
• Wavelength
• Wave height
• Trough

Wave Height
3
On Front Include

• Waves
• Get energy from wind blowing across the waters
  surface
• Near shore- wave height increases, wavelength
  decreases because friction with ocean floor slows
  it down

Wave

• Movement of energy through a body of water

6
Wavelength

• Horizontal distance between crests

7
Frequency

• The number of waves that pass a point in a
  certain amount of time

8
Wave height

• The vertical distance from crest to trough

9
Breakers

• White capped waves that crash onto shore

10
Tsunami

• A giant wave usually caused by an Earthquake

11
Longshore Drift

• The movement of water and sediment down a beach
  caused by waves coming in to shore at an angle

12
Rip Current

• A rush of water that flows rapidly back to sea
  through a narrow opening in a sandbar

14
Barrier Beach

• A natural landform that protects shorelines from
  wave action. Long sand deposits that are parallel
  to shore

15
Sand Dune

• Hills of windblown sand. Make beaches more
  stable. Another natural landform that helps
  protect beaches reduce erosion

16
Groin

• A wall made of rocks or concrete that is built
  outward from a beach to reduce erosion

17
Tide

• The daily rise fall of Earths waters on its
  coastlines. Tides are caused by the interaction
  of the earth, moon sun--- GRAVITY

18
Salinity

• The total amount of dissolved salts in a water
  sample
• Ocean is 3.5 salt

19
Coriolis Effect

• The effect of Earths rotation on the direction
  of winds and currents

20
El Nin?o

• A climate event that occurs every 2-7 years in
  the Pacific Ocean, during which winds shift and
  push warm water toward the coast of S. America.
  (FOR MINNESOTA- THIS USUALLY MEANS A WARMER
  WINTER)

21
Upwelling

• The movement of cold water upward from the deep
  ocean that is caused by wind
