1. Ocean Motion
OCEAN MOTION!

2. Waves

3. The up and down movement of surface water. Waves are really energy!
Water moves in a circular motion, while the energy moves forward!

4. What makes a wave?
Most waves are caused by wind and can grow in size according to:
Speed of wind
How long the wind blows
How far (distance) the wind blows

5. Parts of a Wave

7. Giant waves caused by earthquakes and volcanoes
Tsunamis
Giant waves caused by earthquakes and volcanoes

8. Storm Surge
Large domes of water caused by low air pressure during hurricanes and tropical storms.

9. Huge wave formed by large storm waves joining together
Rogue Waves
Huge wave formed by large storm waves joining together

10. Streams of water that flow like rivers through the ocean.
Unlike waves, currents do move water forward!
Caused by wind patterns and different water densities.

11. determine weather & climate
Oceans
have warm and cold
currents.
There are 7 major
ocean currents
These currents help
determine weather & climate
patterns

13. The Gulf Stream –a well known Surface Current!
Part of a large current that carries warm water up the Southeastern coast of America as well as over to Western Europe.

15. Types of Currents Surface Current: Flow across surface of ocean
Caused by prevailing winds (Gulfstream)
Shoreline Currents: local currents that run along the shore
caused and changed by winds and shifting sand
Longshore Current: type of shoreline current that carries large amounts of beach material from one place to another.
Rip Current: shoreline current that flows away from beach
(very dangerous to swimmers!)
Deep Ocean Currents – caused by differences in water temperature.
Cold water is heavier than warm water so it sinks.

16. Currents do not move in a straight line
because Earth’s rotation causes them to bend.
Currents in Northern Hemisphere flow clockwise
Currents in Southern Hemisphere flow counter-clockwise

17. TIDES

18. Tides
The daily rise and fall of the level of the ocean. Caused by the pull of gravity from the sun and moon.

19. The bulges of water
on either side of the earth
are called
HIGH TIDES
The low-water levels
LOW TIDES.
