14. PREDATOR
ORGANISMS THAT EAT OTHER ORGANISMS

15. PREY

17. INTERTIDAL ZONE
THE REGION THAT LIES BETWEEN THE LOW AND HIGH TIDES, SOMETIMES OCEAN AND SOMETIMES DRY LAND. ALSO KNOWN AS THE LITTORAL ZONE

20. SUBLITTORAL ZONE
EXTENDS FROM THE LOW TIDE LINE TO THE EDGE OF THE CONTINENTAL SHELF

21. NERITIC ZONE
THE VOLUME OF WATER THAT COVERS THE CONTINENTAL SHELF

23. PELAGIC ENVIRONMENT
THE ENTIRE VOLUME OF WATER IN THE OCEAN AND THE MARINE ORGANISMS THAT LIVE ABOVE THE OCEAN FLOOR. ALSO CALLED THE OPEN OCEAN OR OPEN SEA ZONE

24. EPIPELAGIC OR EUPHOTIC ZONE
TOP LAYER OF THE OCEAN WHERE ENOUGH SUNLIGHT PENETRATES TO ALLOW PHOTOSYNTHESIS TO OCCUR(PHOTOSYNTHETIC ZONE OR PHOTIC ZONE)

25. MESOPELAGIC ZONE
TWILIGHT ZONE-SOME SUNLIGHT PENETRATES BUT NOT ENOUGH FOR PHOTOSYNTHESIS TO OCCUR (DISPHOTIC ZONE)

26. BATHYALPELAGIC ZONE
PART OF THE OPEN OCEAN ZONE THAT EXTENDS FROM THE CONTINENTAL SLOPE TO ABOUT 2000M, (APHOTIC)LIGHT DOES NOT PENETRATE THIS ZONE (BATHYAL ZONE)

27. ABYSSOPELAGIC ZONE
ABYSSAL ZONE- PART OF THE OPEN OCEAN ZONE EXTENDING FROM THE BOTTOM OF THE BATHYAL ZONE TO THE ABYSSAL PLAIN, (APHOTIC) NO LIGHT AND FREEZING. ALSO KNOWN AS THE ABYSS

28. HADALPELAGIC ZONE
HADAL ZONE- (APHOTIC) DEEPEST BENTHIC ZONE, WHICH CONSISTS OF THE FLOOR OF THE OCEAN TRENCHES, AND ANY ORGANISMS FOUND THERE. GREATER THAN 6,000 METERS

29. WAVES, CURRENTS, AND TIDES
THE 3 BASIC MOTIONS OF OCEAN WATER

30. WAVES
THE UP AND DOWN MOTION OF THE OCEAN

32. WAVELENGTH
THE DISTANCE FROM 1 WAVE CREST TO THE NEXT OR 1 WAVE TROUGH TO THE NEXT

35. CREST
THE HIGHEST POINT OF A WAVE

36. TROUGH
THE LOWEST POINT OF A WAVE

37. WAVEHEIGHT
THE VERTICAL DISTANCE BETWEEN THE WAVE CREST AND THE WAVE TROUGH

38. TSUNAMIS
TIDAL WAVES

40. SURFACE CURRENTS
CONTROLLED BY: GLOBAL WINDS, CORIOLIS EFFECT, AND CONTINENTAL DEFLECTIONS (GULF STREAM), WARM AND COLD WATER CURRENTS

42. CORIOLIS EFFECT
EARTH’S ROTATION CAUSES SURFACE CURRENTS TO CURVE TO THE RIGHT IN THE NORTHERN HEMISPHERE AND THE LEFT IN THE SOUTHERN HEMISPHERE

44. GLOBAL WINDS
WINDS BLOWING ACROSS EARTH’S SURFACE CAUSING SURFACE CURRENTS

46. CONTINENTAL DEFLECTIONS
WHEN SURFACE CURRENTS MEET CONTINENTS THEY ARE DEFLECTED

47. DEEP CURRENTS
DUE TO TEMPERATURE AND SALINITY, DENSITY OF WATER CHANGES CAUSING DIFFERENT CURRENTS TO RUN AT DIFFERENT DEPTHS AND SPEEDS

49. LONGSHORE CURRENTS
CURRENTS THAT ARE MORE PARALLEL TO THE SHORELINE

51. RIP TIDE
CURRENTS THAT RETURN TO THE OCEAN IN A POWERFUL NARROW FLOW

54. UPWELLING
RISING OF DEEP, COLD WATER CURRENTS TO THE OCEAN’S SURFACE

56. EL NINO
PERIODIC CHANGE IN THE LOCATION OF WARM AND COOL SURFACE WATERS IN THE PACIFIC OCEAN THAT AFFECTS WEATHER

58. SWELL
ROLLING WAVES THAT MOVE IN A STEADY PROCESSION ACROSS THE OCEAN

59. WHITECAPS
A WHITE, FOAMING WAVE WITH STEEP CREST THAT BREAKS IN THE OPEN OCEAN

60. STORM SURGE
LOCAL RISE IN THE SEA LEVEL NEAR SHORE CAUSED BY STRONG WINDS FROM A STORM- OFTEN THE MOST DESTRUCTIVE PART OF A HURRICANE
