| spring tide | the tidal range is the greatest |
| gravitational pull | the force exerted by the moon and the sun which causes tides |
| neap tides | occur halfway between spring tides |
| spring tides | the earth, the moon, and the sun are in a straight line |
| neap tides | occur when the earth, the moon, and the sun form a 90 degree angle |
| tidal range | the difference between levels of ocean water at high tide and low tide |
| neap tides | tides that have minimum tidal range |
| neap tides | occur during the 1st and 3rd quarters of the moon |
| neap tides and spring tides | occur every 14 days |
| spring tides | occur when the sun and moon have a maximum gravitational pull on the earth |
| tidal bore | willl most likely occur where a river empties into a long bay |
| tidal range | the difference between levels of ocean water at high tide and low tide |
| tides | the daily movements of ocean water that change the level of the ocean's surface |
| spring tides | occur when the sun and the moon's gravitational forces pull on the earth in opposite directions |
