• How frequent are tides?• Usually 2 high tides a day and 2 low tides a

day• High tides every 12 hours• Low tides every 12 hours

Spring tides are sun, moon, earth are in a straight line

Increased gravity pull makes high tides higher, low tides lower

Neap tides are the sun, moon, and earth form right angle

Sun is competing with moon for gravity pullHigh tides are lower, low tides higher

Spring tides are at points ____ and ____Neap tides are at points ____ and _____
