Tide Facts

Back 2

1) It takes just over 6 hours for an area to go from high to low tide
2) The difference between high and low tide varies from place to place

Front 3

Where do high and low tides occur?

Back 3

High tides occur directly across from the moon at the area closest to the moon as well as the area furthest from the moon. Low tides occur on the other 2 sides of the earth, not directly across from the moon.

Spring Tides

Back 4

1) tides that occur at new & full moon
2) sun, earth, & moon are aligned
3) sun's gravity assists moon's gravity
4) causes more extreme tides (high tide is higher than normal, low tide is lower than normal)

Neap Tides

Back 5

1) occur at waxing & waning quarter moons
2) sun, earth, and moon form a right angle
3) sun's gravity works against the moon's gravity
4) causes less extreme tides (high tide is lower than normal, low tide is higher than normal).
