    4. DDirty laundry
  3. 3Tide waves are the [blank_start]longest[blank_end] waves on earth: their wavelength is [blank_start]half[blank_end] of the Earth's circumference. These waves are known as [blank_start]forced[blank_end] waves.

  4. 4The moon's gravity [blank_start]attracts[blank_end] the ocean. Then the Motion of the Earth around the [blank_start]center of mass[blank_end] of the Earth-moon system causes a [blank_start]bulge[blank_end] on the side of the earth [blank_start]opposite[blank_end] the moon. Combined, this creates two [blank_start]bulges[blank_end].

  7. 7Lunar tides:
    1. Atides caused by gravitation & inertial interaction of the moon and Earth
    2. Btides caused by gravitation & inertial interaction of the sun and Earth
    3. Ctides caused by Luna Lovegood, because she's great
  8. 8In a 24h solar day, the moon moves [blank_start]12.2[blank_end] degrees eastward. The earth must rotate another [blank_start]50[blank_end] minutes to again place the moon at the highest position.
