    {https://spaceplace.nasa.gov/review/seasons/seasons.en.jpg} Earth's tilt is the reason for the seasons. View of Earth in relation to sun during each of the four seasons. The hemisphere receiving the direct rays of the sun has summer while the hemisphere tilted away from the sun, thus getting its rays from more of an angle, has winter.

    An animation of Tides
    {https://oceanservice.noaa.gov/education/kits/tides/media/tide05a_300.gif} Animation of lunar day
    Unlike a 24-hour solar day, a lunar day lasts 24 hours and 50 minutes. This occurs because the moon revolves around the Earth in the same direction that the Earth is rotating on its axis. Therefore, it takes the Earth an extra 50 minutes to “catch up” to the moon. Since the Earth rotates through two tidal “bulges” every lunar day, we experience two high and two low tides every 24 hours and 50 minutes. Here, we see the relationship between the tidal cycle and the lunar day. High tides occur 12 hours and 25 minutes apart, taking six hours and 12.5 minutes for the water at the shore to go from high to low, and then from low to high.
    {https://oceanservice.noaa.gov/education/kits/tides/media/tide06a_450.gif} Animation of spring and neap tides
    Together, the gravitational pull of the moon and the sun affect the Earth’s tides on a monthly basis. When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides — both commonly called spring tides. One week later, when the sun and moon are at right angles to each other, the solar tide partially cancels out the lunar tide and produces moderate tides known as neap tides. During each lunar month, two sets of spring and two sets of neap tides occur (Sumich, J.L., 1996).
