Due to water’s high specific heat, water transports a large amount of energy. In fact, the Gulf Stream alone transports more than 100 times the world's energy demand.
Recall that the equator is impacted most greatly by the Sun, and is thus the hottest part of the planet. This will help you remember that ocean currents transfer heat from equatorial regions (hottest) to higher latitudes.
Remember that the Moon takes 24 hours and 50 minutes to rotate once around the Earth, so the Moon is over the same location every 24 hours and 50 minutes. Since high tides occur twice a day, one arrives each 12 hours and 25 minutes.
