QExplain how the Moon causes Earth’s ocean tides. Why are there two high tides?

This requires a bit of explanation , I'll keep it simple , I hope it can continue . The moon and Earth pull each other through gravity, the Earth is 81 times as massive as the moon especially turned toward Earth . However, the Earth does not get pulled into a little moon , and it is this movement that causes tides . The speed at which the Earth moves the moon is determined by averaging all the gravity pulling it , however , the side closest to the moon more than average and pull the far end gets less traction . The result is that the water in the oceans of the moon closer to the moon wants more faster than the average for the earth , for what goes on itself creating a high tide. The water on the far side of the Earth is becoming less pull than average so it is left behind , as a result , stands on the far side . There you have it , two tides a day , both created by the gravity of the moon . Hope this makes sense to you .

Moon gravity pulls the water in the oceans to it. When the moon is in time determines the high tide and low tide.
