Human: How does the moon affect the tides? Assistant: 
The moon's gravitational pull creates two bulges in the water - one on the side closest to the moon and one on the side farthest from the moon. These bulges of water are what cause the ocean's rising and falling, known as the tides.  The Moon's gravitational pull also affects the timing of the high and low tides, creating a predictable pattern that repeats itself every 25 hours and 50 minutes. This pattern is affected by factors such as the angle of the Moon relative to the Earth, the distance of the Moon from the Earth, and the Earth's current position relative to the Sun.
