The document discusses the causes and types of tides. The moon's gravity pulling on the earth's oceans as both orbit the sun causes high and low tides. Spring tides occur when the moon, earth, and sun are aligned, creating the largest difference between high and low tides. Tide times vary slightly each day as the positions of the celestial bodies change their combined gravitational effects.

- 2. There are two types of tides, high and low, and special tides called spring and neap tides!
- 3. As the moon orbits around the earth and as they orbit around the sun together travel around the sun, the combined gravitational forces cause the world's oceans to rise and fall. Tides also change everyday, as the earth, moon, and sun orbit, their positions constantly shift, making the gravity effects change, this makes tide times a bit different every day!
- 4. Spring tide: When the Moon, Earth, and Sun fall in a straight line, which we call syzygy, we can see the greatest distance between high tide and low tide.
