Answer:
Spring Tide
Explanation:
Normal tidal sizes become slightly larger during complete or new moons— which arise when the Moon, the sun, and the moon are almost in a straight line. It occurs two times a month. The moon looks new (dark) when it's exactly between the sun and the Earth. Once the Moon would be between the sun and earth the moon appears complete. On both situations, the sun's gravitational pull is "added up" to the Earth's gravitational pull n the moon, allowing the oceans to boom a little more than normal. This equals higher tides are marginally higher and low tides are somewhat lower than usual.
This is called as spring tide.
