Upper Elementary Science - II
3.25 Tides

The tides are the cyclic rising and falling of Earth's ocean surface caused by the gravitational forces of the Moon and the Sun acting on the Earth.

Types of Tides

  • Spring Tides
  • Proxigean Spring Tides
  • Neap Tides
Spring Tides
Spring tides are especially strong tides. They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon. The name "spring tide" is derived not from the season of spring but rather from the verb "to jump" or "to leap up."

Proxigean Spring Tide
The Proxigean Spring Tide is a rare, unusually high tide. This very high tide occurs when the moon is both unusually close to the Earth and in the New Moon Phase. It occurs once in 1.5 years.

Neap Tide
Neap tides are especially weak tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). Neap tides occur during quarter moons.
