Key Concepts

Spring Tides

Spring tides occur when the Earth, Moon, and Sun are aligned, typically during the full and new moon phases. This alignment amplifies the gravitational effects of the Moon and the Sun, resulting in higher than normal high tides and lower than normal low tides.

Lunar Influence

The Moon exerts the strongest gravitational influence on Earth’s tides due to its proximity, making it the primary driver of tidal movements. Its gravitational pull generates the major tidal bulges and plays a crucial role in determining tide magnitude.

Ocean Tides

Ocean tides are the periodic rise and fall of sea levels primarily caused by gravitational interactions between the Earth and celestial bodies. They are influenced by the motions of the Moon and the Sun, along with local geographic conditions such as the shape of the coastline and seafloor.

Tidal Forces

Tidal forces arise from the differential gravitational pull exerted by celestial bodies on different parts of the Earth. This difference creates two tidal bulges on opposite sides of the planet, leading to the cyclical pattern of high and low tides.
