Look at the images to the left. Both pictures show the exact same place, just hours apart. What is happening in the top image?

Spring & Neap Tides
The Sun plays a role in affecting how large the tidal range is on any given day.
The Sun's gravitational pull is weaker than the Moon's, but it can help the Moon pull high tide higher OR it can cause some water to flow away from the high tide.
7
Spring and Neap Tides
Spring tides occur when the Sun and Moon both pull on high tides, causing extreme tide differences.
Neap tides occur when the Sun and Moon form a right angle, pulling on different tides. This reduces the tide differences.
8
Spring Tides
During the New and Full Moon phases, the Sun and Moon are aligned. They both pull on the high tides, making them higher than normal. With most water moving into the high tides, low tides are lower than normal.
So Spring Tides have extreme differences between high and low tides.
9
Neap Tides
During the First and Last Quarter Moon phases, the Sun and Moon form a right angle. The Moon pulls on high tide (as always) while the Sun pulls on low tide. The Sun's pull causes some water from the high tides to move to the low tides.
As a result, Neap tides have less change between high and low tides.

This chart shows the tidal ranges and lunar phases for Spring Tides (pink) and Neap tides (green).
