Do you see the Energizer Bunny on the moon below?
Above: The "Near Side" of the Moon
Below: The "Far Side" of the Moon
Our moon is gravitationally locked with Earth due to its egg shape.
We therefore see the same "Near Side" of the moon at all times.
The moon revolves once around Earth in 27.3 days.
The moon rotates once on its axis in 27.3 days.

The Moon Size Illusion:
Have you ever noticed that sometimes the moon seems HUGE in the sky,
but other times it looks much smaller?
Your eyes play a trick with your brain.
Which is bigger?
Which is longer?
Why does the moon seem bigger when it is low in the sky, near the horizon?

Question: Why do we have tides on Earth?
Answer: The Sun and Moon's gravity pull on Earth's ocean waters...
causing ocean "tidal bulges."

High and Low Tide Zones
Most Extreme Tides on Earth: Bay of Fundy, Nova Scotia
~ Spring and Neap Tides ~
Note: The term "Spring Tide" is misleading.
It has nothing to do with the season of spring.
Spring Tides & Neap Tides
Extreme Spring Tide: Occurs when the Sun - Earth - Moon are alligned.
( Spring Tides: occur during the New Moon and Full Moon phases )
Weak Neap Tide: Occurs when the Sun - Earth - Moon are at right angles.
( Neap Tides: occur during the First Quarter Moon and Third Quarter Moon phases )
Above and Below: Spring tide allignment of the Sun - Earth - Moon.
Remember: Spring is Strong, Neap is Weak
Extreme Spring Tides: Sun-Earth-Moon in a line.
Weak Neap Tides: Sun-Earth-Moon at a right angle.
