Lunar/Solar
Tides (exaggerated!)
From the
text, Horizons by Seeds
What are tides? More complex than
what you see on Baywatch!
Gravity from the moon and sun pull on
Earth. Gravity weakens with
distance, so the pull is strongest on the near side, weakest
on the far side.
The sun is more massive than the
moon, but farther away, so its tidal effect is smaller.
Actual flow of water around the world
is very complex and not fully understood!
