.....and for the precious things put forth by the moon,...
Deuteronomy 33:14
"Tides are caused by gravity. The closer two things are, the stronger 
the
force of gravity between them, and the faster they accelerate toward
one another.
The oceans, however, are not solid. They are free to react to the sun’s
gravitational pull. The ocean on the near side would literally fall
toward the sun faster than the earth and the ocean on the far side would
literally fall more slowly than the earth.
Solar tides occur twice every day, 12 hours apart, as the earth spins.
But since the moon is orbiting the earth, it takes 24 hours and 50
minutes for the moon to get to the same place in the sky as it was the
day before.
Thus, the solar and lunar tides happen at different
frequencies. When the solar and lunar tides are lined up, either at a
full moon or a new moon, we experience above average spring tides. They
occur every two weeks, not just in the Spring!
When the lunar high tide
happens at the same time as the solar low tide, and vice versa, the two
tides cancel each other out.
The smaller tidal effect caused by the sun
is subtracted from the larger tidal effect caused by the moon. At these
times we have below average ‘neap’ tides.
There is an amazing design aspect to this system. The moon is just the
right size and just the right distance to produce tides that gently
flush our coastlands.
---If the tides were much stronger, the earth would
experience twice-daily tsunamis that would rip apart rocks and destroy
any living thing even within great distances from the shore.
---If the
tides were much smaller, bays and estuaries would be stagnant and
inhospitable to life.
The earth-moon system is unique in our solar
system. It defies the possibility that it has arisen by chance. Thus,
the presence of tides points to intelligent design, by a loving God, who
gave us a wonderful place to live." CMI
