Nothing whatsoever.
The Moon is apparently shrinking a tiny bit, because the core of the Moon has been cooling and shrinking - but the net effect, from 250,000 miles away, is precisely zero. As long as the mass of the Moon stays the same (and it is) and the ORBIT of the Moon remains the same (and it is!) then the gravitational force on the tides is entirely unchanged.
Depending on depth of ocean, the diatoms size shrinks
After the full moon phase, the moon's illumination begins to decrease as it moves towards the new moon phase. This is known as the waning phase, where less and less of the moon's illuminated surface is visible from Earth.
waning
it shrinks
The ocean moves in and out because of something called the tide. This happens due to the magnetic pull of the moon.
it moves der!!
it causes a high tide in the ocean
asteriods would hit earth,spinning faster,ocean tides reduced etc
It shrinks
It shrinks
a tide
nothing it only shrinks when dried
