If you are checking a cell for a zero value and the cell is blank, the test evaluates to true. For example, if you have the following formula in cell A1 =IF(B1=0,"zero","blank") and B1 is blank, the formula returns "zero" and not "blank" as expected.
If the range might contain a blank cell, you should use the ISBLANK function to test for a zero value, as in the following example: =IF(ISBLANK(B2),"blank",IF(B2=0,"zero","other")) Note that the above formula returns "zero" if there is a zero value in the cell, "blank" if the cell is blank, and "other" if anything else is in the cell.
You must always use the ISBLANK formula first before you test for a zero value. Otherwise you will always return a "true" for the zero value, and never get to the test for the ISBLANK formula.

Answer: Although the Moon appears to shine, it does not emit light. Instead, we can see the Moon because it is lit up by the Sun.
Explanation:
The part of the Moon that is both sunlit and facing Earth is called the Moon's phase.
As the Moon orbits Earth, the Moon's phase changes. The model below shows the Moon's phase at eight positions in its orbit. The smaller moons closer to Earth show where sunlight hits the Moon. The larger moons farther from Earth show how the Moon will look during that phase.
