Does the Mass of Earth Increase or is it just a constant
 

The law of conservation of mass, also known as the principle of mass/matter conservation, states that the mass of an isolated system (closed to all matter and energy) will remain constant over time.

But

Mass is also not generally conserved in open systems (even if only open to heat and work), when various forms of energy are allowed into, or out of, the system .

The Earth gains mass each day, as a result of incoming debris from space. This occurs in the forms of "falling stars", or meteors, on a dark night. The actual amount of added material depends on each study, though it is estimated that 10 to the 8th power kilograms of in-falling matter accumulates every day. The seemingly large amount, however, is insignificant to the Earth's total mass. The Earth adds an estimated one quadrillionth of one percent to its weight each day.

Experience in the area
20years texhing and reserch expireience in geology,enginnering geology for graduate and undergraduate students-reserch guidance,10years field exoireience conducting field camps for geology students=Presently Assistant professor in geolog

Hope this will throw some light

So We can conclude that Mass of Earth increases
 

I think we can conclude there are processes that add mass to the earth. But, there has been no discussion of how mass is lost. Here is one such way: The Retention or Loss of Planetary Atmospheres (scroll about halfway down)

Your question requires an estimate of the net effects of losses and additions.

Hi John ,
Yes that's an important Question ,We have to consider loss also , if loss and gain balance match each other ,then we have
some steady state
