I do not necessarily agree with >>38821 (especially because the time frames in pic 1 are way, WAY too short), but Earth technically should expand because it is not a closed system:
Earth receives energy from the sun. Said energy is turned to matter by plants, which eventually decay and fall to the ground as detritus. Now detritus is reabsorbed by plants as nutrients, of course, but by virtue of not being a closed system, Earth gets slightly more energy than its ecosystem can "recycle", so you find yourself with a growing layer of matter, if only slowly.
Or, to put it into more blunt terms: Ever wonder why an excavation actually requires you to excavate something beyond several feet of soil? Or why geologists can determine different ages of the Earth by the depth and composition of the given sample?
Earth does expand. Slowly, mind you - it also constantly loses matter that slips out to space in the form of gases - but so long as the sun shines, earth will "grow".
