Soon after the Earth coagulated, cooling enough to allow liquid water, lifeforms developed. The early junk evolving in the water died from time to time and their bodies washed up on to the sterile land at the waters edge. Bathtub ring.
That stuff mixes well with mineral shavings whittled off the rocks by earthquakes, flowing water, etc. This mixed crap accumulated for centuries and centuries.
An organism eventually evolved to take nutrition from this stuff. There was enough organic matter for a stationary creature to progress. Some of these organisms took advantage of the clearer light energy from the nearby star and evolved into plants. Later, non stationary organisms came out of the water. They left behind similar material to the original matter that mixed so well with mineral shavings. Plants grew their bodies with energy from the sun and reorganization of the available chemicals, then left those enlarged bodies on the surface. Animals added some also. More and more accumulated. Higher and higher, deeper and deeper. Some of it very very deep today. Some places still thin.
What are the macro ramifications of dirt creation? Changing chemical mixup of the gaseous and liquid layers. Probably a back and forth exchange among chemicals rather than a direct route to one chemical state. Consistent planet diameter over time (disregarding slight build up of space dust and chunks), or a fluffing-up of the planet diameter?
