ELI5: How, in just 2,000 years are we finding Ancient Greek and Roman ruins buried under a foot or more of dirt and rocks?

From my understanding dirt settles and accumulates rather slowly. 2,000 years seems like such a relatively low figure for things to get buried that much. It just doesn’t make sense!

Dirt is produced and accumulated at a very slow rate but the earth and the ground is in a constant state of very slow motion and weathering which can cover stationary objects. Ash from volcanoes, landslides, organic layering such as leaves, mudslides and other phenomenon can contribute significantly.
