I’ve been traveling around the UK, visiting lots of ancient sites, and I don’t understand how these places end up buried under so much dirt. I know that sometimes thousands of years pass between when something is abandoned and when it’s rediscovered, but how does that much dirt and debris cover things up over time? Can someone explain how this happens?

To add to what others have said, vegetation also helps to slowly build up layers on top of most places. Think of a side walk across an unmaintained yard. Within a year grass will be creeping over the sides, within 5 to 10 years depending on environment it could be fully covered in grass… now think of that process spread over 100’s or 1000’s of years.
