eli5 how we can walk on dirt/moss and not crush and kill the microscopic critters in the dirt?

Question

ELI5, basically i saw a video of a someone lifting up moss and looking at it under a microscope to find a “water bear” also know as a tardigrade…how are we not crushing these things to death all the time?

Answer 1

At the microscopic scale nothing is really smooth and everything is very bumpy. Even when a microscopic critter gets hit by a microscopic part of your foot that microscopically sticks out, it just gets pushed out into a microscopic groove or a pit.
