Eli5: how do earthworms move through harder pact dirt?


How is it possible something so soft can burrow through pact clay and such.

Elderberry gave a wonderful answer. I just want to point out that the word you’re looking for is “packed”.

* *6 passengers packed into a car*
* *The dirt has been packed down*

A “pact” is a formal vow, promise, or agreement between people or groups.

* *”My brother and I made a pact to always call each other on Christmas”.*
* *”The two countries agreed to a non-nuclear pact; neither would develop nukes if the other didn’t.”*
