The whole house rests on the foundation or it will sink. What does the foundation rest on? Why doesn’t the foundation sink just as easily?

Question

I get that some foundations do have sinking issues, but how does having a foundation help? If the foundation is poured and solidifies, what stops the weight of the house from immediately sinking/tilting the foundation?

Answer 1

A foundation spreads weight out more evenly… think of difference between poking a pin through a piece of paper vs. a brick through a piece of paper.
