In Episode 50 "Jericho Falls", we talked about how the walls of Jericho fell. It's pretty simple once you see it...it's just hard to explain in a podcast!
So, here's a cross section of the walls. The stone retaining wall is on the bottom, and the main brick wall (that Rahab lived in/on) sitting just above...
And when the brick walls fell, it formed a ramp so that the Israelites could go "straight" into the city. (Josh. 6:5)
