Burrowing in the ground doesn't directly break rocks. It's a form of biological weathering, not mechanical weathering.

Here's why:

* Mechanical weathering involves physical forces that break down rocks. Examples include freezing/thawing, abrasion, and thermal expansion/contraction.

* Biological weathering involves living organisms breaking down rocks. Animals like burrowing creatures (worms, moles, rabbits) contribute to this by:

* Dislodging rocks: Their digging actions can loosen rocks and move them around.

* Creating pathways: Their burrows can create channels for water and air to infiltrate, which can accelerate other weathering processes.

So, while burrowing doesn't directly break rocks, it creates conditions that can lead to the breakdown of rocks over time.
