How do plants weather rocks?

• when roots grow into cracks of rocks and expand the rock
• when the plant moves water from the roots to the leaves

This rock may chemically weather easily because is has many spaces or holes in it that allow water to seep through it, meaning it is:

• permeable
• abrasive
• erosion
• unchangable
