Roots of plants/ trees penetrate into the joints/ cracks of rocks widening them hence causing the rock to disintegrate.
Plants decompose/ rot forming organic/ humic acids which cause rocks to decay/disintegrate.
Mosses and lichens moisten rock surfaces facilitating chemical weathering.
Widening of crack and joints by plant roots allows water and air to enter into the rocks hence accelerating weathering.
