Weathering allows for eroded material to be carried away by aeolian processes. As the eroded material settles in new locations, plant colonisation begins, eg sand dunes.

Weathering releases important minerals which decomposers further break down. Bacteria and fungi break down rock particles for future uptake by plants in the cycle.

The weathered material is a key part of decomposition. Climate directly impacts upon leaf litter to aid the decomposition process. From this nutrients are released.
