Wind, Rain (acidic rain especially), heating and cooling, biological weathering

Explanation:

Heating and cooling causes the material to expand and contract receptively. Over time this can lead to massive damage.

Water can get into cracks, freeze into ice (and thus expand) and crack open holes in things.

Waves, Rivers and Waterfalls often cause massive erosion.

Biological weather - trees growing roots into cliff sides, weeds in pavement and ivy up the side of old brick houses are all classic examples of weathering
