A very think, cold, rusty metal pole up your @$$. :)
No. Abrasion is physical wearing away, as with sandpaper.
acid rain changing granite into clay minerals and quartz grains
mechanical weathering
High and low tide.
Gravity is a physical phenomenon.
yes
Mechanical weathering for example freeze-thew process or abrasion.

It is an example of mechanical or more specifically biomechanical weathering.

If you drop a rock and it breaks into pieces, then that is an act of mechanical weathering.

Freeze/thaw cycles are an example of mechanical weathering of rock.

Gravity plays a small part in mechanical weathering but temperature, weather, animals, plants, water and wind play much bigger parts.
Plants break rocks through a process called bioweathering. Plant roots can release chemicals that enhance weathering, while the physical force exerted by the roots as they grow can also help break apart rocks. Over time, this can contribute to the fragmentation of rocks into smaller pieces.
