Chemical Weathering
mechanical weathering
any of the various weathering processes that cause physical disintegration of exposed rock without any change in the chemical composition of the rock
Weathering is the alteration of rocks to more stable material from their exposure to the agents of air, water, and organic fluids. ... Mechanical weathering includes processes that fragment and disintegrate rocks into smaller pieces without changing the rock's mineral composition.
Not necessarily. Weathering rates would depend on the rock type, mineral composition, and density. These factors will determine a rock's resistance to acidic rainwater, freeze/thaw cycles, and abrasion.

Chemical weathering
mechanical weathering
Hardness, resistance to weathering, texture, mineral composition, color, and porosity.
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.

It is a mineral or a number of minerals which are part of the composition of rock.
The minerals that are in a rock will influence how quick it weathers. Strong materials will not weather as quickly as loose materials.
The breaking down of a Rock 'in situ' is known as Weathering. And when this Weathering takes place by Physical Change [ The Chemical Composition of Rock is not altered ] then it is known as 'Mechanical Weathering'.Processes:It takes place by the following mechanisms:-Thermal ExpansionFrost DisintegrationPressure ReleaseHydraulic ActionSalt Crystal GrowthBiological Weathering

Weathering and erosion would alter the shape of a rock, as would the application of stress possibly combined with high(er) temperature conditions.
