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.
Chemical weathering
Weathering can wear down rock over time, smoothing out rough rock formations. Since harder rocks are much more resistant to weathering than softer ones, weathering can change the shape of a rock formation as the soft rock is weathered away, leaving behind the hard rock in a potentially very different shape. Erosion has a very small effect, but could slightly change the shape as dirt and rock particles on the formations are blown or washed away.
A "metamorphic" rock.

If by form you mean the composition and structure, the forces of heat and pressure can lead to metamorphism of a rock from one type into another.
The type of weatheirng contributes to soil formation because if it is mecahnical weathering by force, then it will come out differentally than chemicalw eathering if it is by chemical composition. THere would be differences by the weathering depending on where the rock is.
