that would be ether sand stone or lime stone Cheers Gym_
It is generally considered to be granite, which will stand centuries of weathering.
The most important factors that determine the rate of weathering rock are the composition and fabric of the rocks and the physical and chemical environment to which the surface of the rock is exposed.
Sand
Of two rocks with the same composition, texture and porosity, there are multiple factors affecting their rate of weathering. Generally speaking, however, smaller rocks would tend to be mechanically weathered more quickly because they are more prone to transportation by the agents of erosion. This transportation by wind, water and ice exposes the smaller rock to more abrasion and fracture which quickens its rate of weathering. Chemical weathering also occurs more quickly in the smaller rock, as the rate of chemical weathering is directly related to the relationship of surface area to a rock's volume. The higher the surface area in proportion to mass, the quicker the rate of weathering; thus the smaller rock would weather faster.

The most rapid weathering occurs at the sharp edges and corners of rock.
Generally, the surface of a rock is the only part of the rock that the chemicals can get to, to do their weathering.
Weathering attacks the surface of the rock most rapidly.

The most important factors that determine the rate at which weathering occurs are the type of rock and the climate. Rainfall affects the rate of weathering.

Chemical weathering is when chemicals such as chemicals excreted from plants wear away at the earth's surface. Mechanical weathering is when natural forces wear away at the earth's surface such as rock.
