Rocks weather due to physical changes. They can also weather as a result of chemical processes. Things that can affect the rate at which a rock weathers includes weather conditions. Rocks can decompose due to wind and water. The more intense the weather conditions, the more progressive the weathering process will be.
The increase in size of a rock generally decreases the rate at which it weathers, as larger rocks have a smaller surface area-to-volume ratio. This means there is less surface area exposed to weathering agents such as water, air, and biological organisms. Consequently, larger rocks take longer to break down compared to smaller rocks, which have more surface area exposed for weathering processes. However, other factors such as rock type, environmental conditions, and the presence of fractures can also significantly influence weathering rates.
The three important factors that determine the rate at which rock weathers are climate, rock type, and topography. Climate influences weathering through temperature and precipitation patterns, with warmer and wetter conditions typically accelerating chemical weathering. Different rock types have varying resistance to weathering processes; for example, granite weathers more slowly than limestone. Lastly, topography affects drainage patterns and exposure to elements, with steep slopes potentially leading to increased physical weathering through processes like erosion.
The minerals that make up a rock determine how fast it weathers to a large extent. This is mainly true when it comes to chemical weathering.

yes and you will get everything free
The rate at which rock weathers is primarily determined by climate (temperature and precipitation), the type of rock (composition and structure), and the presence of living organisms (such as plants or bacteria) that can contribute to the weathering process.
Oxygen in the air and acids.
Sedimentary rock weathers the fastest and easiest
Depending on how tightly packed a rock's components and molecules are put together and what the composition of the rock itself is, the amount of time it takes for the rock to be effected by outside forces will vary.
The surface area of a rock has a big affect on the rate of weathering. The higher the surface area of the rock in proportion to its overall mass will result in a quicker rate of weathering of the rock.
Sedimentary rock, such as limestone, chalk, slate and sandstone.

Some factors that affect the rate of weathering are the type of rock, the altitude and the climate.
