Landslides are very fast. Weathering is slow.

Weathering is slower in a cold, dry climate primarily due to the reduced presence of moisture, which is essential for many weathering processes, such as chemical weathering. In cold conditions, the freeze-thaw cycles can occur, but without sufficient water, physical weathering is limited. Additionally, the lack of vegetation in dry climates means less organic activity that can contribute to weathering. Overall, these factors combine to slow down the weathering process significantly.
Landslides can accelerate weathering processes by exposing fresh rock material to weathering agents such as water, ice, and air. The rapid erosion caused by landslides can break down rocks into smaller particles, increasing surface area for weathering to occur. Additionally, landslides can lead to increased water infiltration, which can further enhance weathering processes in the affected area.
Erosion and weathering typically work over long periods of time, causing change slowly. However, with global warming and loss of native plants in many areas, erosion and weathering are happening at a more rapid rate.
Weathering is a process that breaks down rocks into smaller pieces, while landslides are the downward movement of these broken rock fragments and soil on a slope. Weathering weakens the rock and soil materials, making them more susceptible to sliding during heavy rainfall or earthquakes. So, while weathering can contribute to the conditions that lead to landslides, it is not the direct cause of landslides.
A landslide is typically formed by a combination of weathering and erosion. Weathering weakens the rock or soil on a slope, making it more susceptible to erosion from factors such as heavy rainfall or earthquakes, which can trigger the movement of material downslope.
Weathering happens slower than erosion. Weathering involves the breakdown of rocks and minerals on the Earth's surface through physical or chemical processes, which can take hundreds to thousands of years. Erosion, on the other hand, involves the transport of weathered material by natural forces like wind, water, or ice, which can happen more quickly depending on the intensity of these forces.
Chemical weathering is typically slower in areas with cold or dry climates, as these conditions slow down the chemical reactions that break down rocks. Additionally, rocks with low permeability or resistance to weathering, such as quartzite or granite, may experience slower rates of chemical weathering.

The greatest agent of erosion is water which is rare in the desert except during the brief rainy season. Therefore, water erosion in the desert is much slower than in areas with more rainfall.
Weathering and erosion rates can vary depending on factors such as climate, geology, and human activities. In some cases, weathering and erosion may have occurred slower in the distant past due to changes in environmental conditions like lower temperatures. However, there are instances where ancient geological features show signs of rapid erosion, so it is not always the case that these processes were slower in the past.
In wet climates, granite weathers more slowly than limestone because granite is a harder and more resistant rock compared to limestone. The minerals in granite are less susceptible to dissolution by water and chemical weathering processes, leading to slower weathering rates.
