Impossible to determine from the information given.
Precipitation and average temperature are important drivers, but erosion rate also depends on many other factors. Which landscape erodes faster will depend on things like:
- Slope steepness and length — steeper, longer slopes give faster downslope movement and greater runoff energy.
- Surface material/rock strength — unconsolidated sediment or weakly cemented rock erode much faster than hard, resistant bedrock.
- Vegetation/ground cover — dense vegetation and root networks protect soil and slow erosion; bare ground erodes quickly.
- Drainage concentration/stream power — concentrated flow in channels (high discharge and steep gradient) produces much more fluvial erosion than dispersed sheet flow.
- Fracturing/jointing in bedrock — heavily fractured rock weathers and erodes more rapidly.
- Soil thickness and cohesion — thin, noncohesive soils are removed faster.
- Human activity — land use, deforestation, roads, agriculture can greatly accelerate erosion.
- Local microclimate and freeze–thaw frequency, sediment supply, and sea/coastal processes if applicable.
If you describe the two landscapes (slope, rock/soil type, vegetation, presence of streams or human disturbance) or upload images, I can say which one would likely erode faster and why. If you want a quantitative approach, erosion models you can use include the stream power law for fluvial erosion or the USLE/RUSLE for soil erosion (A = R·K·LS·C·P).
