Topographic Maps:
* Contour lines: As a mountain weathers, its elevation will decrease. This would be reflected in the contour lines becoming closer together as the slope steepens, or further apart as the slope becomes more gradual.
* Elevation: The overall elevation of the mountain would be lower on a newer map compared to an older one.
* Landform features: Features like peaks, ridges, and valleys may change shape or disappear altogether due to weathering. This would be depicted by changes in the contour lines and other topographic symbols.
* Drainage: Weathering can influence drainage patterns. New gullies or channels might form, leading to changes in the representation of rivers, streams, and other water bodies.
Geologic Maps:
* Rock types and formations: Weathering can expose different rock layers, revealing the underlying geology of the mountain. This would be reflected in changes to the symbols and colors representing the rock formations on the map.
* Fault lines and fractures: Weathering can accentuate fault lines and fractures, making them more prominent and easier to map.
* Soil types: Weathering plays a significant role in soil formation. Changes in the distribution and type of soil would be reflected in the map's legend and symbols.
Satellite Imagery and Aerial Photographs:
* Color and texture: Weathering can change the color and texture of the mountain's surface, which would be visible in satellite images and aerial photographs.
* Vegetation patterns: Weathering can affect vegetation patterns on the mountainside. For example, eroded areas may have sparse vegetation, while sheltered areas may have denser vegetation.
* Land cover changes: These images can depict the erosion of slopes, the formation of talus slopes, and the overall changes in the shape of the mountain.
Other Considerations:
* Time scale: The changes due to weathering may be subtle and take a long time to become noticeable on a map.
* Map scale: Larger-scale maps will show more detail and be more sensitive to the changes caused by weathering compared to smaller-scale maps.
Overall, changes due to weathering would be reflected on maps through alterations in contour lines, elevation, landform features, drainage patterns, rock types, soil types, vegetation patterns, and color and texture. However, the extent of these changes depends on the specific type of map and the time scale of the weathering process.
