The phrase "area steepness" is correct and usable in written English.
It can be used in contexts related to geography, topography, or any discussion involving the incline or slope of a specific area.
Example: "The area steepness significantly affects the erosion patterns observed in the region."
Alternatives: "slope of the area" or "incline of the region".
We found that the relationship between the size of source areas and source-area steepness was described by an inverse power function, consistent with established theory, across the range of fire severity, but that the magnitude of the slope area relationship was significantly correlated with increasing fire severity.
Mr. Hong said he doubted the accuracy of a detail in the official narrative — that villagers cultivated radishes in the area — given the steepness of the mountain.
However, this part of the study area with slope steepness of more than 40° have a lower probability of a landslide.
The areas with slope steepness of more than 40° and cover a less than 4% of the area are mostly covered by bedrocks (i.e. volcanic rocks).
Our results also demonstrate that talus slopes in hyperarid areas, despite their steepness, can store sediment for long periods (~ 500 ka) and thus constitute a valuable archive.
In a recent publication, Hafezi et al [ 5] report a case of localized endothelial damage with transient stromal edema (0.75 mm × 0.75 mm) in the central deep cornea exactly below the corneal apex, corresponding to the area of the greatest steepness and corneal thinning.
Foul weather and the steepness of the area hampered rescue attempts.
Previous analyses for natural woody biomes in East Africa indicate that canopy LAI is higher within protected areas and increases with terrain steepness, a surrogate for passive forest protection as inaccessibility hampers human encroachment and degradation (Pfeifer et al. 2014).
In this way, [ 51] presented the usage of 15 distinct geometrical features that have a sufficient descriptive nature for characterizing the Minkowski functionals, such as absolute value and position of extremum points, position of the zero-crossing, steepness measures, or areas under the curves.
The reviewed literature and field investigations have identified that the most influencing factors in the study area are: Topography, lithology, soil, geomorphology, steepness of slopes, land use, and distance from road networks and drainage (Nichol and Wong 2005; Metternicht et al. 2005).
