Types of landforms; RuwareGeneral Description: Near level rock outcrops (a.k.a. "whale's back" and "dwala"), develops where the basal surface is undulating and reffered to as the summit of the rises of the b.s. of weathering
Shape: Gently sloping and rounded or elongated hills, low-lying
Height: 2m to 5m
Summit: Gentle convex summit, which has a very smooth surface initially but weathering takes advantage of vertical and curvilinear sheet joints to cause exfoliation and block disintegration over time
Slope: Convex or rectilinear slopes, very gentle
Jointing: Might not be very jointed. However, vertical and horizontal jointing might exist and older ruwares would have sheet and curvilinear jointing on the surface
Vegetation: Absence or little
Surroundings: Deeply weathered regolith materials
