The angle of repose is the steepest angle at which loose material will remain still without sliding downhill. This angle is a characteristic property of each material and depends on various factors like size, shape, density, and moisture content. The expression of the angle of repose can be observed in all the given choices. Talus slope and some slopes of sand dunes show the angle of repose of rock and sand particles, respectively. The angle of slopes on cinder (scoria) cones also reflects the angle of repose of volcanic material. Hence, all the options show the expression of the angle of repose.
