Yes, they do. And this angle of repose will be different for different materials, the particle sizes and the moisture content.
Angle of repose is equal to angle of friction.
0 to 90

None of them.
Most loose, not compacted, sands and silts have an angle of repose, measured from the horizontal, of 35 degrees.
I'd love to have an angel of repose. I think you mean angle of repose. It will be affected by the shape of the material grains, and the amount of friction between them, as well as their surface area and shape. It can also be affected by the amount of water in a mixture.
The density of a material can influence its size of repose by affecting how closely packed the particles are. Higher density materials tend to have smaller size of repose because their particles can fit more tightly together, leading to a steeper angle of repose. Conversely, lower density materials have a larger size of repose due to their looser particle arrangement, resulting in a shallower angle of repose.
The three characteristics of a material that affect its angle of repose are particle size distribution, shape of particles, and surface roughness of particles. These factors influence how easily the particles can stack and maintain their structure at rest.
An increase in moisture content typically results in a decrease in the angle of repose of chalk. This is because moisture lubricates the particles, reducing friction between them and causing them to slide more easily past each other. As a result, the chalk particles are less able to stack compactly, leading to a lower angle of repose.
As Particle size increases the angle is repose decrease. Reason being, smaller particles have dominant cohesive and adhesive forces as compared to particle weight whereas in bigger particles gravity plays a dominant role so less repose angle.

The three main factors that affect the angle of repose are particle shape, size distribution, and surface roughness. A particle's shape influences how particles stack together, with angular particles generally forming steeper angles. Smaller particle sizes typically lead to flatter angles, while surface roughness can impact the interlocking and sliding of particles.
The angle at which loose material will not slide down a slope is called the angle of repose. It is the maximum angle at which an inclined surface formed of a particular loose material can remain stable without sliding. The angle of repose varies depending on the size, shape, and friction of the particles making up the material.
Θ = tan-1 2hdWhere:Θ = Angle of repose.h = Height of the particles pile.d = Distance from the center of the pile to the edge.
22o is the angle of repose.
22o is the angle of repose.
Angles of Repose was created in 2004.
