That depends on what the "mass" is made of. The angle of repose depends on the material the slope is made from and the presence (amount) of water in the material.
Fs = Shear Strength/Shear Stress
A slope with a steep gradient, loose soil, and high moisture content is most likely to produce a mass movement. Such conditions weaken the slope's stability, increasing the likelihood of landslides or debris flows. Additionally, factors like vegetation loss and seismic activity can further destabilize the slope, triggering mass movements.
Yes, this is true. Creep is a very slow movement of sediment down a slope.
Parallel to the surface of the slope and opposite to the movement of an object on the slope. Parallel to the surface of the slope and up-slope, in the case of an object resting in place on the slope.

The movement of material down slope along a curved surface is called creep. It is a slow, continuous process of particle-by-particle movement typically caused by gravity and can occur on various slope angles.
A slope with a steep gradient, loose soil, and high moisture content is most likely to produce a mass movement. Such conditions weaken the slope's stability, increasing the likelihood of landslides or debris flows. Additionally, factors like vegetation loss and seismic activity can further destabilize the slope, triggering mass movements.
A steep slope with loose, unconsolidated material is more likely to produce mass movements due to the force of gravity. Higher precipitation levels and seismic activity can also increase the likelihood of mass movements on slopes.
An event that is least likely to trigger a mass movement on a slope is a gradual, sustained increase in temperature without any other contributing factors such as rainfall or seismic activity. This is because temperature alone typically does not have a direct impact on slope stability.
A talus slope is formed by the accumulation of rock fragments that have fallen off a steep rock face due to weathering and gravity. This mass movement is known as rockfall or cliff collapse.
What has likely occurred is a phenomenon known as slope creep. Slope creep is the slow, gradual movement of soil and rock downhill due to gravity. This movement can cause the telephone wires to become misaligned as the posts are shifted over time. Factors such as moisture content, slope angle, and the type of soil or rock can contribute to slope creep.
Slope and gravity influence mass movement by determining the speed and direction of the movement. A steeper slope increases the force of gravity pulling on the material, making it more likely to move downslope. Higher slopes and stronger gravitational forces can create conditions for rapid mass movements like landslides or rockfalls.
A 1 in 40 slope means that for every 40 units of horizontal distance, there is a 1 unit rise. To convert this to degrees, you can use the arctangent function. The formula to convert slope to degrees is arctan(slope) = angle in degrees. Therefore, for a 1 in 40 slope, the angle in degrees would be approximately 1.43 degrees.
Yes, this is true. Creep is a very slow movement of sediment down a slope.
No - it makes it easier - as the slope is less steep.
Parallel to the surface of the slope and opposite to the movement of an object on the slope. Parallel to the surface of the slope and up-slope, in the case of an object resting in place on the slope.
Yes, this is true. Creep is a very slow movement of sediment down a slope.
