The major internal cause of slope failure is gravity.
Your question is not very clear in fact.Firstly,there are many kind of slope failure,such as landslides.Which one do you mean to?Secondly,every places have their own reason of "slope failure".Which places do you mean to? Anyway,I just share knowledge of mine to you.Hope you won't mind if the question isn't the one you want. What is the causing of landslides in Hong Kong?the causings of landslides in Hong Kong are heavy rainfall,rocks and soil materials and human activities.For detail,find in the questions I have answered.I remember I have answer one like this just in today.
The overall process is called Solifluction. If you imagine single particle (in the soil) on a gentle slope. When the water in the soil freezes, it expands and forces the particle away from the slope at right angles to the slope. When the ice then thaws gravity will cause the particle to settle back but the movement will be in a downwards direction, not in the direction it first moved. Add this movement together, repeate season after season and the particle gradually moves down slope.
The amount of soil erosion depends on length of the time quantity of land mass natural factors like wind temperature water and the hight difference of surround material. Slope is a major factor to affect this process more slope means much easier to drift the soil
the slope is very slow
Gradient is the steepness of a slope.

1. shear failure 2. rock flow 3. rock fall
Thension crack is generated by the difference in shear movement along the failure surface or slip plane. It formed in the upper slope face before the major failure surface appeared. So, the total shear resistance and thus the safety factor will reduce after this tension crack developement. However, this tension crack will stop developing when it reaches a critical depth. And, a new tension crack will develope behind that previous crack.
Slides that grow uphill by increments are called retrogressive; slides that grow downhill by increments are called progressive.

it depends...a ramp with transitions at top and bottom can be steeper than one without, because severe change in slope can cause the vehicle to bottom out.
Rosin bags are still on the back slope of every major league pitchers mound.
Landslide, slope failure, mass movement and mass wasting are all terms that could be used to describe a mudslide.
