Question

A "slippery sheet" is a potential characteristic of:

Option 1: stable soil
Option 2: dry conditions
Option 3: trench instability
Option 4: compacted material

Answer 1

Trench instability is a potential characteristic of a "slippery sheet".

Step-by-step explanation:

A "slippery sheet" is a potential characteristic of trench instability. When slope material becomes saturated with water, it can lead to a debris flow or mud flow. This slurry of rock and mud can be slippery and cause instability, resulting in the movement of soil and potential hazards.
