Question 1

IS THE GEOMORPHIC PROCESS
BY WHICH SOIL, SAND,
REGOLITH, AND ROCK MOVE
DOWNSLOPE TYPICALLY AS A
SOLID, CONTINUOUS OR
DISCONTINUOUS MASS,
LARGELY UNDER THE FORCE OF
GRAVITY, BUT FREQUENTLY WITH
CHARACTERISTICS OF A FLOW

Answer 1

MASS WASTING

Question 2

IS A SLOW AND LONG TERM MASS MOVEMENT. THE COMBINATION OF SMALL
MOVEMENTS OF SOIL OR ROCK IN DIFFERENT DIRECTIONS OVER TIME ARE DIRECTED BY GRAVITY
GRADUALLY DOWNSLOPE. THE STEEPER THE SLOPE, THE FASTER THE CREEP. THE CREEP MAKES TREES
AND SHRUBS CURVE TO MAINTAIN THEIR PERPENDICULARITY, AND THEY CAN TRIGGER LANDSLIDES
IF THEY LOSE THEIR ROOT FOOTING.

Answer 2

SOIL CREEPS

Question 3

ALSO CALLED A LANDSLIP, IS A SLOW OR RAPID MOVEMENT OF A LARGE MASS OF
EARTH AND ROCKS DOWN A HILL OR A MOUNTAINSIDE. LITTLE OR NO FLOWAGE OF THE
MATERIALS OCCURS ON A GIVEN SLOPE UNTIL HEAVY RAIN AND RESULTANT LUBRICATION BY THE
SAME RAINWATER FACILITATE THE MOVEMENT OF THE MATERIALS, CAUSING A LANDSLIDE TO
OCCUR.

Answer 3

LANDSLIDES

OR, MORE GENERALLY, RE-
MODELING ITS SHAPE

• SLOPE STABILIZATION
