Question

Understanding how to recognize landslides and other styles of mass wasting is important for homeowners! An earthflow is best described as:
a. The movement of soil downslope along a planar surface of rupture
b. A non-cohesive soil flow made up of sand to boulder sized sediments that is triggered by intense rainfall or rapid snow melt
c. A cohesive soil flow made up of mostly fine grained sediments (e.g., silt, clay and sand) that is triggered by intense rainfall or rapid snow melt
d. A landslide induced by the liquefaction of sediment during an earthquake
e. a mass of rock dislodged from a steep slope that free falls, bounces or rolls downslope
f. The gradual movement of soil downslope over the course of years or even centuries
g. The rotational movement of soil downslope along a rotational surface of rupture

Answer 1

Answer:

b. A non-cohesive soil flow made up of sand to boulder sized sediments that is triggered by intense rainfall or rapid snow melt

Explanation:

Earth flow is characterized by fine grained particles which are usually in a downwards motion as a result of the impact of the forces of gravity and water sweeping through it.

It is also known as a non-cohesive soil flow made up of sand to boulder sized sediments that is triggered by intense rainfall or rapid snow melt.
