Arocky hill cracks after water settles and freezes. several trees on the hill tilt due to the very slow downhill movement of rock and soil. the movement occurs over a long distance. which type of mass movement does this describe?
Creep is usually defined as a mass movement process where the rock and other particles are forced to move slowly downward along a slope that is mostly covered with softer sediments and broken rock fragments. It results in the tilting of trees, poles, and gravestones.
The prime factor responsible for this type of movement is the process of frost heave, in which the water gets accumulated in the cracks and joints of the rocks and eventually freezes, thereby increases in volume and breaks the rock apart. The gravity also is important as it slowly allows these rock fragments to move along the slope of the hill. This takes place over a long distance.
Thus, the correct answer is option (A).
Just took Edge test (A) creep
Explanation: 100% (A) creep
Option (a) is the correct answer.
Mass movement is a process in which there is movement of sediment downhill.
For example, landslides, creep, mud flow etc all represents mass movement.
In creep, there is slow movement of particles down the slope. This is due to each slope covered with loose weathered material. This results in tilting of trees, poles, gravestones etc that are present into the ground on hill sides.
Thus, we can conclude out of the given options a rocky hill cracks after water settles and freezes. Several trees on the hill tilt due to the very slow downhill movement of rock and soil. The movement occurs over a long distance describes creep mass movement.
I DID IT ALREADY
This describes erosion
the answer is the first one great work
what is the question so I can understand
