What is the downhill movement?
1 adv If something or someone is moving downhill or is downhill, they are moving down a slope or are located towards the bottom of a hill.
What is it called when rocks slide down a hill?
The term landslide is a catch-all phrase that describes any geological process resulting in a downward movement from a slope of rock, soil, artificial fill, or a combination of the three under the influence of gravity.
Which type of mass movement happens very slowly?
Creep is a very slow mass movement that goes on for years or even centuries. You can't see creep happening but leaning fences and poles and broken retaining walls show where it has taken place.
What is the slowest mass movement?
The slowest type of mass movement is creep.
What is meaning of go downhill?
Deteriorate, worsen Deteriorate, worsen, as in Ever since the recession began, the business has been going downhill. The figurative use of downhill for “decline” dates from the mid-1800s.
What refers to the movement of rock?
A landslide is defined as the movement of a mass of rock, debris, or earth down a slope.
What is rock slumping?
slump, in geology, downward intermittent movement of rock debris, usually the consequence of removal of buttressing earth at the foot of a slope of unconsolidated material. It commonly involves a shear plane on which a back-tilting of the top of the slumped mass occurs.
Is a slump fast or slow?
The speed of slump varies widely, ranging from meters per second, to meters per year. Sudden slumps usually occur after earthquakes or heavy continuing rains, and can stabilize within a few hours. Most slumps develop over comparatively longer periods, taking months or years to reach stability.
What is the slowest moving example of mass wasting?
The slowest and least noticeable, but most widespread of the slow mass wasting categories is creep. Creep involves the entire hillside, and is characterized by very slow movement of soil or rock material over a period of several years.
What is the general term commonly applied to the slow to very rapid movement of rock or soil downslope?
Landslides Mass wasting – is movement in which bed rock, rock debris, or soil moves downslope in bulk, or as a mass, because of the pull of gravity. Landslides is a general term for the slow-to-very rapid descent of rock or soil. Regolith – Layer of all rocks and mineral fragments.
What is the slowest type of mass movement Why?
Creep is the slowest of all the mass movements and moves the most soil out of all the mass movements.

Is deposition fast or slow?
Remember, faster moving water causes erosion more quickly. Slower moving water erodes material more slowly. If water is moving slowly enough, the sediment being carried may settle out. This settling out, or dropping off, of sediment is deposition.
What is slumping in geography?
slump, in geology, downward intermittent movement of rock debris, usually the consequence of removal of buttressing earth at the foot of a slope of unconsolidated material. It commonly involves a shear plane on which a back-tilting of the top of the slumped mass occurs.
What is slump and creep?
Slump material moves as a whole unit, leaving behind a crescent shaped scar. Figure 2. Trees with curved trunks are often signs that the hillside is slowly creeping downhill. Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock.
What do you call a slope movement that can be classified as very slow to extremely slow?
Creep– the very slow, usually continuous movement of regolith down slope. Creep occurs on almost all slopes, but the rates vary. Evidence for creep is often seen in bent trees, offsets in roads and fences, and inclined utility poles (see figure 16.2c in your text).
Is a rock fall mass wasting?
Mass wasting is the movement of rock and soil down slope under the influence of gravity. Rock falls, slumps, and debris flows are all examples of mass wasting. Often lubricated by rainfall or agitated by seismic activity, these events may occur very rapidly and move as a flow.
What are the different types of landslides or downslope movement?
Landslides are part of a more general erosion or surficial pro- cess known as mass wasting, which is simply the downslope movement of earth or surface materials due to gravity. They are classified into four main types: fall and toppling, slides (rotational and translational), flows and creep.
What are the 5 type of mass movement?
Types of Mass Movement: Creep; Fall, Slip, Flow; Solifluction; Rock Glaciers; Slumping (Earthflow); Mudflow (lahar); Debris Flow, Debris Slide, Debris Avalanche; Rockslide; Rockfall; Debris Fall. Deposits: Collurium; Talus.
What are the 4 types of mass movement?
The four types of mass movement include landslides, slump, creep, and mudflows. Landslides occur when masses of soil and rocks move down a steep slope.
What is antonyms of downhill?
- acclivity,
- ascent,
- rise,
- upgrade,
- uphill,
- uprise.
What is the synonym of drop?
fall, come down, go down, descend, sink. plunge, plummet, dive, nosedive, tumble, pitch, slump. rise. 4'she dropped to her knees' fall, sink, collapse, descend, go down, slide, stumble, tumble.
Is erosion fast or slow?
slow Erosion occurs when natural agents, such as wind, water, or ice, transport the loosened soil and broken-down rock away. Erosion prevents earthen materials from building up in the place the materials formed. In most cases, erosion is a slow process that occurs inconspicuously over long periods of time.
What is called deposition?
Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice. Sediment can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by organic activity (e.g. as sea shells) or by evaporation.
What is known as slumping?
When the weathered materials do not move downward but sink "in situ", this is called slumping.
What is slow flowage?
It is the most widespread, slow, down-hill movement of regolith and soil under the influence of gravity. It usually occurs on gentle-to-medium gradient slopes where the weathered mantle is deep and is particularly common when it is also fine-grained.
What is the name of mass wasting that has extremely slow movement of particles and will result in tilted fence posts and curved tree trunks?
Creep– the very slow usually continuous movement of regolith down slope. Creep occurs on almost all slopes but the rates vary. Evidence for creep is often seen in bent trees offsets in roads and fences and inclined utility poles (see figure 16.2c in your text).
What is slope creep?
Slope creep is the slow, gradual downward displacement of soil, rock, and organic material. Slope creep causes lateral movement which can be observed through tilted electricity/phone poles, trees, or any object secured into or on a hillside.
What is slumping mass movement?
A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or a rock layer moves a short distance down a slope. Movement is characterized by sliding along a concave-upward or planar surface.
