Final answer:
The student's question involves matching descriptions of geologic processes to their terms, which are slump, mudflow, water, and landslide. Slump is a landslide along a curved surface, mudflow is a rapid mix of mud and water, water acts as a lubricant for sediment, and landslide is a rapid, downslope movement of earth. Soil creep denotes the gradual downhill flow of soil.
Step-by-step explanation:
The student's question involves matching geologic processes with their correct descriptions. Here are the correct matches:
- a. Slump: The result of a landslide in which the material slides along a curved surface.
- b. Mudflow: Swiftly moving mixture of mud and water.
- c. Water: This acts as a lubricant between grains of sediment.
- d. Landslide: A rapid, downslope slide of earth materials.
- The slow, steady, downhill flow of loose, weathered earth materials is known as soil creep, which is not listed in the provided options.
Landslides can be triggered by a variety of factors including over-steepened slopes, saturation by water, earthquakes, volcanic activity, and excess weight. Trees play a crucial role in stabilizing slopes and helping to prevent landslides. Sedimentation patterns vary depending on environmental conditions such as water speed and the depositional area.
