The answer is B. The downhill flow of soil and rock resulting and rock
Mass movement is the movement of surface material caused by gravity ,
the downhill flow of soil is commonly known as landslide is a type of mass movement, so does the downhill flow of rock resulting from gravity ( commonly known as rockfall)
Well it depends on the country
If evaporation increases then condensation also increases so that water cycle remains balanced !
Because it does not directly affect the landform thus why it's considered as a passive agent. Those that do directly affect landforms are tectonic activities, winds, and water flow. Weather only onsets the formations.
