what is the downslope movement by gravity called ????

Answer 1

I think you mean mass wasting. Mass wasting, also known as mass movement or slope movement, is the geomorphic process by which soil, regolith, and rock move downslope under the force of gravity. Types of mass wasting include creep, slides, flows, topples, and falls, each with their own characteristic features, and take place over timescales from seconds to years

Answer 2

Downward movement of dry soil and rock caused by gravity (often called slides or avalanches).(Mass Wasting)!
