Mass movement is the movement of surface material caused by gravity down a slope. Mass movement types are soil creep, mud flow, rockfall, and landslide. The factors that influence mass movement is gravity, water, human activities, and vegetation.

MASS MOVEMENT GRADE 11 BAREKI KGOLAGANO
What is mass movement? ? Mass movement is the downhill or downward movement of soil, rocks, or debris without chemical change and influenced by gravity on a slope (Balasubramanian, 2017).
1. Different types of mass movement (Lanser, 2013) ? Landslide ? Mudflow ? Rockfall ? Soil creep
1.1 Soil Creep ? The Soil creep defines the slow mass wasting process of soil on a slope, under the influence of gravity. ? An example of slow mass movement.
1.2 Rockfall ? a type of fast-moving landslide that happens when rock or earth falls, bounces, or rolls from a cliff or down a very steep slope.
1.3 Mudflow ? a form of mass wasting involving fast-moving flow of debris that has become liquified by the addition of water (rainfall).
1.4 Landslide the movement of rock, earth, or debris down a sloped section of land.
2. Factors that influence mass movement (Koirala, 2012). ? Gravity (slope orientation) ? Vegetation ? Water ? Human activity
3. Effects of mass movement (Khanikrar, 2014). Loss of biodiversity Low quality of water Loss of fertile soil
4. Ways to minimise the effects of mass movement (Tudorgeog, 2009). Increase Increase the amount of vegetation on the slopes Stop Stop building infrastructure that weakens slopes Stop Stop building on steep slopes Use Use metal fences as a protective measure Create Create channels to control water movement
