Mass movement, also known as mass wasting or landslides, refers to the downward movement of rocks, soil, and debris on slopes or hillsides due to the force of gravity. It occurs when the force of gravity overcomes the cohesion and friction of the materials holding them in place. Mass movement can be caused by various factors such as heavy precipitation, earthquakes, volcanic activity, human activities, and the erosion of slopes by rivers or waves.
There are several types of mass movement, including:
1. Slides: Slides refer to the movement of materials in a single, unified mass along a well-defined surface. They can be further classified into different types based on the type of movement, such as rotational slides, where material moves along a curved surface, or translational slides, where material moves along a flat surface.
2. Falls: Falls occur when rocks or debris detach from a steep slope or cliff and descend through free fall. They often occur due to the weathering and erosion of the underlying rock, or the removal of support at the base of the slope.
3. Flows: Flows involve the movement of materials as a fluid-like mass. This can include debris flows, where a mixture of soil, rocks, and water moves rapidly downhill, or mudflows, which are more fluid and consist of a higher water content.
4. Creep: Creep refers to the slow, gradual movement of material downslope. It is characterized by the gradual tilting or distortion of objects on a slope, such as tilted fences or trees.
Mass movement can have significant impacts on the landscape and human activities. It can result in property damage, loss of life, altered ecosystems, and changes in drainage patterns. Understanding the causes and processes of mass movement is crucial for mitigating risks and implementing appropriate measures to prevent or minimize its consequences.

Mass movement, also known as mass wasting, refers to the downslope movement of rocks, soil, and other materials under the influence of gravity. It occurs on sloping landscapes and is primarily caused by the pull of gravity acting on the particles, as well as various triggering factors such as rainfall, earthquakes, human activities, and changes in slope stability.
To understand the concept of mass movement, you can follow these steps to gather information:
1. Start by searching for the term "mass movement" in a search engine or online encyclopedia. This will provide you with a general understanding of the topic.
2. Look for reputable sources such as scientific articles, textbooks, or governmental websites, as these sources tend to provide accurate information.
3. Read about the different types of mass movements such as landslides, rockfalls, slumps, and flows. Each type has its own characteristics and mechanisms of movement.
4. Explore the causes and factors that contribute to mass movement, including factors like slope steepness, weathering, vegetation cover, water content, and seismic activity.
5. Understand the impacts and significance of mass movement, such as the erosion of landscapes, damage to infrastructure, and the potential hazards it poses to human settlements.
6. Consider examples and case studies of mass movement events around the world, as this will provide practical context and help visualize the processes involved.
By following this approach, you will gain a comprehensive understanding of what mass movement is and how it occurs.
