What is a geomorphic hazard?
What is a geomorphic hazard?
A natural hazard originating from the Earth's crust (lithosphere), including events like volcanic eruptions, earthquakes, and landslides.
Which of the following is NOT a type of geomorphic hazard?
Which of the following is NOT a type of geomorphic hazard?
Floods are not caused by processes within the Earth's crust. They are linked to excessive rainfall or overflowing water bodies.
How do human activities affect geomorphic hazards?
How do human activities affect geomorphic hazards?
Human activities like deforestation, mining, and construction can alter the stability of slopes, increasing the risk of landslides.

Study Notes
Geomorphic Hazards
- Natural hazards pose threats that negatively affect the environment and human activities.
- Geomorphic hazards originate from the lithosphere and include volcanic eruptions, earthquakes, tsunamis, and mass movements such as landslides and avalanches.
- These hazards are influenced by human activities, increasing their impact.
- The consequences of geomorphic hazards include loss of life, destruction of infrastructure, disruption of communication lines, and humanitarian crises.
Landslides
- Landslides involve the sudden downward movement of a large mass of rock from steep slopes.
- Classified by factors such as movement type, material nature, and lubrication presence.
- Encompasses various mass movements of rock waste, soils, and ice.
Causes of Landslides
- Geological Causes: Involves weak or sensitive materials like fissured rocks that contribute to instability.
- Morphological Causes: Tectonic or volcanic uplift is significant in unstable regions; fluvial and glacial erosion also play a role.
- Human Factors: Activities like mining, irrigation projects, deforestation, excavation, and water leakages are major contributors to landslides.
