Lecture 1b “The life cycle of Mountains”
“In nature nothing exists alone.” (Rachel Carson)
The life cycle of Mountains
Preamble:
Mountains are dynamic systems that evolve over vastly different timescales, from the slow, geological processes that build and wear down entire ranges over tens of millions of years, to the rapid, often destructive natural hazards such as landslides and earthquakes that occur over human timescales. This course explores the full life cycle of mountains—from their formation through plate tectonics and crustal deformation, to their erosion and eventual disappearance. It also addresses the feedbacks between mountain building, climate, and ecological and chemical cycles, and examines how geophysical and geomorphological hazards emerge in active mountain belts. Through this multi-scale perspective, students gain a holistic understanding of mountains as both geological and environmental systems.
Benefits from lecture:
Students have acquired basic understanding of and can explain how mountains are formed and eroded. They are able to discuss the interlinked processes of mountain building influencing climate and the carbon cycle over different timescales and can assess natural geophysical and geomorphological natural hazards inherent to active mountain ranges.
Special features of lecture:
- A Journey Through Time and Scale: Experience the evolution of mountain ranges from deep geologic time to modern-day dynamics—exploring how colossal forces shape the Earth and how those changes affect our climate, ecosystems, and societies.
- Focus on Natural Hazards in Mountain Regions: Learn how to assess and explain mountain hazards such as earthquakes, landslides, volcanic eruptions.... with real world applications... and a special focus on their occurrence in space and time
- Interdisciplinary Integration and Discussion-Based & Research-Inspired Learning: This course links geology with interdisciplinary mountain research disciplines to give students an integrative understanding of Earth's (mountain) systems.
Main lecturers:
- Michael Strasser
