Impact on Geological Processes
- Erosion and Weathering
- The scarcity of rainfall leads to slow chemical weathering.
- However, episodic rainfall can cause rapid erosion during downpours.
- This results in increased sediment transport to coastal areas.
- The scarcity of rainfall leads to slow chemical weathering.
- Karst Formation
- The limestone features on the island exhibit karst topography.
- Solubility of limestone combined with intermittent rain leads to the creation of caves and sinkholes.
- These features are continually shaped by both chemical and physical weathering processes.
- The limestone features on the island exhibit karst topography.

Biodiversity and Geological Interaction
- Habitat Formation
- The climate supports unique forms of plant life that influence soil composition.
- Endemic species like the Dragon's Blood tree thrive in specific climatic zones, stabilizing soil and landscape.
- Roots penetrate rock, contributing to physical weathering processes.
- The climate supports unique forms of plant life that influence soil composition.
- Soil and Rock Types
- Different soils formed through weathering result in varying geological formations.
- Soils vary in pH and mineral content, affecting erosion rates.
- Interaction between vegetation and soil influences sediment retention.
- Different soils formed through weathering result in varying geological formations.

Seismic Activity and Climate Effects
- Tectonic Activity
- The island sits in a tectonically active region which influences geological stability.
- Ground movements can alter local climate conditions by changing topography.
- Upheaval leads to the emergence of cliffs and plateaus that affect wind and rainfall patterns.
- The island sits in a tectonically active region which influences geological stability.
- Impact of Sea Level Changes
- Climate change leads to rising sea levels, further influencing coastal erosion.
- Saltwater intrusion affects freshwater systems and geological stability.
- The interaction between sea and land creates unique coastal landforms.
- Climate change leads to rising sea levels, further influencing coastal erosion.
