San Francisco Physical Geography Quiz: Quick Study Notes
San Francisco is renowned globally for its distinctive physical geography, a dramatic interplay of towering hills, active fault lines, and a dynamic coastline. This unique combination has shaped its iconic landscape, influencing everything from urban development to its cultural identity. From the mist-shrouded peaks to the churning Pacific waters and the underlying seismic forces, the city offers a compelling case study in natural forces at work.
Key Geographical Features
Built upon over 40 hills, San Francisco’s undulating terrain is defined by features like Mount Davidson (tallest), Twin Peaks, and Russian Hill (home to Lombard Street).
The city lies near major active seismic zones, most notably the San Andreas Fault to its west and the Hayward Fault in the East Bay, making it prone to earthquakes.
Bordered by the Pacific Ocean to the west and San Francisco Bay to the east, its coastline includes features like Ocean Beach, the Golden Gate strait, and numerous headlands.
The region’s geology is dominated by the Franciscan Complex, a mélange of sedimentary and metamorphic rocks, contributing to its diverse and often unstable ground.

- San Francisco is situated on a peninsula, bordered by the Pacific Ocean and San Francisco Bay.
- The city’s iconic hills, such as Mount Davidson and Twin Peaks, are a result of complex geological uplift and erosion.
- It sits near the active San Andreas and Hayward Faults, part of the major transform plate boundary between the Pacific and North American plates.
- The Golden Gate is a crucial natural strait connecting the bay to the ocean, defining the region’s maritime geography.
- Ocean Beach on the western edge is a significant coastal feature, subject to powerful Pacific currents and tides.
