Geological Formation

The topography of Petaling Jaya is shaped by its geological history. The area was once part of a coastal swamp, which gradually gave way to alluvial deposits from nearby rivers. The presence of these sediments contributed to the formation of the flat, fertile plains that cover most of the city. The hills and ridges are remnants of older rock formations that have been uplifted over time. The Klang River played a crucial role in sculpting the landscape, as its meandering course created floodplains and terraces that now support diverse ecosystems.
