Wzniesienia Zielonogórskie consists of four mesoregions: Wzniesienia Gubińskie, Lower Bóbr valley, The Czerwieńska Upland and Wał Zielonogórski. The western border of the land is the valley of the lower Nysa Łużycka, northern – middle Odra valley, and the north-east – Kargowska Valley. In the south, the Zielonogórskie Hills border the Nowosolski Depression and the Zasiecka Valley.
During the Pleistocene glaciations, the nucleus of today's Zielonogórskie Heights was formed in the form of an elongated glacitectonic uplift, currently visible in the sculpture in the form of the Zielona Góra Embankment. It arose, as the advancing ice sheet stripped off the previously accumulated sediments and folded them, forming a long shaft. In its core there are tertiary rocks with lignite that was mined until recently. The height of the shaft at its highest point is 221 m, and the relative heights reach 100 m. When the North Polish ice sheet of the Leszno phase entered Poland, his tongue rested on the already existing Wał Zielonogórski. During the warming of the climate in the foreland of the embankment, the ice sheet began to melt. His forehead slowly disintegrated into sheets of dead ice. Water circulated in the constantly widened gaps between the blocks, depositing sand and gravel. After the ice melted, new forms appeared in the landscape – kemy. It was also enriched with moraine hills and extensive outwash plains with shallow no-outflow depressions (west of Zielona Góra).
The Bóbr river diligently destroyed the area, directing its waters towards the Odra River. Today, the 30-kilometer valley of the lower Bóbr picturesquely cuts through the Zielonogórskie Hills. The river in this section has a fairly large slope, from 72 m in Krzywaniec below Nowogród Biebrzański to 37 m at the mouth, which was used in the construction of hydroelectric power plants in Dychów and Raduszec Stary. There are also small traces of the presence of the ice sheet in Wzniesienia Zielonogórskie, fairly shallow lakes dotted around the area. The largest of them is Jańsko with an area of 1,5 km2. The smaller ones include Wełmicko and Płaszno. The lakes are surrounded by log rushes and unique communities of peat bog vegetation.
