COLUMN A 7.2.1 A pattern found in areas that experienced glaciation. 7.2.2 The underlying rock is a dome like structure. 7.2.3 Occurs in areas of folded sedimentary rocks. 7.2.4 Main stream and tributaries all flow in the same direction on a steep slope. 7.2.5 Pattern found on a basin like structure 7.2.6 Tributaries join the main stream at acute angles. 7.2.7 Underlying rock structure has cracks and joints. 7.2.8 Streams converge into a low-lying area.

Glaciation has significantly shaped landscapes, leaving behind distinct features like U-shaped valleys and moraines, which are essential to understanding the Earth's geological history. These glacial remnants are key indicators of past climatic conditions and allow scientists to reconstruct ancient environments, linking climate change with geological formations over thousands of years! When it comes to river systems, the features of a stream network can tell us a lot about the underlying geology. For instance, dendritic patterns suggest a uniform rock type, while trellis patterns indicate folded or faulted bedrock. Recognizing these patterns not only aids in understanding local topography but also has practical applications in fields like ecology and urban planning, where watershed management is crucial!
