Worked Solution & Example Answer:Examine the impact of folding and faulting on the landscape - Leaving Cert Geography - Question Question 1 - 2007
Step 1
Folding: Refer to a Named Landform
Answer
Folding is a geological process that results in the bending of rock layers due to tectonic forces. A classic example of a folded landform is the Appalachian Mountains. The impact of folding on the landscape is profound, as it can create significant elevation changes, developing features such as ridges and valleys.
When rock layers are subjected to compressional stress, they may fold into synclines (downward folds) and anticlines (upward folds). This not only alters the surface geography but can also influence local climates by creating barriers to prevailing winds, thus forming rain shadows.
Step 2
Faulting: Refer to a Named Landform
Answer
Faulting occurs when there is a fracture in the Earth's crust along which movement has taken place. The San Andreas Fault in California is a well-known example of a faulted landform. The impact of faulting can be observed through the creation of features such as fault scarps and linear valleys.
Faulting can lead to sudden shifts in the landscape, often resulting in earthquakes that can massively reshape the terrain. The long-term effects of faulting also include the development of new landforms through the continued movement along the fault line, which may alter ecosystems and human activities in the vicinity.
