Block faulting is a geological process where large sections of the Earth's crust, known as blocks, are displaced due to tectonic forces. This movement can cause one block to rise while another sinks, creating features like valleys and mountain ranges. The boundaries of these blocks are often marked by faults, which are fractures in the Earth's surface. This process is commonly associated with tectonic plate movements, particularly at divergent and transform boundaries. Earthquakes can occur along these faults when stress builds up and is suddenly released. Block faulting plays a significant role in shaping the landscape and influencing geological formations.
