Which process drives the uplift that generates fault block mountains?

💡 Explanation

When compressional forces cause crustal shortening, tectonic isostasy occurs because of the lithosphere adjusting to changes in crustal thickness, leading regional uplift along faults. Therefore, tectonic isostasy results in fault block mountains, rather than erosion, glacial rebound, or intrusion which operate through different mechanisms.

• Which outcome occurs when seasonal subtropical high-pressure systems weaken?
• Which consequence most directly results from differential erosion around coastal sea stacks?
• Which mechanism causes loess deposition next to glacial outwash?
