Question

How does faulting influence the development of a drainage basin

Answer 1

• When faulting occurs across a river valley, vertical displacement of land may occur.
• When faulting occurs across a river valley,it may cause the river to disappear into the ground through a fault line.
• Faulting may lead to the formation of escarpments with springs forming at the base due to exposure of the water table.
• If rift faulting occurs in an enclosed area, a basin may be formed. When rivers flow into a the basin, a lake may be formed. This basin may become an area of inland drainage.
• Uplifting of land which follows faulting may block a river. This may cause it to reverse or change its direction of flow.
• Some rivers may end up flowing along fault lines,thus forming a fault-guided drainage pattern.
• Faulting causes depressions which may be filled with water to form rift valley lakes.
• Faulting causes fault-guided drainage pattern.
• Faulting causes oozing of water to form springs.
• Faulting causes cracks/fault lines which may cause rivers to disappear underground.
• Faulting may cause rivers to change their direction of flow/reversed drainage.
• Vertical faulting across a river may cause a waterfall.
