Which outcome occurs when seasonal subtropical high-pressure systems weaken?

💡 Explanation

Increased seasonal stream capture results, driven by avulsion, because decreased pressure allows more localized intense rainfall; therefore, channels erode surrounding topography, rather than promoting sorted, graded sediment like constant pressure gradients typically would.
