Yes, a young river typically erodes more than an old river because young rivers have a steeper gradient, higher energy, and are still shaping their course. Over time, old rivers tend to have a more established path with reduced erosional power.
A young river valley typically has a V-shape profile, with steep sides and a narrow channel. This shape is formed through the erosive action of the flowing water cutting down into the landscape. Over time, the valley may widen and deepen as the river continues to erode the surrounding rock or sediment.
Young soil is soil that has had little time to develop fully, often characterized by a lack of distinct soil horizons and a relatively high proportion of organic matter. Young soils typically have a simpler structure compared to older soils and may be more susceptible to erosion and nutrient leaching.
A mature river erodes its channel wider rather than deeper. The gradient of a mature river is less steep than young rivers, and the water flows more smoothly. Examples of mature rivers are the Thames, Mississippi, and Ohio rivers.
A river stage with high flow velocity and volume, such as during flood events, typically causes the greatest amount of erosion. The force of the water carrying sediment and debris can lead to significant erosion of riverbanks and the riverbed.
No.
No. Older rivers which meander and create oxbows are the norm. Young rivers tend to flow in straighter lines.

True
If the river is young it is steep in places and doesn't meander (curve). A mature river isn't so steep and it is starting to form meanders; but be careful because old rivers are completely flat and do have meanders.
young river
An old river is a river with a low gradient and low erosive energy. Old rivers are characterized by flood plains.
