Answer:
c) on the outer banks of the meander loops
Explanation:
The meandering streams form in places that have low elevation and are flat, covered with softer sediments. The stream starts as mostly straight, but as time passes it erodes one of the banks, while depositing on the opposite bank, become very curvy, snake-like in shape, thus a meandering stream. In the meandering streams, the water has the most velocity at the outer banks. This results in greater erosion of the outer banks, and this part constantly moves outwards. In the same time, the water has the least velocity at the inner bank, resulting in deposition of the material that it has been carrying with it, so this part constantly grows inwards.
Less children are being born due to increased efforts to lower the CBR (crude birth rate) and improve contraceptive methods. This results in less children being born, meaning that the older people are increasing in dependency (because there's more older people in the older generations vs the newer)
