My hypothesis:Deforestation. Rainwater washes the soil into the Basin, which forms silt. Is this true? If it is not, may you please give me the exact way how silt is formed from deforestation in the Amazon rainforest, and how silt affects mankind?
a substantial reason for deforestation interior the Amazon basin is the shown fact that many farmers interior the section use a fashion referred to as scale back and burn. They minimize down the rain wooded area and burn the section sparkling. They then farm this section until the soil is exhausted. quite of replenishing the soil, those farmers merely pass directly to a sparkling portion of the rain wooded area and start up lower back. This destroys the rain wooded area and leaves the soil in very unfavourable situation.
Yes, I agree with your hypothesis. With less trees to hold down the soil, increased erosion will occur and this eroded soil will eventually become silt and will be deposited in to the Amazon Basin
Silt is created by erosion of larger particles upstream. Deforestation is not the only cause, but areas that have been clear cut have higher erosion rates which will result in more silt downstream. But silt is a natural occurrence. The only effect that silt has on mankind that I can think of is when it builds up in shipping lanes. If it gets too deep, then larger boats cant use ports of waterways and the bottom needs to be dredged to clear the channel. It is a very expensive and time consuming task
