Desertification is the inability of ecosystems to fulfill their regulatory function caused by deforestation, overgrazing, and overworking the soil.
<h2>What is desertification?</h2>
Desertification is a phenomenon that implies the loss of fertile soils due to climatic variations and human activities.
- The three main causes of desertification are overgrazing, deforestation, and unsustainable agricultural practices.
- Overgrazing and deforestation destroy the protective vegetation layer that covers arid and semi-arid regions.
Therefore, we can conclude that desertification is the process of ecological degradation through which areas of land that were fertile and productive are transformed into deserts.

Explanation:
Depends on what happened in that video. I would rewatch it and write about what the video said about flooding and relate it to the river. Could be an ice jam or something else slowing the flow of water suddenly opened up. A breaking dam? Flash floods from an abundance of rain. As the amount of water in the river increases, so does the flow rate. If the amount of water suddenly increases more than the river was used to/it could hold, it will flood.
Rewatch the video and see if this relates at all :)
