IX. Read the passage and then answer the questions below. (2ms)
There are many different natural causes leading to natural disasters, and being aware of these causes enables us to be better prepared when they do arrive. One of the most common natural disasters is flooding, which occurs when a river bursts its banks and the water spills out onto the floodplain. During wet periods, flood warnings are often forecasted because of a great deal of heavy rain. There are other risk factors for flooding that we have to mention such as steep-sided channels cause landslide, the lack of plant and woodland break the flow of water. In other words, there is little to slow the floodwater down if forests disappear.
