These images were taken from a satellite above western Brazil. Figure 1 shows a Brazilian forest in the year 2000. Figure 2 show
s the same area in 2012. The light-colored areas are bare land with few trees. The dark-colored areas are thick forests. On figure 2, choose the areas where soil erosion is likely to occur.
The amount of erosion depends on the vegetation. The rate of erosion increases if vegetation is removed, this causes the soil to crumble because bare soil offers no protection against wind and rain.
So in this case the lighter spaces, or the areas with few trees and bare land, are the areas where erosion is likely to occur.
The answer is C. Soil is considered a non-renewable resource because it takes millions of years for soil to renew itself due to the long process of soil formation hence soil is easily degraded by human activity within a human lifespan. In the picture shown, the deforestation will cause the soil to be easily eroded by elements of erosion. This will lead to desertification of the region which will result in a domino effect on the rest of the forest.
