## Step 1<br />The problem is asking us to identify the cause of soil exhaustion and erosion in the Amazon Rainforest. The options provided are tectonic activity, reforestation, deforestation, and sinkhole formation.<br /><br />## Step 2<br />We need to consider each option and its potential impact on the Amazon Rainforest. <br /><br />## Step 3<br />Tectonic activity refers to the movement of the Earth's crust, which can cause earthquakes and volcanic eruptions. While this can cause soil erosion, it is not the primary cause of soil exhaustion and erosion in the Amazon Rainforest.<br /><br />## Step 4<br />Reforestation is the process of replanting an area with trees. This would not cause soil exhaustion and erosion, but rather help to prevent it.<br /><br />## Step 5<br />Deforestation is the process of clearing a forest or stand of trees where the land is thereafter converted to a non-forest use. This can lead to soil exhaustion and erosion as the trees that hold the soil together are removed.<br /><br />## Step 6<br />Sinkhole formation is a geological process where the ground collapses into a hole. While this can cause soil erosion, it is not the primary cause of soil exhaustion and erosion in the Amazon Rainforest.
