Question 13 (10 points) Many economic activities including farming and logging accounted for the drastic environmental transformation where farmers cleared trees to plant crops while loggers cut down large areas of woodland destroying natural forests. Ranching also transformed the landscape with overgrazing that could lead to __ a erosion b fission fusion d electrolytes

## Step 1<br />The question is asking about the environmental impact of human activities such as farming, logging, and ranching. These activities can lead to significant changes in the landscape and ecosystem.<br /><br />## Step 2<br />Option a, "erosion", refers to the process by which soil and rock are removed from the Earth's surface by wind or water flow, and then transported and deposited in other locations. This is a common consequence of deforestation and overgrazing, which can lead to soil erosion.<br /><br />## Step 3<br />Option b, "fission", is a term used in nuclear physics to describe a type of nuclear reaction where an atomic nucleus splits into two smaller nuclei, releasing a large amount of energy. This term is not related to the environmental impact of human activities.<br /><br />## Step 4<br />Option c, "fusion", is a term used in nuclear physics to describe a type of nuclear reaction where two atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy. This term is also not related to the environmental impact of human activities.<br /><br />## Step 5<br />Option d, "electrolytes", are substances that produce an electrically conducting solution when dissolved in a polar solvent, such as water. This term is not related to the environmental impact of human activities.
