Volcanoes effect on the Lithosphere
Volcanoes have a positive and a negative affect on the lithosphere by burning plants and trees then pushing them into the soil by the lava. The plants then breakdown, giving nutrients to the soil. It also has a negative affect by actually being able to destruct structures many miles away. It can destroy some structures such as rocks, plants, and reefs.
Volcanoes are related with erosion because they help erosion and help block erosion. They help with erosion by push down material or cover the soil. This also helps block erosion by covering the soil so there soil stays where it is and helps the soil rehabilitate.
