Answer

Positive Impact

One positive impact of volcanoes is the creation of fertile soil. Volcanic ash contains minerals that contribute to soil fertility, which can support agriculture and enhance crop yields. This is particularly beneficial in volcanic regions, where farming can thrive due to the enriching properties of the ash.

Negative Impact

A significant negative impact of volcanoes is the risk to human life and infrastructure. Volcanic eruptions can lead to fatalities, injury, and damage to homes and infrastructure, causing economic losses and displacement of communities. For instance, the eruption of Mount Vesuvius in AD 79 famously buried the Roman city of Pompeii, leading to countless deaths and the loss of cultural heritage.
