Question: Give one positive effect and one negative effect of volcanic eruptions?

Volcanic eruptions can have both positive and negative impacts on the environment and human society. Here are one positive effect and one negative effect of volcanic eruptions:-

Positive effect:-

Fertile soil: Volcanic eruptions can create fertile soil for agriculture, as the ash and rock fragments from the eruption can enrich the soil with nutrients. In some areas, such as the islands of Hawaii, the volcanic soil has made it possible to grow crops that would not be possible otherwise.

Negative effect:-

Destruction of property and loss of life: One of the most serious negative impacts of volcanic eruptions is the destruction of property and loss of life. Lava flows, ash clouds, and pyroclastic flows can all cause significant damage to nearby communities and infrastructure, and can also pose a serious threat to human life. In addition, ash clouds can disrupt air traffic and have a major impact on local economies.
