A student researching volcanoes has taken the following notes:
• Volcanoes form where tectonic plates meet or over hotspots • Eruptions release lava, ash, and gases • Volcanic soil is extremely fertile for agriculture • Major eruptions can affect global climate by blocking sunlight • Indonesia has the most active volcanoes of any country
The student wants to contrast the destructive and beneficial aspects of volcanoes. Which choice most effectively uses relevant information from the notes?
Volcanoes form at tectonic plate boundaries or over hotspots in Earth's mantle.
While volcanic eruptions can devastate with lava and ash and even affect global climate, the resulting volcanic soil is extremely fertile for agriculture.
Indonesia has more active volcanoes than any other country in the world.
Major volcanic eruptions can block sunlight and affect global temperatures.
Correct Answer: B
Choice B. Contrasts destruction (lava, ash, climate) with benefit (fertile soil).
