Asked by .

Mt. Pinatubo, a volcano in the Philippines, erupted in 1991. The eruption resulted in the cooling of Earth’s surface for two years.

What can you deduce from the information given?

Solar energy seeped through the atmosphere.
The eruption caused sunspot activity to increase.
The volcano released a lot of sulfur dioxide and ash.
Greenhouse gases caused the cooling of Earth’s surface.

You can deduce: The volcano released a lot of sulfur dioxide and ash.

Reason: Large explosive eruptions inject SO2 and ash into the stratosphere; the SO2 forms sulfate aerosols that reflect incoming sunlight, reducing surface solar heating and causing temporary global cooling (as happened after Pinatubo). The other statements are incorrect or unrelated: aerosols reduced, not increased, sunlight; sunspot activity is unrelated to volcanic eruptions; and greenhouse gases produce warming, not the observed short-term cooling.
