Answer to Question 1

TRUE

Answer to Question 2

In June, 1991 Mt. Pinatubo erupted after over 600 years of dormancy, spewing millions of tons of ash, dust, and sulfur dioxide into the atmosphere. The sulfur dioxide rose to the stratosphere, where it formed sulfuric acid. Mt. Pinatubo's aerosols soon mixed with the airborne debris from dust storms, fires, and industrial haze as global winds swept them around the globe. Within 60 days of the explosion, the debris covered about 42 of the globe, from 20 S to 30 N. The debris increased atmospheric albedo and, for almost 2 years, the debris effected sunrises and sunsets and resulted in a small temporary lowering of average temperatures.
