Unit 2 Building Topography: Lab Practical on Volcanic Eruptions (1.5 points) Select the best match between the PROCESSES that create new topography and the FORMS that you are exposed to through media. This matching question all relates to volcanic features in Hawaii. 1.)Vog combines the words volcanic and smog. Vog is air pollution produced when sulfur dioxide and other gases and particulates are erupted into the atmosphere. Interactions with moisture and sunlight tends to make the vog worse. In the case of the May 2018 eruptions of Kilauea, the vog is being transported by the dominant winds. Please study this NASA data Answer: Winds (like trade winds)... 2.)
