Question

figure d is a map showing the extent across the world the particles from the eruption traveled. d. map of areas most affected by tambora plume refer to figure b and d. which of the following is an additional effect that could have occurred after the eruption of mount tambora? an increase in acid rain in sweden an increase in acid rain in indonesia increased temperatures in spain improved air quality in egypt

Explanation:

Mount Tambora's eruption releases volcanic particles (like sulfur dioxide) that form sulfuric acid in the atmosphere, leading to acid rain. Sweden is in the affected plume (from the map), so acid rain there is likely. Indonesia (near the volcano) would have immediate ash/acid rain, but the question is about "additional" effect post - eruption's particle spread. Increased temp in Spain is wrong (volcanic eruptions cool temps). Improved air quality in Egypt is wrong (particles reduce air quality). So the correct effect is increased acid rain in Sweden.

Answer:

A. An increase in acid rain in Sweden
