Question

1. gases from the eruption are released into the air and combine with water vapor creating acid rain that precipitates into the ocean. in addition to the sphere from question 1, which other two spheres are best represented as interacting, and what is one likely consequence? a) atmosphere & biosphere — acid rain damages plants and terrestrial animals b) atmosphere & hydrosphere — acid rain changes the chemical composition of the ocean c) hydrosphere & biosphere — acid rain blocks sunlight for photosynthetic organisms d) hydrosphere & cryosphere — acid rain freezes into glacier formations

Explanation:

The gases from the eruption enter the atmosphere and combine with water - vapor to form acid rain which then precipitates into the ocean (hydrosphere). This interaction changes the chemical composition of the ocean. Option a is about the impact on the biosphere which is not the focus here as the question is about the ocean. Option c is incorrect as acid rain doesn't block sunlight in a significant way for photosynthetic organisms in the context of this question. Option d is incorrect as the text doesn't mention any connection to the cryosphere.

Answer:

B. Atmosphere & Hydrosphere — acid rain changes the chemical composition of the ocean
