On several occasions in earths history, huge numbers of volcanoes have erupted. these eruptions have sent particles into the air that blocked sunlight to plants, possibly causing the extinction of some species. which “spheres” interacted in these situations a. exosphere; biosphere; geosphere b. geosphere; biosphere; cryosphere c. biosphere; geosphere; atmosphere d. exosphere; geosphere; atmosphere

Option (C)

Explanation:

Volcanoes are formed along a convergent plate boundary. When volcanic eruptions takes place, it emits pyroclastic materials along with various types of harmful gases that are accumulated in the atmosphere. As a result of this, the atmosphere gets block and it does not allow the sunlight to reach on the earth's surface. Due to this, a huge amount of plant species gets extinct as it becomes impossible for the plants to carry out the photosynthesis process.

Thus, this entire process takes place by interacting with the 3 spheres, namely the biosphere, atmosphere and geosphere.

Hence, the correct answer is option (C).

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.
