    The two spheres that get affected due to volcanic eruption are Biosphere and Hydrosphere.

    Explanation:

    Impact and after effects of volcanic eruptions on biosphere:

    When volcanoes erupt, they spew out tiny particles of matter and gases like carbon dioxide which pollute the air very badly. The release of gas and ash into the atmosphere has hazardous effects on plant and animal Kingdom. Plants and crops get damaged after eruption because of which animals dependent on plants (herbivores) would die and eventually the carnivores would also die. Many animals are killed because of lava flow and toxic gases released in the atmosphere.

    Impact on Hydrosphere:

    Polluted air has an adverse effect on weather. Lava and volcanic ash through the air enters the water cycle and pollute the water of the water bodies. It would harm the marine life and many aquatic animals would die. Secondly, oceans become more acidic and warm which results in melting of glaciers and acid rain.
