The different spheres of Earth interact in various ways. Volcanic eruptions are natural phenomena in the geosphere. They sometimes erupt, spilling out lava and dust. The lava solidifies, forming new landmasses. Volcanoes can have an effect on the atmosphere. Volcanic ash and gas can also pollute the atmosphere, resulting in acid rain and other unfavorable weather patterns. When plants and animals are threatened by an eruption, their habitats may be destroyed, impacting the biosphere. These interactions between the geosphere, atmosphere, and biosphere demonstrate the interconnected nature of Earth's spheres.
