Hydrosphere: The part of the earth composed of water id called the hydrosphere. Volcanoes can affect the hydrosphere through the eruption, the lava and volcanic ash could cause the air pollution also through the raining go in to the water cycle ad pollute the water as well. Also, the oceanâs water temperature will rise. 3.
Volcanoes erupt because of density and pressure. The lower density of the magma relative to the surrounding rocks causes it to rise (like air bubbles in syrup). It will rise to the surface or to a depth that is determined by the density of the magma and the weight of the rocks above it. As the magma rises, bubbles start to form from the gas dissolved in the magma. The gas bubbles exert tremendous pressure. This pressure helps to bring the magma to the surface and forces it in the air, sometimes to great heights.
