Which of the following shows a system maintaining equilibrium? Responses Volcanic eruptions in the geosphere send water vapor, carbon dioxide, and sulfur gases into the atmosphere. Volcanic eruptions in the geosphere send water vapor, carbon dioxide, and sulfur gases into the atmosphere. Dam building activity by beavers in a stream determines how the water in the hydrosphere flows across the land. Dam building activity by beavers in a stream determines how the water in the hydrosphere flows across the land. Wind from the atmosphere and water from the hydrosphere cause erosion and weathering in the geosphere. Wind from the atmosphere and water from the hydrosphere cause erosion and weathering in the geosphere. The atmosphere heats up the hydrosphere, evaporating the water, then deposits the water later as precipitation.
