• Volcanoes erupt in the geosphere, sending ash and gases into the atmosphere and lava and ash into the biosphere.
• Hurricanes from the atmosphere sweep across the ocean or hydrosphere and onto the land or geosphere, damaging the dwellings of people in the biosphere who live along the coast.
• Human beings in the biosphere drill wells into Earth's crust in the geosphere to draw out underground water from the hydrosphere for drinking and irrigation of crops in the biosphere.
