Give two examples of interactions between spheres
1. The atmosphere interacts with the hydrosphere through the process of evaporation and precipitation. Water from oceans, rivers, and lakes evaporates due to heat from the sun, forming water vapor in the atmosphere. This water vapor then condenses and falls back to the Earth's surface as rain or snow, replenishing bodies of water and sustaining life.
2. The biosphere interacts with the geosphere through the process of weathering and erosion. Plants and animals in the biosphere depend on the geosphere for nutrients and minerals to survive. Weathering breaks down rocks into sediment, which can then be eroded by wind, water, or ice and transported to new locations. This sediment can provide essential nutrients for plant growth and contribute to the formation of new landforms.
