List one example of interaction between spheres (flux). For example, the hydrosphere interacts with the geosphere by water carving out great canyons and shaping the landscape.

The interaction between atmosphere and hydrosphere is an example that showcases the interaction between the two spheres. Hydrosphere contains all the water on and under the Earth's surface while the atmosphere forms the gaseous content that envelops the Earth and supports life. Water from elements of hydrosphere - river, oceans, lakes etc evaporates due to the heat obtained from solar radiation. This water vapor rises up into the atmosphere and after reaching a particular temperature - pressure condition (depending on the elevation), condenses to form clouds. These clouds then create precipitation in the form of rain, ice or snow which again becomes a part of the hydrosphere.
