Study Notes
Energy Sources of the Earth System
- Primary energy source for the Earth is the Sun, which influences multiple Earth spheres: atmosphere, hydrosphere, biosphere, and lithosphere.
- Almost all atmospheric energy is derived from solar radiation.
- The second energy source is the Earth's interior, specifically its core, impacting primarily the lithosphere through processes like plate tectonics.
- The Earth's interior has a secondary influence on other spheres, albeit indirectly.
Interaction of Earth Spheres
- Earth spheres continuously interact with each other, showcasing complex interdependencies.
- The hydrologic cycle (water cycle) serves as a key example of this interaction among the hydrosphere, atmosphere, and biosphere.
- Water enters the atmosphere mainly through evaporation from oceans and transpiration from plants and animals.
- Water vapor in the atmosphere condenses into clouds and can precipitate back to the Earth's surface, predominantly over oceans.
- Changes in one aspect of the hydrologic cycle can significantly affect other components within the cycle, illustrating the interconnectedness of Earth systems.
