Answer:
Matter and energy cycle through Earth's spheres in various ways. The Earth is composed of four main spheres, including the geosphere (land), hydrosphere (water), atmosphere (air), and biosphere (life). The matter and energy cycle through these spheres through various processes, such as the water cycle, carbon cycle, and nitrogen cycle.
For example, during the water cycle, water evaporates from the hydrosphere into the atmosphere, where it forms clouds. The water then falls back to the geosphere as precipitation, which can either be absorbed by plants in the biosphere or run off into rivers and streams, eventually returning to the hydrosphere.
Similarly, during the carbon cycle, carbon is exchanged between the atmosphere and biosphere through processes such as photosynthesis and respiration. Carbon is also stored in the geosphere as fossil fuels and minerals, which can be released into the atmosphere through activities like burning fossil fuels.
The nitrogen cycle involves the exchange of nitrogen between the atmosphere, biosphere, and geosphere. Nitrogen is converted into various forms by bacteria in the soil and in the roots of plants, which then absorb the nitrogen and use it to build proteins. Animals then consume the plants and return nitrogen to the soil through waste, which can be reused by plants.
Overall, these cycles help maintain a balance of matter and energy between Earth's spheres, which is essential for the survival of all living organisms on the planet.
