Earth's Systems

Earth's systems refer to the interconnected systems that make up the Earth, including the geosphere, hydrosphere, atmosphere, and biosphere. These systems interact with each other and play a crucial role in shaping the planet's physical and biological processes.

Geosphere

The geosphere includes the solid Earth, consisting of the crust, mantle, and core. It encompasses the rock and mineral components of the planet and influences processes such as plate tectonics, volcanic activity, and the formation of landforms.

Hydrosphere

The hydrosphere comprises all the water on Earth, including oceans, rivers, lakes, and groundwater. It plays a vital role in shaping the Earth's surface through erosion, weathering, and deposition. The water cycle, which involves evaporation, condensation, and precipitation, is a key process within the hydrosphere.

Atmosphere

The atmosphere is the layer of gases that surrounds the Earth. It is essential for supporting life and influencing weather patterns. The atmosphere also plays a role in regulating the Earth's temperature through the greenhouse effect and other mechanisms.

Biosphere

The biosphere includes all living organisms on Earth and their interactions with the other Earth systems. It encompasses ecosystems, biodiversity, and the influence of living organisms on the physical environment.
