Earth's Systems

Earth's systems refer to the interactions and interconnectedness of the various components of the Earth, including the geosphere, hydrosphere, atmosphere, and biosphere. Understanding these systems is crucial for comprehending the Earth's processes and how they impact the environment and living organisms.

Geosphere

The geosphere includes the solid Earth, comprising the crust, mantle, and core. It is responsible for geological processes such as the formation of rocks, mountains, and earthquakes.

Hydrosphere

The hydrosphere encompasses all water on Earth, including oceans, rivers, lakes, and groundwater. It plays a vital role in the water cycle, weather patterns, and sustaining life on Earth.

Atmosphere

The atmosphere is the layer of gases surrounding the Earth, essential for supporting life and influencing weather and climate. It is composed mainly of nitrogen, oxygen, and traces of other gases.

Biosphere

The biosphere includes all living organisms on Earth and their interactions with the other Earth systems. It examines the relationships between organisms and their environments, and the impact of human activities on the natural world.
