Unit 4 Earth's Systems

The atmosphere is the layer of gases surrounding Earth, essential for weather, climate, and supporting life.

The geosphere includes all the solid parts of Earth, such as rocks, soil, and landforms.

The hydrosphere encompasses all water on Earth, including oceans, rivers, lakes, and water vapor.

The biosphere is the global sum of all ecosystems, where living organisms interact with each other and their environment.

Volcanic eruptions release gases and ash into the atmosphere, which can impact air quality and climate.

Humans releasing chemicals into the air, changing its composition.

Pond plants release oxygen into the hydrosphere, benefiting aquatic life.

Living organisms, like plants and animals, exchange moisture with water bodies through processes like respiration and perspiration.

The atmosphere is crucial for weather patterns, as it contains the air and moisture that drive weather systems.

The geosphere provides the foundation for ecosystems, influencing soil formation and land use.
