1. Biosphere - The living organism-filled layer of the Earth that includes all living things and their interactions with the physical environment.
2. Atmosphere - The layer of gases that surround the Earth, protecting it from solar radiation, regulating temperature, and controlling weather patterns.
3. Geosphere - All of the solid matter that makes up the Earth, including rocks, minerals, and soil.
4. Hydrosphere - The world's oceans, lakes and rivers, and underground water sources that make up the planet's water cycle and support all life on the planet.
All four of these spheres are interconnected and influence one another. Changes in one sphere can affect the other three. For example, pollution in the atmosphere can lead to acid rain that impacts the hydrosphere. Changes in the Earth’s geosphere can affect the atmosphere, such as volcanic eruptions that release greenhouse gases. The biosphere relies on the other three spheres for survival as they provide resources such as air and water.
