The four spheres of the Earth are the lithosphere (land), hydrosphere (water), atmosphere (air), and biOSphere (living organisms). These spheres are interconnected and interact to support life on Earth. For example, the lithosphere provides habitat for the biOSphere, the hydrosphere transports nutrients for living organisms, and the atmosphere influences weather patterns that affect all spheres. Together, they form a complex system where changes in one sphere can have ripple effects on the others.
