Understanding the Biosphere and Earth's Systems

Next Generation Science

This educational video provides a comprehensive overview of Earth's biosphere, defining it as the global ecological system integrating all living beings and their relationships. It begins by establishing the context of Earth as a complex system made of four interacting spheres: the geosphere (land), hydrosphere (water), atmosphere (air), and biosphere (life). The video visually explores the immense diversity of life within the biosphere, ranging from microscopic bacteria and fungi to large mammals like camels and polar bears, across various extreme environments from deserts to arctic poles.
