We were posing in front of the Spaceship Earth geosphere at Epcot for my thirteenth birthday.

First, the atmosphere, hydrosphere, geosphere and biosphere are linked.

Make a brightly colored geosphere or a lively whirligig.

Planets, meanwhile, are immensely complex economies of energy and matter that cycle between vast reservoirs in the oceans and atmosphere, the cryosphere, geosphere and biosphere.

The day before, Leslie said, they had begun an Earth science unit by talking about four spheres of terrestrial activity: the geosphere, the atmosphere, the biosphere, and the hydrosphere.
