60-Second Good-To-Knows 1-24-11

This week’s topic: Environmental Science

The study of the earth and its environments in four large systems:

1. Atmosphere- the gaseous envelope of the planet
2. Hydrosphere- water in its many forms; oceans, rivers, lakes, ice (glaciers), water vapor
3. Lithosphere- the hard rock of the planetary body itself; more specifically the crust.
4. Biosphere- the thin film of life that lives on the surface and in the oceans
