Thursday, October 28, :30 – 1:30 pm Roberta Johnson, Dave Mastie, Becca Hatheway, and Parker Pennington IV National Earth Science Teachers Association Boulder, CO Activities from Across the Earth System

What is the Earth System? The atmosphere (Air) extends up from the Earth surface for several hundred kilometers. The biosphere (Life) is all living things, from single-celled bacteria to plants and animals. The geosphere (Land) includes all minerals, rocks, molten rock, sediments, and soils (Note there is life in soil as well.) The hydrosphere (Water) includes the ocean, rivers, lakes, streams, groundwater, water vapor. The cryosphere (Ice) is the frozen part of the Earth system and includes snow, glaciers, and sea ice.
