Lots of useful vocabulary for this module! Practice the regular flashcards and then try the multiple choice option for best results.


Earth Revealed: Groundwater from the Annenburg Media (30 minutes) -Scroll down and click on "VoD" (Video on Demand) #21 - Groundwater. It will open a new mini-window for you to view the episode. "Approximately three-quarters of Earth’s surface is covered by water. But most fresh water comes from underground. Topics of this program include aquifers, rock porosity and permeability, artesian wells, the water table, cave formation, sinkholes, and how groundwater may become contaminated."

Water Cycle
The Water Cycle (Hydrological Cycle) - a nice animation of all the parts of the water cycle. Be sure to take the quiz!
Summary of the Water Cycle - a long but very thorough summary of the water cycle from the USGS (US Geological Survey).

Icebergs ~ Everything you want to know about icebergs. A really impressive, but not overwhelming site. Lots of pictures and some videos of icebergs around the world. Be sure to watch the video of the iceberg collapsing. Do you know the difference between a "bergy bit" and a "growler"?
