| The Portland, Connecticut floodplain of the Connecticut River experiencing a spring flood. |
The sixth video under the heading of Earth Systems and
Resources begins by examining the effects of dikes on major rivers in directing
flooding to more downriver areas. This
redirection potentially increases the degree of flooding at downriver
points. The video then examines the
concepts of aquifers, aquifer recharge and aquifer depletion, and discusses how
in coastal areas aquifer depletion can lead to salt water intrusion. The topic of water resources is concluded by
reviewing major global problems that water conservationists face and exploring
conservation solutions to some of these problems.
The video then shifts focus to soil resources and begins by
discussing the major categories of rocks, their methods of formation, the
chemistry of rocks and the rock cycle.
Special attention is given to the formation of coal. To conclude the video, the roles of wind and
water erosion are explored in relation to producing categories of soil
particles.
As with other videos in this series, it is available through
