4. Your initial post should be submitted by Wednesday of this session and response comments posted by the session deadline.

Topic of Conversation:

Gravity law in the space technology applications for monitoring water resources of Earth; and 2. Tidal energy- applications for using natural resources.

After being acquainted with the article via the link   http://earthobservatory.nasa.gov/Features/GRACEGroundwater/ ,  answer the questions: 1. What is beneficial in using space technology for monitoring water resources; 2. Judging by this paper, what are the problems NASA scientists have in development of this method? 3. Can you tell if you  heard before about space research of the Earth or aerospace technology? 4. If you heard about other methods of searching a ground-water ; 5. What  do you  know about application of gravitation laws in geology, geodesy, navigation?

Comparing with other energy sources, how beneficial, reliable, and secure for the wildlife environment you find the tidal energy source? 2. Can you name any other benefits or loss we  get from tides? 3. How can you describe all pluses and minuses of 'weakening gravity' on our Earth, i.e  if  the gravity on the Earth was a little bit or much less than we have now
