Wonder Valley

why are radio observatories built at valleys, and not on mountains like optical observatories?

For radio observatories, there are no advantages to putting them on top of mountains and many disadvantages. An advantage to putting them below a hill line is pollution. Pollution from nearby cities in the form of radio interference and noise. Also, if you are going to suspend something from cables, you need a valley underneath to allow for the sag in the cables. Either that or very high towers.

Whenever you have enough people in an area that ideas like ‘real estate’ come up, you have the beginning of government. When there is plenty of land and you see someone’s house, you build your’s someplace else. When everyone wants to live in the same place, you start to need a way to get along. Also, rivers provide transportation for those who would prey on other people, so people who want to work for their living have to band together against those who would rather steal a living.

if there were no ocean canyons (trenches) then the sedimentation flowing down the rivers would result in ever increasing thickness of sediment deposits on the ocean floor. The river vallyes have been formed by the river eroding the earth/soil/rock away (underneath the river) over long periods of time. The river has always tried to find the easiest way down so some rive valleys are wide due to the changes in the river location at any give time.

but when scientists were finally able to check the ocean floor they were surprised to find the oceanic "crust" to be very thin.
They figured out that the sedimentation fom the rivers was rotated back into the earth at the trenches – it’s a way for the ocean to renew itself.

the trenches are one form of the earth’s plate boundaries, "convergent boundaries", or crust eating if you like to think of it that way.

the earth rocks! it is not still for one minute, plates moving, erosion, sedimentation build up, vocanoes, shifting magnetic fields…. a spot on the earth’s equator is spinning at 1000 miles per hour

How did the geography of Greece (the “small fertile valleys”) affect nation building in this region?

I would say that the small fertile valleys created cities in the region. The cities then became city-states which are basically cities that are small countries. They are formed because the mountains isolate different cities, making them become separate countries. The numerous city-states go to war and some become powerful, such as Athens. Eventually, one becomes powerful enough to make an empire.

I don’t know if this is what you are looking for, but I hope it helps.

Shot in HD over three years, the film follows Yellowstone’s Druid wolf pack as it struggles for control of the prized Lamar Valley, and shows the interdependence of the valley’s diverse wildlife. Academy Award-winning actor F. Murray Abraham narrates. Part of the 28th season of NATURE, the Peabody and Emmy award-winning series produced by Thirteen in association with WNET.ORG for PBS.

sorry about that it metal roof
what I have is the main roof and two room off the main roof like an X with four valleys the sun hits the dark green roof and melts and freeze on the way down and really builds up at the edges of the porchs
Its a new log house and well insulated and the pitchs are 8-12 and 6-12 and the porchs come out
i hope i explain it better.

As noted above me, you have ice dams building up. One thing you can do is install heat strips. It is a wire that runs down the valley and across the area where the ice is damming up. (This would be a spring time project,,,not now). The only draw back to heat strips is the cost of the electricity when using it. Not seriously high, but it will show in the bill and you never leave heat strips running for more than 45 minutes at a time. You can check with your local building supplies stores and see if this is feasible for your home. Best of luck and I hope this can be useful.
