Meandering Stream

Meandering Stream | Geography Education | Scoop.it

"I'm used to rivers that know what they're doing."

Seth Dixon's insight:

Even though Chris Hadfield's time on the space station is over, his twitter stream can still be a great source of images displaying the physical and human landscapes (and if you needed any more evidence that he's the coolest astronaut ever, watch his parting video singing David Bowie's Space Oddity).

  

This incredible image clearly demonstrates the fluvial processes that have creating and this and will continue to reshape this landscape.  Meander scars, oxbow lakes, channel cutoffs, floodplains and point bars are all here in this gorgeous teaching image.

hmm, looks like some river had a little to much

All rivers move. Those that have a wide, flat basin meander most. Those meanders can be even more dramatic than in this image, snaking 10's of kilometres sideways over time. Combine this action with geological upheaval and it gets even more interesting. Check out images of the Murray River in Australia from space.

Lol... the first words that went through my head were h--- (heck) yeah.  David Bowie... sung by an astronaut... okay, back to Geography. I thought that the rivers reminded me of something I thought of during the talk in class about lava rock being changed into other kinds of rocks over time, and cycling around.  I thought on a larger scale, about this universe, and I have read before that people are studying different areas of space-time fabrics, trying to find origins of the Universe, and answers to other existential questions.  I suppose that if one could trace patterns of rivers, and if one could trace patterns of rocks, to find where they came from, and why/how they came where they came, then by examining the (assumedly tattered and marked) fabrics of space and time, people would be able to determine origins of everything from the beginning of what existed before all universes, and also the origins of life forms.  I enjoyed the movie Prometheus, which was directed by Sir Ridley Scott, and I had to say that I thought that the messages found on rocks in caves, as a catalyst that lead the cast to go visit an alien world that had something to do with human origins, could be very literally taken.  If there are clues in rocks, why wouldn't there be other clues, possibly in celluar components of life forms, or space and time?  Applying the idea of studying rocks and rivers and other physical geographical pursuits to the idea of applying it on a gigantic scale greatly appeals to me.  I believe that humans will find some answers that way, but I hadn't directly realized just that until we mentioned some stuff about physical geography, and glacial forces carrying and spreading out rocks, and deposits and erosion.  After all, the Milky Way has origins, so why believe that we came from the Milky Way, rather than beyond?
