Alluvial Fans

Alluvial Fans | Teachers Toolbox | Scoop.it
When streams emerge from mountains, they often spread out and deposit sediment in a distinctive pattern known as an alluvial fan.

Via Seth Dixon
Ms. Harrington's insight:

In dry areas of interior drainage the human settlements are often clustered along the foothills of the mountains near landforms called alluvial fans. 


Alluvial fans and the agricultural patterns that people create on them, show how human settlements are highly dependent of the physical environment.

These fans are like a good Delta. People live between the mountains and the desert. Water runs down the mountains making a fan to where now a little distance away farms are produced and good vegetation.

these are the fascinating geographic anomalies. its amazing the civilizations that rise up on earth, but are totally alien to us, even in the age of instant communication.

An interesting little piece of Kazakhstan geography here. I find it fascinating that not only are these unique to deserts due to low vegetation but that they become perfect for agriculture (an irony of sorts I suppose). I also rather enjoy how the agricultural areas are spread out like a fan like the water runoff from the mountain. One key feature I didn't notice until I read it was the railroad that goes right through the fields to reach the town on the outskirts of the Alluvial fan. I am particularly curious to how many areas actually use this to make the desert a hospitable place for habitation (since it is usually a bad idea due to lack of water and food). It would also have been more interesting if the culture of the people who inhabit these places was discussed since it would likely be different in other places since they are only relying on 1 main water source. Geographically and historically I can imagine that places like this would have also been key strategic locations especially when traversing the arid areas.

Why Are States So Red and Blue?

Why Are States So Red and Blue? | Teachers Toolbox | Scoop.it
Theories about our right-wing and left-wing mind-sets don't explain why they are tied to geography.

 

While not endorsing all the cultural assumptions in the article, this is still an interesting exploration into expalining why distinct places are are politically aligned with particular parties. 

 

Questions to ponder: What portions of the author's argument do you agree (or disagree) with?  What do you see as the reasons behind the spatial distributions of "blue" and "red" in the United States?

this is a extremely interesting article on how certain portions of our country are know for voting for certain political party's during presidential elections. We have seen this political pattern all through our history, and can now almost always guess what states will be red or blue when it comes time for elections. Because this talks about political party's I have put this under political

2012 Election Cartograms

2012 Election Cartograms | Teachers Toolbox | Scoop.it

I'm sure most of you have seen the 2008 version of these fantastic maps and cartograms and they've been a go-to reference for me since the last election.  The typical red state/blue state map conceals much concerning the spatial voting patterns in the United States and fails to account for the population densities of these distributions.  That's what makes this county level voting maps and cartograms so valuable.  

 

Questions to Ponder: What new patterns can you see in the county map that you couldn't see in the state map?  What do the cartograms tell you about the United States population?

I'm really glad at how the cartographer of this map was able to properly demonstrate the way the American population voted during the 2012 presidential  election. Unlike the map that we are accustomed to seeing on television during political elections. What I appreciate about this map is how it tries to represent the way in which Americans caste their votes. While you'd be led to believe that certain states voted a particular way, this map proves otherwise. Another thing that this map does is represent the states that are widely considered to be Republican, and Democratic. States that tend to be in favor of GDP are conservative states, such as that of the south with the exception of FL, and the rest of the country being fairly liberal. Nonetheless, this is definitely and interesting and telling map of our patterns as voters.

The Geography of Swing States

The Geography of Swing States | Teachers Toolbox | Scoop.it
Right now, the conventional wisdom says that there are just nine states that might go either way on Nov.

 

Not all votes are created equally; votes in these 9 key states have a greater likelihood of impacting the actual outcome of the Presidential election.  If we assume that the other states vote as anticipated, and that each candidate has an equal opportunity in the remaining 9 states (yes, these are a major assumptions, but work with me), than President Obama has a 84% likelihood of winning in the 512 possible permuations.  Geographer Andy Baker has created a video that provides a solid non-partisan analysis of the political geography of these states (and other) states.
