We've seen a world map made of each country's coins before. Here's another currency map that uses images of each country's bills...And of course I'm going to enjoy this.
Are you sure you want to delete this scoop?
For decades, south Louisiana residents have watched coastal landmarks disappear as erosion worsened and the Gulf of Mexico marched steadily inward.
Just because you've mapped a physical land feature, it doesn't mean it will stay that way forever. This is a reminder that the Earth and it's cultural and physical landscapes are constantly changing.

News 8 chief photojournalist Kevyn Fowler captured a road collapsing in Freeport, Maine during a storm.
The forces of erosion are usually slow and gradual, wearing away at landforms over the course of years. This video show the quick and dynamic factor that erosion can be...this is easily the most compelling 3-minute video about a single patch of road that I've ever seen.

Another reason why you shouldn't drive on flooded roads. Amazing how quickly this road went from looking fine to having a gaping hole in it.
Very interesting view of the forces of erosion. This would make a good addition to any science discussion that covers erosion and the forces of nature on the land.

The Iditarod Trail Sled Dog Race pushes participants to the brink on an unforgiving trek to the end of the world. And, as one writer who tracked the race by air discovers, that is exactly the point.
The Iditarod is as much about conquering the physical environment and harsh climates as any sporting event in the world. This article about this famous Alaskan race also has a unique geo-visualization component to it that is worth exploring--it has a map showing where the action takes place in the article and as the reader scrolls through the article, the map changes and it highlights the progression along the trail.

"A solar flare that occurred around 2 a.m. Thursday morning may create a spectacular display of northern lights Saturday evening. The midlevel flare had a long duration and was directed at Earth. Solar flares create auroras when radiation from the sun reaches Earth and interacts with charged protons in our atmosphere. The effects are greater at the magnetic poles and weaken as they move south from the Arctic or north of the Antarctic. In the northern hemisphere the results are called the aurora borealis, with the aurora australis being its southern counterpart. The result is a spectacular display of light and color for areas with clear enough views."
For more information and predictions, see the Alaska Geophysical Institute's website, which has plenty of experience predicting the Aurora Borealis.
It looks from this Map like Aurora will be visible from much of Ohio! -Lou
"Lake Manicouagan lies in an astrobleme in central Quebec covering an area of approximately 1206 square miles—an area half the size of Delaware. An astrobleme is a scar left on the Earth’s surface from an impact of a meteorite. Lake Manicouagan is the result of one of the largest identified asteroid or comet impacts on Earth. In the middle of the lake, on Rene-Levasseur Island, Mount Babel rises 3,123 feet into the air.
Lake Manicouagan is thought to have formed about 212 million years ago plus or minus 4 million years. This happened when an approximately 3.1 mile-diameter asteroid crashed into Earth toward the end of the Triassic period. Some scientists speculate that this impact may have been responsible for the mass extinction that wiped out more than half of all living species."
Scraped clean and weighted down for thousands of years by Pleistocene ice sheets, Akimiski Island in James Bay provides a case study of how Earth's land surfaces evolve following glaciation.

A new study using data from a pair of gravity-measuring NASA satellites finds that large parts of the arid Middle East region lost freshwater reserves rapidly during the past decade.
"[This] data show an alarming rate of decrease in total water storage in the Tigris and Euphrates river basins, which currently have the second fastest rate of groundwater storage loss on Earth, after India," said Jay Famiglietti, principal investigator of the study and a hydrologist and professor at UC Irvine. "The rate was especially striking after the 2007 drought. Meanwhile, demand for freshwater continues to rise, and the region does not coordinate its water management because of different interpretations of international laws."

This is a perfect example of geospatial technologies can lead to a better understanding of how the Earth's physical systems are changing because of human geography. Teaching geography is about showing how these systems are interconnected.
Detailed satellite images reveal the web of connections that sustain life on Earth.
"Earth From Space is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet. Produced in extensive consultation with NASA scientists, NOVA takes data from earth-observing satellites and transforms it into dazzling visual sequences, each one exposing the intricate and surprising web of forces that sustains life on earth."
This documentary shows something interesting for the physical geographer, human geographers, and geospatial technology specialists. In other words, this touches on just about all things geographic (with cool images!). The overarching theme is that so many things in this world that we wouldn't imagine are actually interconnected with excellent examples.

PULL a spring, let it go, and it will snap back into shape. Pull it further and yet further and it will go on springing back until, quite suddenly, it won't....
This is an interesting article discussing the limits that the Earth's physical systems have and the importance not exceeding any tipping point that could destabilize the planet if we "overstrech the springs."
A useful discussion on limits of the planet

Today's 100-year storm surge could be tomorrow's high tide.
This set of maps and articles help to explain why sea level rise is such an issue for many major metropolitan areas. In coastal cities with substantial economic development, much of the current coastal areas where once underwater until landfill projects filled in the bay. During storm surges (or if and when sea levels rise) these will be the first places to flood.

An initial analysis of the Mount Dixon landslide in New Zealand on Monday
There are some great images (and a post-landslide helicopter flight video) of the massive landslide that occurred Jan 21, 2013. The rockslide extends over 3 km, with an elevation change of approximately 800 meters. This is an excellent example to help students visualize mass wasting, alpine glaciation and erosion in general. While the mountain didn't explode strictly speaking, I couldn't help but love the headline "Mount Dixon explodes!"

Movie showing ground motion of four earthquakes propagating across a high density seismic array in Long Beach, California. Data was recorded by NodalSeismic,...
Seismic activity is to be expected in the Los Angeles region as the major hazard threat in the area. This area has a great number of sensors which now allows us to visualize seismic waves better than ever before. This video show 4 earthquakes (starting at 0:45, 2:20, 6:00, and 8:35). For more information on the science behind this clip, read the adptly named blog, The Trembling Earth.

1) What is a hotspot? A volcanic "hotspot" is an area in the upper mantle from which heat rises in a plume from deep in the Earth. High heat and lower pressure at the base of the mantle facilitates melting of the rock. This melt, called magma, rises through cracks to the surface and forms volcanoes. As the tectonic plate moves over the stationary hot spot, the volcanoes are rafted away and new ones form in their place.
Why are the Hawaiian Islands a linear formation if there are not plate boundaries in that region? Why are the islands seemingly arranged from largest to smallest? The answers lie in the physical geography of 'hot spots.' After this introductory video, you can learn more about the geologic life cycle of a hot spot volcanic island in this companion video.

Climate change is dramatically altering the Swiss Alps, where hundreds of bodies of water are being created by melting glaciers. Though the lakes can attract tourists and even generate electricity, local residents also fear catastrophic tidal waves.
Earth systems are inherently dynamic; however a change to system such as climate change can upset the system dramatically.

Hi guys, this is an interesting read that shows some of the positive benefits of global warming and specifically the melting glaciers in the Swiss Alps.
A resource for the topic 'Climate change'
What can we do learn of this? Will send this to my students.
"Peak season to spot rare, dazzling night skies over Canada and Alaska."
While I didn't get to personally witness this phenomenon over the weekend, many farther north took some incredibly images. This ABC video nicely summarizes the Aurora Borealis.
I was disappointed here in DE just because of the rarity of even the possibility of seeing the event. It was fun looking anyway and the night sky was, as always, a little mindblowiing!
Climographs chart the monthly temperature and rainfall data and are a useful tool is studying climatology. Here are links to dozens of selected United States and International cities that come from the National Drought Mitigation Center. The image above is a climograph of Providence, RI.

Video of a sandbox equipped with a Kinect 3D camera and a projector to project a real-time colored topographic map with contour lines onto the sand surface. ...
Many of our first experiments of creating landforms and designing a new world started in the sandbox. This video shows how that early childhood activity can make for an excellent classroom demonstration to shows how Earth's physical systems work. If you happen to have a digital topographic map to superimpose on the sandbox and a GPU-based water simulation, then you've got this fantastic video.

Given the recent meteor in Russia, interest has been high on the subject. Have you every wanted to simulate a the impact of a meteorite? Then this is just what you've always wanted. If you would rather to see an incredibly entertaining clip from the Daily Show, then knock yourself out (disclaimer: it's a VERY irreverant look at the the dash-cam footage from Russia that many just discovered after the meteor hit last week).
¡¡Realmente, acongoja un poquito!!
Many of you have seen the YouTube video of the meteor in Russia this week (and were you wondering why so many Russians have cameras on their dashboards?). This show the geologic impact of the largest of meteors and here are links to a map (with the data) of all the known meteorites to have landed. Pictured above is Meteor Crater in Arizona, one of the most powerful impacts the Earth has even seen.
Did you know that in 2000 the IHO created a new ocean called the Southern Ocean? Here, learn about where and what the Southern Ocean is.
Maybe if more of the global population lived in the Southern Hemisphere, perhaps our educational systems would emphasize more information about the Southern Ocean (not to mention acknowledge that it even exists). This body of water isn't just the southernmost part of the Pacific, Indian and Atlantic Oceans; the biology, temperature, chemistry and ocean currents all make it a distinct body of water that circles Antarctica. This is just one of over twenty videos in the "geography" tab from the great folks at about.com.

Every 12 years, the Kumbh Mela, a centuries-old Hindu pilgrimage, temporarily transforms an empty floodplain in India into one of the biggest cities in the world.
Hindu pilgrims from all over India flock to bathe where it the Yamuna Saraswati Rivers join with the Ganges River for a religious experience. This is a massive undertaking where the cultural practices create migratory patterns that reshape cities because of a sacred physical geography.

Pictured above is Lake Hillier, located on a small island south of Western Australia. Around the world there are many pink lakes; most of them can attribute their hue to their high salinity composition. Some algaes that thrive in salt water produce organic pigments with a reddish/pinkish coloration. This particular lake's coloration is a mystery. If you any additional information, feel free to share in in the comments section below.
