Just because we build retaining walls, fences, storm drains and other features, it doesn't mean that erosion will stop being a major and consistent force shaping the landscape.   I don't think they got their money's worth on there environmental impact statement, but I'm sure the real estate agent really sold them on the beautiful view.  For more local news on this home, read and watch here, for stunning images, see here.     


Questions to Ponder: Why do we build homes where we do?  How is this different across cultures (hint-Brazil)?

In the lower map, the location of the house is marked by a yellow pushpin inside the solid red square.  Some geological background--this poor house has the misfortune to apparently lie directly upon the contact between two carbonate formations (marked by the white dotted line), and to also be on the erosive edge of a bend in the river. Both factors probably contributed to the demise of this particular home, which was eventually set on fire: https://tinyurl.com/nw7mfd2

 

 

One thing to notice is how straight the cliff edge is upon which the house is built.  Knowing that, I'd have to say that if I had a house located on the straight cliff edges within the dotted red squares I've made on the map, I'd be worried.

Tide Makes Tombolo an Island

Seth Dixon's curator insight, March 25, 11:23 AM

Coastal physical geography produces some beautiful landforms such as tombolos.  A tombolo is created when sand deposits attach an island to a larger piece of land--think of it as special type of isthmus.  Mont St. Michel (picture above) is the world’s most famous example because of the iconic walled city with crowned with a striking medieval abbey.  As the tides fluctuated, the city and abbey were alternately connected or disconnected from the mainland.  However, a ‘super-tide’ that occurs once every 18.6 years wiped out the artificial causeway stranding motorists on France's most visited tourist destination (I wouldn't mind be stranded there right about now).

Many of our first experiments of creating landforms and designing a new world started in the sandbox (you can only image what I do at the beach).  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 don't happen to have a digital topographic map to superimpose on the sandbox and a GPU-based water simulation, then at least you've got this video.  Click here to learn more about this UC Davis project on the visualization of lake ecosystems.

YEC Geo's curator insight, December 7, 2014 8:15 PM

Actually a very good video.  My one quibble is with the introduction, when the narrator talks about mountain streams "carving" their gorges.  The puzzle of how small streams could possibly carve out deep bedrock canyons is an ongoing research problem, and is difficult to resolve from a gradualistic perspective.

Jason Schneider's curator insight, January 27, 12:15 AM

So pretty much, the water controls rivers rather than particles controlling the river. Also, it appears that the motion and strength of the water causes rivers to bend and form in different curves. I'd like to think of it as a ball bouncing from side to side and every time it touches the border land of a river, it expands to the opposite side. However, when the water flow is hitting the side of a river, the opposite side is not getting any force from the water flow. In that case, the side that is not getting hit by the water flow slowly moves to the side that is being by the water flow causing river curves.

Simulation of Yellowstone Supervolcano eruption shows that blast would blanket whole U.S. in ash

Simulation of Yellowstone Supervolcano eruption shows that blast would blanket whole U.S. in ash | Lorraine's Australian Geography Curriculum YR 8: Landforms and Landscapes | Scoop.it

A new simulation illustrates the explosiveness of the volcano that lurks beneath Yellowstone National Park in Wyoming.


Around 640,000 years ago, the volcano blew its top and coated North America with roughly 1,000 cubic kilometers of ash, enough to fill Lake Erie twice over. A simulation of the eruption described August 27, 2014 in Geochemistry, Geophysics, Geosystems reveals that a similar outburst today would bury Billings, Mont., in more than a meter (about 40 inches) of volcanic glass shards and pulverized rock. Even New York and Atlanta would receive dustings several millimeters thick as winds whisked ash through the darkened atmosphere for days.


Researchers used simulation software called Ash3d that forecasts ash fall by applying global wind patterns to data from historical eruptions. Ash3d churns out results several times faster than previous simulators and is the first program to incorporate the physics of how ash particles clump within a cloud.


While geologists say Yellowstone will likely never erupt again, scientists around the world use Ash3d daily to predict the potential fallout from restless volcanoes — including Bárðarbunga, the Icelandic volcano that began erupting in late August.

It's amazing to see that even though we have been on this planet for so long, there are stilll mysteries such as this. Tjis could have taken year s to solve but looking at the picture in the slides at the bottom of the article, it seems like this group of scientists knew exactly how to figure this out. this all happens becasue of geography and where these rocks are in the world that make them move around. Iis in a dried up lake pond that freezes over at night to create a layer of ice strong enough to help the rocks move around at night. This discovery took 2 whole years to figure out, but was vey much worth it in the end.

The first photographs have emerged of a newly formed volcanic island in the Pacific Ocean after three men climbed to the peak of the land mass off the coast of Tonga. Experts believe a volcano exploded underwater and then expanded until an island formed. The island is expected to erode back into the ocean in a matter of months.
