The Autumnal Equinox

The Autumnal Equinox | Chronique d'un pays où il ne se passe rien... ou presque ! | Scoop.it

"In the Northern Hemisphere, the fall equinox marks the first day of fall (autumn) in what we call astronomical seasons. There's also another, more common definition of when the seasons start, namely meteorological definitions, which are based on average temperatures rather that astronomical events.  Equinoxes are opposite on either side of the equator, so the autumnal (fall) equinox in the Northern Hemisphere is the spring (vernal) equinox in the Southern Hemisphere and vice versa."

If all the Ice melted: National Geographic's Interactive map on Rising Seas

If all the Ice melted: National Geographic's Interactive map on Rising Seas | Chronique d'un pays où il ne se passe rien... ou presque ! | Scoop.it

What if all the ice melted in the world? Now whether you believe global warming happens because of human activities or naturally is another debate. The questions “How would the world look if ALL the ice melted?” How much would the sea rise by? What would be the average temperature on Earth? are of interest to everyone.

Trust National Geographic not only to capture such questions in the best manner possible but also to visualize it in such geoawesome manner! Here’s the super interesting map by National Geographic “IF ALL THE ICE MELTED“!

LEONARDO WILD's curator insight, April 5, 2015 9:05 AM

Climate change is all about the "Pendulum Effect," where the extremes is what matters, not so much the median or average. The average may fluctuate some, but the real problem comes when the weather goes haywire. Too much water can be as destructive as too little water, and this doesn't only happen in time but in space as well, where regions get too much of one and too little of the other. We'll see strips of drought and strips of wetness, strips of cold and strips of heat, like bands across regions and across the planet. If he ice melts, the sea and fresh water strips in the ocean will keep the fresh water atop and it'll probably freeze in great bands in winter and provoke an extreme albedo effect cooling down the planet radically followed immediately by a potential mini ice age.

Why Do Rivers Curve?

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, 2015 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.

"California's drought just hit a new milestone: As of this week, 32.98 percent of the state is experiencing "exceptional" drought, making it the worst drought in the 14 years that the Department of Agriculture's Drought Monitor has tracked data."

The recent drought in California has only deepened and this Washington Post article shows an animated map that highlights the temporal and spatial patterns in the drought data (hint--it's not pretty).  In a related note, May 2014 was the hottest May in recorded history.     


Questions to Consider: What are some reasons (both from human and physical geography) for this severe drought? What can be done in the short-term to lessen the problem? What can be done to make California’s water situation better for the next 50 years?

As California's rain shortage continues, this may be a useful site for teachers and students to explore the drought over time.

Earth Structural Layer Cake

Earth Structural Layer Cake | Chronique d'un pays où il ne se passe rien... ou presque ! | Scoop.it

"One of their lessons [in a series involving geologic sciences] involved teaching the kids about the structure of the Earth. One of her friends came up with the idea of presenting a model of the Earth made out of cake. So my sister asked me if I could make a spherical cake with all the layers of the Earth inside it."

Courtney Burns's curator insight, December 7, 2013 7:58 PM

I think that this came out awesome! I definetly don't think that I would be able to pull something like this off. However what I found intersting about this was that it was like a cake map. Students were able to get a visual about what the earth's core is like. It visually shows them all the different layers of the earth. Just by visually seeing the cake like this will help a lot more kids to remember this lesson. Also by the baker putting the countries in their accurate locations makes this cake even that much better. They are veiwing a map and they don't even know it. I think this cake is a great tool to use to show students just how the earth is actually made up. By allowing the students to visually see it also makes it more likely for them to remember the material. Viewing maps can teach so much, which is why I think this "cake map" is an awesome way to teach and get the kids attention!

It's official: a global mass extinction is under way

It's official: a global mass extinction is under way | Chronique d'un pays où il ne se passe rien... ou presque ! | Scoop.it

"New research confirms that the next mass extinction is in progress, and we’re the cause. There’s been little doubt that humans have been severely altering the planet and reducing biodiversity, but it has been unclear how many species go extinct under normal circumstances, without human influence.

This new research clarifies the rate of 'background extinction' (the rate of extinction during the point before humans became a primary contributor to extinction). The research confirms that human activity is driving species extinct at a rate far higher than the background rate. A look at previous events suggests cause for concern. Geologists recognize five previous mass extinction events— the end of the Ordovician, Devonian, Permian, Triassic, and Cretaceous periods, meaning that we’re now in the 6th."

"Confluences occur wherever two streams come together. If the gradient is low (i.e., nearly level) and the properties of the two streams are very different, the confluences may be characterized by a dramatic visible distinction as the mixing occurs only slowly."
