The highest energy thing we have going here is the rotation of the Earth, followed by the radiation heat deep in the Mantle.  I don't know how many atomic bombs they are, or how many seconds of the Sun, but it is huge.  Man isn't even the flea on these elephants.  The orbit of the Moon is somewhere there, and that controls the tides. For the rotation, two things leech off it - ocean

There is a lonely nondescript mountain of limestone in the barren desert east of Death Valley National Park. There is a hole at the base of the slope, the entrance to a cavern. Lurking within are prisoners, creatures that have been trapped in the cave for perhaps 20,000 years or more. They are mutants, no longer the same as their cousins who live freely just a few miles away. They are alone

To continue, in the Earth, with regard to available heat energy, the oceans are the dog, and the atmosphere is the fluff on the end of the tail.  In the atmosphere, water vapour is the dog, and carbon is maybe one hair on the tail. It not enough to merely state the energy ratios, one must also make a statement on stability and sensitivity.  If Roxie stood super still, and on high alert, then

This week’s Imaggeo on Mondays image is brought to you by Cyril Mayaud, from the University of Graz (Austria), who writes about an impressive hike and layers of cold and warm air. Thermal inversion is a meteorological phenomenon which occurs when a layer of cold air is trapped near the Earth’s surface by an overlying layer of warmer air. This can happen frequently at the boundary between mountainous and lowland regions such as in Slovenia and last for weeks, obscuring the sun from view to [...]

Today's new Earthlearningidea is 'Hotspots; modelling the movement of a plate across the globe'. Use a candle and a piece of card to model the evidence of the movement of a tectonic plate over a fixed heat source in the Earth’s mantle. This activity can be used in any lesson in a science or geography class dealing with plate tectonics. There are many more ideas for teaching this topic on

I remember very well watching the CBS Evening News 35 years ago on the first Earth Day. It was a major story, and I believe Walter Cronkite led the broadcast with it. We know a lot more about our planet now than we did then, and there have been some amazing successes in protecting our environment. We now know something that was not well understood then, and that is the

Today's new ELI addresses the common misconceptions about weathering and erosion. Textbook surveys have shown that misconceptions between weathering and erosion are common, when the scientific consensus is clear:- - Weathering is the break up and break down (physical break up and chemical breakdown) of rocks at the Earth’s surface without the removal of solid material (although material can
