Searching for a fast, simple and low-cost way to monitor Earth’s changing coastlines, a team of scientists, including Lamont-Doherty Observatory postdoctoral researcher and marine scientist Alessio Rovere, has found an innovative use for
Of all the minerals mined from the Earth, none is more useful than gold. Its usefulness is derived from a diversity of special properties. Gold conducts electricity, does not tarnish, is very easy to work, can be drawn into wire, can be hammered into thin sheets, alloys with many other metals, can be melted and
Do you remember the great game SimCity 2000? When you see the new video from SkyBox Imaging you will see some parallels. Skybox Skybox is one of many companies which are starting some real-time video streaming from space down to earth. But the new video they have released will blow your mind. check it out: […]The post Skybox and UrtheCast: earthstreams and the question of usage appeared first on
Question: How much soil is there on Earth to support the needs of people for food, clothing, fuel, and shelter? Answer: It’s probably less than you think. Watch this video

Olivine is the name of a group of rock-forming minerals of Earth’s crust. It is usually found in mafic and ultramafic igneous rocks. It is also found in Earth’s mantle and in some meteorites. Although it is not often used in industry, gem-quality specimens are cut into a gemstone known as
The evolutionary line from theropod dinosaurs is absolute. There is no question that this is one of the greatest stories that life on Earth has ever told us, But evolution is not linear; it’s chaotic. It’s bizarre. Along this theropod line, dinosaurs were experimenting – they were the evolutionary scientists of their time. One of
“We have demonstrated for the first time that we can use ambient noise to measure wind speeds. [...] Eventually, the method could be used to cheaply measure wind speed and direction in the atmosphere, critical information for weather forecasts, or even to study the rotation of Earth’s core.” Quoted from the University of Colorado Boulder
The impact of a large object onto the lunar surface in September, 2013 produced a flash and an afterglow that was bright enough to have been seen from Earth with the unaided eye for about eight seconds. The flash was the result of the tremendous impact speed generating enough heat to melt the target and
GeoWall is a competition for geotechnical engineering students where they build model mechanically stabilized earth retaining walls (MSE walls). The walls are then tested with a series of design loads and their score is a function of how well the wall performs under loading and how efficient their design was. The competition was held at the 2014 Geo-Congress in Atlanta which is put on by the Geo-Institute of ASCE. Students from universities all around the U.S. participated in this fantastic [...]
npr.org Scientists have used a powerful new technique to prove that some tiny crystals found in Western Australia are indeed the oldest known materials formed on Earth. READ
Have you tried this ELI? 'What am I made of; a comparison between the chemistry of the human body and the rest of the Earth'
Introduce the names and main features of the Earth’s four interacting spheres (diagram above):Discuss the following with the pupils:(1) These spheres are all made of naturally occurring chemical elements in differing combinations and proportions, but(2) the
Indonesia's Kelud volcano erupted unexpectedly a few weeks ago. Here are some before and after photos of the volcano, from Earth and
2/22/14 In Hyderabad in southern India, I gave two talks to students and research scientists at the NGRI- National Geophysical Institute of India, one of India’s major research centers in multidisciplinary areas of Earth Sciences. They have impressive laboratories and facilities. The NGRI compound is a nice respite from the busy city. We visited Fort Golconda, a
I remember the moment well. It was the first time that a live television broadcast was made back to Earth as humans circled the moon. We were at my Uncle Nate's house in Pomona, California and everyone but me had drifted out of the TV room to the merriment that was occurring around the Christmas tree. I was captivated by the images of the first Earthrise ever witnessed.Now, imagery from the Lunar Reconnaissance Orbiter (LRO) is allowing scientists to recreate the moment exactly as it occurred [...]
Oparin (Feb 18, 1894 - April 21, 1980) was a Russian biochemist who suggested (1938) that life on Earth developed through gradual chemical evolution of carbon-based molecules in a “primordial soup”, at just about the same time as the British biologist J. B. S. Haldane was independently proposing a similar theory.
As early as 1922, at a meeting of the Russian Botanical Society, he
“A team of scientists last year presented evidence of a correlation between the migration patterns of ocean salmon and the Earth’s magnetic field, suggesting it may help explain how the fish can navigate across thousands of miles of water to find their river of origin.” Quoted from the Oregon State University press
I came across this video, which very clearly explains how the Earth’s magnetic field protects us from Solar Storms. It then goes on to explain the link of these phenomena to our planet’s climate. The added bonus is that the images are very cool and I think the voice over is done by Liam Neeson….
Since the inception of this blog in 2006, its subtitle has been, “A blog about science, Christianity, and other topics.” Although this is an accurate description of what one will find here on The GeoChristian, it isn’t very catchy. So today I am introducing a new subtitle: The Earth. Christianity. They go together. Here’s what I
Rebecca Salvage is a third year PhD student in the School of Earth and Environment, University of Leeds. She is currently in Ecuador collaborating with IG-EPN. Today she writes about her first hand experience of the ongoing eruption of Tungurahua … Continue reading
