"Venus's first settlements had been the Islands, constructed to float in the planet's upper atmosphere slightly to the north of the equator. Platforms built on rows of large metal cells filled with helium were covered with dirt and then enclosed in impermeable domes. On the surface, construction equipment guided by engineers on these Islands had erected three metallic pyramids housing gravitational...

Most earthquakes occur along fault lines, which form boundaries between two tectonic plates. As the relative speed of the plates around a fault increases, is there a corresponding increase in the number of earthquakes produced along the fault? According to this study published in the December issue of BSSA, the answer depends upon the type of tectonic boundary. On certain types of boundary, the efficiency...

The Dragon's Tales Will Baird comes up with the best links . And he a father of two! Astronomers have discovered hundreds of Jupiter-like planets in our galaxy. However, a handful of the planets found orbiting distant stars are more Earth-sized. This gives hope to astrobiologists, who think we are more likely to find life on rocky planets with liquid water. The rocky planets found so far are actually...

The third and final part of Fjordman’s history of geology and planetary science has been posted at Atlas Shrugs . Part one can be read here and part two here . Large sunspots may under certain conditions be seen by the unaided eye, but the modern study of them began around 1610 with the introduction of the telescope. Sunspots are strongly magnetic and appear darker because they are slightly cooler...

As the Earth's tectonic plates shift and grind miles below our feet, we feel the effects on the surface in the form of earthquakes and volcanic activity. As Ed Yong of Not Exactly Rocket Science and Chris Rowan of Highly Allochthonous explain, earthquakes far from tectonic plate boundaries may be aftershocks of more violent seismic events along mid-continental faults that occurred hundreds of years...

According to research undertaken by Atalay Ayele of Addis Ababa University in Ethiopia, a 500 metre long, 60 metre deep crack in the Earth’s surface in Afar, Ethiopia, opened in several days. The eruption of the Dabbahu volcano is believed to have widened a rift in the African and Arabian tectonic plates; as volcanic magma spilled [...]

Earthquakes occur within continental tectonic plates as well as at plate boundaries. Do clusters of such mid-plate events constitute zones of continuing hazard, or are they aftershocks of long-past earthquakes?

A landscape photograph by Edward Burynsky can be as frozen as it is arresting. But stare at his portraits of China's Three Gorges Dam or the Alberta tar sands , and you can almost make out Earth in motion. In his massive prints, the built and natural environments slam into each other like tectonic plates, driven by a global economy hurtling forward at full steam. Even if there's little actual oil...

FROM- American Thinker By James R. Fencil Earth operates a network of molten upwellings from deep seams in the planet's crust which act to shove tectonic plates across the seafloors where these plates bump into continental land outcroppings. There the spreading plates subduct beneath the continental rims and simultaneously thrust mountains upward from sea level. Such crustal movements continue to alter...

While infiltration of rain water into the sub-soil has decreased, pressure of population growth and industrialization has accelerated the rate of drawing underground water in excess of the rate at which the water table gets recharged by natural means....
