- 1From:Discover (Vol. 40, Issue 6)EARTH IS ACTION-PACKED. Even if there were zero life on our planet, the place would be full of birth and death, marriage, breakup and even a little dirty dancing. That's all thanks to the lithosphere, a solid layer of...
- 2From:Journal of Himalayan Earth Sciences (Vol. 51, Issue 2)Byline: Tahseenullah Khan, Waqas Javaid, Hafiz Muhammad Danial Amin, Muneeb Arshad and M.Q. Jan Abstract The Chilas Complex is a ~40 wide and 300 long composite plutonic body exposed in the central part of...
- 3From:Journal of Himalayan Earth Sciences (Vol. 51, Issue 2)Byline: Tahseenullah Khan, Waqas Javaid, Hafiz Muhammad Danial Amin and Muneeb Arshad Abstract The Chilas Complex is a ~40 wide and 300 long composite plutonic body exposed in the central part of Kohistan island...
- 4From:SuperScience (Vol. 28, Issue 1)Name: -- Date: -- In "Mission to the Mantle" (pp. 10-13), you read about a project to drill through Earth's crust to the mantle below. Earth has five layers. Each layer is made up of different materials and has...
- 5From:Tunnels & Tunnelling InternationalAndrew Crowe, engineering geologist for Halcrow evaluated the UAE's first rock driven tunnel. The Wadi Muddiq tunnel project saw a quantitative investigation, observation and evaluation of rock mass throughout...
- 6From:Maclean's (Vol. 119, Issue 19)The earth's crust is up to six kilo; metres thick and it's never been pierced by researchers drilling into it to reach the mantle below. But a new attempt, which bored more than a kilometre into the crust, has...
- 7From:Earth (Vol. 5, Issue 5)The long ridge in this image is the underwater East Pacific Rise, west of South America. The ocean floor is spreading apart here as fast as eight inches per year. As this occurs, molten rock wells up along the crest of...
- 8From:Popular Mechanics (Vol. 183, Issue 8)A deep-sea drilling expedition has struck pay dirt almost a mile below the ocean floor. Actually, it struck gabbro, a hard, black rock that forms from cooling magma deep in the Earth's crust. The expedition marked the...
- 9From:Science News (Vol. 132, Issue 24)Link between earthquakes and El Ninos? The periodic, massive climatic upheavals known as El Nino-Southern Oscillations (ENSOs) may be triggered by intense tectonic activity in the seafloor near Easter Island in the...
- 10From:Earth (Vol. 5, Issue 2)Like huge boats riding on strong ocean currents, some continents may be carried on their tectonic journeys by currents of semiviscous rock in the mantle deep below. This new explanation for how continents move is...
- 11From:UNESCO Courier (Vol. 39, Issue 7)Volcanoes VOLCANISM plays a fundamental role in the story of the Earth. The crust we live on, the water in oceans, rivers and lakes and most of the atmosphere we breathe are derived ultimately from volcanic eruptions....
- 12From:Popular Science (Vol. 275, Issue 2)AUGUST 1964 Deep Diver Alvin, the first deep-sea research vessel to carry passengers, made a splash in the summer of '64. Built to replace clunky, less-maneuverable subs, Alvin had a nimble body of titanium,...
- 13From:Science News (Vol. 130)Ancient traces of plate tectonics? One of the best places for geologists to study ancient seaflooris the mountains. When continents collide and close up ocean basins, slivers of oceanic crust, called ophiolites, are...
- 14From:Science News (Vol. 127)An oceanographic ship towing a magnometer in its wake will record a zebralike pattern of magnetic stripes from the ocean floor below. Scientists have long known that lavas coming from mid-ocean ridges where new seafloor...
- 15From:Geographical (Vol. 80, Issue 11)Traces of minerals found inside diamonds are showing scientists what is taking place hundreds of metres under the Earth's crust, according to a report published in the journal Nature. While the ocean's crust is...
- 16From:Science News (Vol. 128)Since the theory of plate tectonics was proposed 20 years ago, earth scientists have relied on geologic evidence averaged over millions of years to guess the boundaries and relative motions among the earth's dozen...
- 17From:Science News (Vol. 183, Issue 10)Bits of crust that sink into the planet's interior can last for billions of years, geologists report in the April 25 Nature. Rita Cabral of Boston University and colleagues discovered traces of ancient crust in one of...
- 18From:Science News (Vol. 187, Issue 5)Lowered sea levels during ice ages can increase the amount of magma bubbling up at mid-ocean ridges, researchers propose online February 5 in Science. The work suggests that long stretches of thick oceanic crust called...
- 19From:Science News (Vol. 128)It's been smooth sailing this year for the JOIDES Resolution and the Ocean Drilling Program (ODP). After leaving the Bahamas and Leg 101 (SN: 5/11/85, p. 294), the drillship steamed to a site 360 nautical miles north of...
- 20From:Natural History (Vol. 109, Issue 8)Few of us will ever have a chance to visit a deep-sea ridge to witness a volcanic eruption as new oceanic crust is being formed. And since I'm slightly claustrophobic myself, the thought of descending a mile or more in...
