Is life possible on Mars? Geologists study the surface of both Mars and Earth by using interplanetary comparative analysis to further their understanding of the two planets. C.S Lewis‚ has a mind and imagination of his own when it comes to life on Mars‚ or as he calls it‚ Malacandra; A world where life exists‚ a world where humans can inhabit and explore this fantasy created by Lewis. Now‚ can these fantastic and unreal situations illustrated by Lewis be realistically possible today? There

(Mitchell 444). This article is important in order to further research by geologists and oceanographers‚ making this an interdisciplinary matter. It highlights the need for additional research using new technology to study the effects the ocean has on volcanoes and vice versa. New research is cited throughout this article; each study highlights an area in the Pacific Ocean. The Axial Seamount‚ off the Oregon coast‚ erupted in 2011 and again in 2015. The Chadwick study utilized hydrostatic pressure

you have highly destructive and explosive volcanoes often found along destructive plate boundaries because of increased pressure within the subduction zone. An example of this is the Philippines‚ which is situated above a destructive plate boundary and this leads to numerous and highly destructive volcanic eruptions. You also find volcanoes along constructive plate boundaries where the plates are moving apart and this is creating new lands and volcanoes as molten lava builds up‚ an example of this

The term Latin American as used here encompasses the Americas south of the United States‚ as well as the entire Caribbean. The musics of this vast area are perhaps most efficiently discussed in terms of ethnic components--European (especially Iberian)‚ Amerindian‚ African‚ and mestizo ("mixed" or acculturated). Amerindian Background During the colonial period in Latin America (16th-19th century) many Amerindian populations were decimated‚ and much traditional Amerindian musical culture was destroyed

CONSERVATIVE PLATE MARGINS (TRANSFORM FAULTS): When two plates slide past each other they create a conservative plate margin. The relative movement is horizontal‚ and classified as either sinistral (moving to the left) or dextral (moving to the right). Along these margins crust (lithosphere) is not being destroyed by subduction‚ neither is it being created. There is no melting of rock‚ and‚ therefore‚ no volcanic activity or formation of new crust. Despite the absence of volcanic activity‚ these

GLOBAL WARMING What Is Global Warming? Global warming is the warming of the earth through carbon dioxide (CO2) being pumped into the atmosphere from tailpipes and smokestacks. Then the gases trap heat like the glass in a greenhouse. This is where the term the “greenhouse effect” came from. What’s Happening Scientists say that the barrier insulating the continental ice caps is melting. “The impacts of warming temperatures in Antarctica

June 2011 plate tectonics and associated hazards Comment on the extent to which the features shown in the image support the theory of plate tectonics. To begin with we can see that many of the landmasses appear as separated jigsaw pieces with their complementary shaped coastlines. One example of this is how the North Western coastline of Africa could quite easily ‘slot into’ the North Eastern Coastline of America. This suggests that in the history of the Earth‚ these two land masses were once connected

debris). 3. Describe the differences among shield volcanoes‚ strato- volcanoes‚ and cinder cones. How are these differences explained by the composition of their lavas and other factors? Shield volcanoes form when the products of eruption have low viscosity and are weak‚ so they do not pile up but spread. They are broad‚ gentle does that resemble a solder’s shield. Cinder cones are cone shaped piles of basaltic lapilli and blocks. Strato-volcanoes are large; cone shaped and is made of interleaved
