On the west- ern side of Colombia the Andes (AN-deez) reach 18,000 feet (5,490 m). The Andes form a cordillera (kawr-duhl-YER -uh), a mountain system made up of roughly parallel ranges. Some of the Andes’ snowcapped peaks are active volcanoes. Eruptions and earthquakes shake these mountains frequently. 236 CHAPTER 10 DO NOT EDIT--Changes must be made through “File info” CorrectionKey=TX-A Caribbean South America: Physical N 60°W W E Caribbean Sea 70°W Place The region’s landscapes include 80°W S mountains, highlands, plains, and rivers. 1.

These roles range from maintaining productive coral reef ecosystems to transporting essential nutrients from the oceans to beaches and coastal dunes. Major changes have occurred in the oceans because sea turtles have been virtually eliminated from many areas of the globe. Commercial fishing, loss of nesting habitat and climate change are among the human-caused threats pushing sea turtles towards extinction.

  • Kinematic Evolution of the Gulf of Mexico and Caribbean
    Kinematic Evolution of the Gulf of Mexico and Caribbean James Pindell Tectonic Analysis, Ltd., Cokes, Barn, West Burton, West Sussex RH20 1HD, England Also: Dept. Earth Science, Rice University, Houston, Texas, USA Email: [email protected] Lorcan Kennan Tectonic Analysis, Ltd., Cokes, Barn, West Burton, West Sussex RH20 1HD, England Abstract We present a series of 14 updated tectonic reconstructions for the Gulf of Mexico and Caribbean region since the Jurassic, giving due attention to plate kinematic and palinspastic accuracy. Primary elements of the model are: 1) a re-evaluation of the Mesozoic break-up of Pangea, to better define the Proto-Caribbean passive margin elements, the geology and kinematics of the Mexican and Colombian intra-arc basins, and the nature of the early Great Caribbean Arc; 2) pre-Albian circum-Caribbean rock assemblages are reconstructed into a primitive, west-facing, Mexico-Antilles-Ecuador arc (initial roots of Great Caribbean Arc) during the early separation of North and South America; 3) the subduction zone responsible for Caribbean Cretaceous HP/LT metamorphic assemblages was initiated during an Aptian subduction polarity reversal of the early Great Arc; the reversal was triggered by a strong westward acceleration of the Americas relative to the mantle which threw the original arc into compression; 4) the same acceleration led to the Aptian-Albian onset of back-arc closure and “Sevier” orogenesis in Mexico, the western USA, and the northern Andes, making this a nearly hemispheric event which must have
