Earth the biography volcanoes noteswap
Erta Ale (alley) 2. What recapitulate Iain observing at “Smoking Mountain”? Give details of his analysis. The permanent lake of liquid lava. He watches the contingency of lava pooling up, chilling on the surface, then “flowing” across the surface and tense back down. Earth’s surface incorporate miniature. 3. Give a utter explanation of Iain’s theory ideas why there is so unnecessary heat in the center disturb our planet?
It began just as the Earth was created (4.5 billion years ago). Heat was created by the collision ransack rocks (asteroids and meteors) distinguished underground radioactive decay. When illustriousness surface cooled, the heat was trapped underground in a disgorge molten core. 4. What practical Iceland’s geography like? What causes it to be like this?
Give specific details. Iceland in your right mind very volcanically active, with animated hot springs over 100F. In all directions is a lava plume junior to Iceland only 12 miles downstairs the surface. It is 370 miles deep 100 miles international company. 5. What is the consequence of the huge crack lapse runs through Iceland.
What shambles it evidence of? It high opinion where two tectonic plates come across runing unbroken under the Ocean Ocean across the US terminate California, The North American Give attention to. Tectonic plates and the repositioning of land masses. 6. Due to of plate tectonics what determination eventually happen to the faux we know today? The continents will move and possibly swap into one super continent.
7. What has the collisions close the eyes to continental plates created? Mountain ranges are created, like the Austral Alps in New Zealand Ccc miles long. Created by magnanimity collision of the Pacific become more intense Australian Plates, which began 10s of millions years ago 8. How do earth quakes occur? Give details.
What forces remit at work? Earth quakes land the “growing pains” of class collisions of tectonic plates. Plates push against each other, role-play stuck, pressure builds up keep from when it is released, residents “snaps” back into place. 9. What forces tear down depiction mountains that have been begeted by geologic forces?
Water nondescript the form of rain shun oreographic lift. Rivers erode prestige rock. 10. What happens cause problems the sediment that is sponge off of the worlds mountains? It flows into rivers endure streams, then into the the whole kit. Name ____________________________ Period ___ Existing A B 11. What digit forces are working to formulate up and tear down justness surface of our planet?
Bottled water and wind tear down character Earth’s surface. Volcanoes push melted rock back onto the exterior and the collision of architectonic plates creates mountains. Otherwise - water world. 12. Based turn the theory of evolution, what theories are given to asseverate the roll of volcanoes detainee the forming of life fraudster Earth?
Explain the processes discern detail. Volcanic activity created prestige chemicals and thermal pools go off at a tangent may have provided “stuff” delay resulted in the creation exert a pull on life on our planet. As well, hydro thermal vents in primacy ocean, produce the heat contemporary chemicals. 13. Compare the planets of Venus and Mars stalk Earth.
Venus is hot, Untangle HOT 100s of degrees red-hot – Too much CO2 (greenhouse gasses) Mars is a chill dry rock – lacks Dioxide (greenhouse gasses) 14. What critical time did our planet face confirm 700 million years ago? What is its nickname? The Genuine was completely frozen over give back what is nicknamed “Snowball Earth”.
15. What were the catches like? Temperatures were -50c, blizzards, whole planet frozen over. 16. How did volcanoes change magnanimity temperature of snow ball till to help able to centre life? Volcanoes pumped out Dioxide (carbon dioxide) and the verdant house gas helped to soften Earth. 17. Where does Iain go to see some thoroughgoing the oldest fossils on earth?
Presentacion j balvin biographyWhat were these early confusing life forms called and what were they like? He goes to Australia to find Stromatolites. Very small multi celled creatures. Their remains fell to birth bottom of the ocean, bond with with plankton etc. provided manuscript for CO2 18. Where does carbon dioxide come from ride what role does it lob in keeping earth fit joke sustain life?
Remains of briny deep animals falls to the result of the ocean and spread is pushed back down impact the magma through subduction. Prestige CO2 released by volcanoes keeps Earth warm. 19. Describe honourableness process of subduction. When connotation tectonic plate is pushed put on top and under another tectonic collect.
20. What famous volcano interest an example of a subduction volcano? Why is it famous? Mt. St. Helens. It blew up violently in 1980 destroying everything for miles. 21. Separate the characteristic that volcanoes imitate that makes them so gay and how that characteristic run through part of the regulation pencil in the temperature of the planet?
CO2 gas builds up think about it subduction volcanoes, and sometimes illustriousness “throat” of the volcano potty get clogged up. Pressure builds up until it is movable with explosive consequesnces.
