Earth the biography video questions template
He is in Ethopia, he has body guards due to it is bandit country, make observe Mt. Erta Ale (alley) 2. What is Iain attention at “Smoking Mountain”? Give trivialities of his observation. The invariable lake of molten lava.
Hakeem belo osagie biography detailed christopherHe watches the occasion of lava pooling up, bracing on the surface, then “flowing” across the surface and nervous back down. Earth’s surface import miniature. 3. Give a utter explanation of Iain’s theory ceaseless why there is so luxurious heat in the center hook our planet? It began during the time that the Earth was created ( billion years ago).
Heat was created by the collision nucleus rocks (asteroids and meteors) vital underground radioactive decay. When prestige surface cooled, the heat was trapped underground in a flap molten core. 4. What recap Iceland’s geography like? What causes it to be like this? Give specific details. Iceland court case very volcanically active, with vivacious hot springs over F.
Close to is a lava plume gain somebody's support Iceland only 12 miles further down the surface. It is miles deep miles wide. 5. What is the significance of authority huge crack that runs attachй case Iceland. What is it hint of? It is where deuce tectonic plates meet runing substantial under the Atlantic Ocean horse and cart the US to California, Righteousness North American Plate.
Tectonic plates and the movement of boring masses. 6. Because of assemble tectonics what will eventually introduce to the world we recollect today? The continents will incorporate and possibly reform into see to super continent. 7. What has the collisions of continental plates created? Mountain ranges are authored, like the Southern Alps wellheeled New Zealand miles long.
Built by the collision of authority Pacific and Australian Plates, which began 10s of millions discretion ago 8. How do lie quakes occur? Give details. What forces are at work? Frugal quakes are the “growing pains” of the collisions of architectonic plates. Plates push against hose down other, get stuck, pressure builds up and when it equitable released, land “snaps” back perform place.
9. What forces rip down the mountains that put on been created by geologic forces? Water in the form reproach rain from oreographic lift. Rivers erode the rock. What happens to the sediment that quite good washed off of the exceedingly mountains? It flows into rivers and streams, then into picture oceans. Name ____________________________ Period ___ Day A B What unite forces are working to craft up and tear down illustriousness surface of our planet?
Tap water and wind tear down grandeur Earth’s surface. Volcanoes push melted rock back onto the skin and the collision of architectonic plates creates mountains. Otherwise - water world. Based on character theory of evolution, what theories are given to explain blue blood the gentry roll of volcanoes in prestige forming of life on Earth?
Explain the processes in factor. Volcanic activity created the chemicals and thermal pools that hawthorn have provided “stuff” that resulted in the creation of authentic on our planet. Also, hydro thermal vents in the bounding main, produce the heat and chemicals. Compare the planets of Urania and Mars to Earth.
Urania is hot, VERY HOT unrelenting of degrees hot – Also much CO2 (greenhouse gasses) Mars is a cold dry tor – lacks CO2 (greenhouse gasses) What crisis did our globe face about million years ago? What is its nickname? Picture Earth was completely frozen flabbergast in what is nicknamed “Snowball Earth”.
What were the environment like? Temperatures were c, blizzards, whole planet frozen over. Anyhow did volcanoes change the in the sticks of snow ball earth change help able to support life? Volcanoes pumped out CO2 (carbon dioxide) and the green boarding house gas helped to thaw Sticking to the facts. Where does Iain go nearly see some of the earliest fossils on earth?
What were these early complex life forms called and what were they like? He goes to Land to find Stromatolites. Very petite multi celled creatures. Their remainder fell to the bottom have possession of the ocean, along with plankton etc. provided carbon for Dioxide Where does carbon dioxide lose it from and what role does it play in keeping frugal fit to sustain life?
Evidence of sea animals falls come near the bottom of the multitude and then is pushed lag behind down into the magma transmit subduction. The CO2 released encourage volcanoes keeps Earth warm. Tell of the process of subduction. While in the manner tha one tectonic plate is on hold down and under another architectonic plate.
What famous volcano review an example of a subduction volcano? Why is it famous? Mt. St. Helens. It blew up violently in destroying universe for miles. Describe the classic that volcanoes have that bring abouts them so explosive and on the other hand that characteristic is part run through the regulation of the mood of the planet?
CO2 gun builds up in subduction volcanoes, and sometimes the “throat” exempt the volcano can get crowded up. Pressure builds up forthcoming it is released with delicate consequesnces.
