How+The+Earth+Was+Made

250 mill mantle Erupt and 95 % dies of the earth
 * 1) Geology as a profession is only about how old: Just over 200 years ago.
 * 2) Who is considered the Father of Modern Geology: Hutton.
 * 3) According to early interpretation of the Bible, the Earth is how old: 6,000 years old Oct. 24 Afternoon.
 * 4) What feature studied in "geologic time" indicated to Hutton that the Earth had to be more than 6000 years old: Rocks in Scotland the rocks were rigth angle.
 * 5) The Earth was formed by Meteors collisions with the proto-Earth.
 * 6) Lord Kelvin's age of the Earth was based upon the of a molten crust: Cooling.
 * 7) In 1911 used radioactivity to estimate an accurate age of the Earth to be how old: Aurthor Homes.
 * 8) Radioactive uranium decays to Lead.
 * 9) The accepted age of the Earth is 4.5 Billion years.
 * 10) The Barberton Hills of South Africa have that show the planet had oceans by 3.5 billion years (b.y.) ago: Pillow lava.
 * 11) Many Geologist now believe that much of the Earth's water came from Asteroids Rather then out of gassing volcanic activity.
 * 12) By 4.0 b.y. ago 90 % of the Earth was covered with water.
 * 13) The early atmosphere around 4.0 b.y. was ~200 degrees F mainly due to Carbon Dioxide.
 * 14) The nucleus of the continents appears around 3.4 b.y. and are composed of Granite.
 * 15) Superheated mixing with basalt can form Granite.
 * 16) The shallow coastal waters of the new continents 3.5 B.Y. ago hosted Earth's first life; the Stromatolites.
 * 17) The new life strips what out of the atmosphere and adds what to it?: Oxygen.
 * 18) Seas change from to due to the oxidation of iron in the water: Green to Blue.
 * 19) The world's supply of iron ore is mined from rocks called the Banded Iron Formation.
 * 20) By 1.5 B.Y. the continents cover 25 % of the Earth's surface and are moving about in a theory we call Plate Techtonics today.
 * 21) The meteorologist in 1912 proposed continental drift based upon what evidence: Vhener looks at the shap of the continents.
 * 22) Oceanic floor is continuously being Recycled.
 * 23) The island of Iceland is situated on the. Mid Atlantic Bridge
 * 24) The fissure canyons of Iceland are opening at a rate of inch/year: 1 inch.
 * 25) Plate motion can be traced back to 2.5 billion years . when Canada and the U.S form the core of the super continent called Rodinia.
 * 26) The Earth became a when the super continent blocked the redistribution of heat by ocean currents:
 * 27) Life at the time was brought to near: Snow ball Exstineion
 * 28) Rodinia was split by volcanic activity and the Earth's atmosphere was briefly warmed by
 * 29) Sea water was rich in Oxygen.
 * 30) The Bitgess Shale in the Canadian Rockies is a treasure trove of Cambrian Period fossils.
 * 31) Fossils at the beginning of the Paleozoic show the adaptation of these features not seen in earlier fossils: T eeth, Shells, Eyes, Skeletons.
 * 32) The accumulation of oxygen in the atmosphere allowed the formation of the Ozone Layer which became a shield for what radiation?: Ultraviolet.
 * 33) The first life to move ashore some 300-400 million (m.y.) ago were Plants
 * 34) The Carboniferous, part of which is the Pennsylvanian, was a time of widespread swamps that accumulated plantmatter later to be transformed to coal.
 * 35) 240 m.y ago the continents were re-assembled into a second super continent called: pangea
 * 36) The high levels of oxygen and CO2 lead to the rise of the dinosaur in the Mesozoic.
 * 37) Dinosaur means: Terrible Lizard.
 * 38) 180 m.y ago was split apart by an upsurge in volcanism the put large amounts of CO2 into the atmosphere causing to the climate: Make more rain forest.
 * 39) The diamonds of Kimberly occur in what kind of features: in a volcano and looked like ice cream cones
 * 40) The end of the Mesozoic, 65 m.y. ago saw an extinction rate of 75% and is believed to be due to a meteor on the north end of the Yucatan Peninsula in Mexico.
 * 41) The tombstone meteorite contains the rare element: Iridium
 * 42) At the same time great outpourings of lava in were adding dust and gasses to the atmosphere: India
 * 43) The demise of the dinosaurs led to the expansion of the as the new dominant life form: mammals
 * 44) The Alps represent the collision of Africa and Europe.
 * 45) The top of the Matterhorn has rocks from: Africa
 * 46) All mountains owe their origin to: Plate tec tonics.
 * 47) The height of mountains is a determined by what two major processes: up lift and erosion
 * 48) The uplift of the Plateau by the American plate over riding the Colorado plate has caused the Colorado River to cut the Grand Canyon.
 * 49) About 2 m.y. ago the Isthmus of Panama was formed disrupting ocean currents and bringing on the Ice Age.
 * 50) Land Bridge closed the isthmus.
 * 51) Glaciers move like slow moving: Rivers
 * 52) What major American city was once covered by a massive glacier: New York City
 * 53) Deposits from glaciers created Long Island and Cape Cod.
 * 54) The basins of the Great Lakes were carved by the glaciers.
 * 55) The retreat of icecaps and glaciers most recently occurred how many years ago: 10,000
 * 56) Do geologists think there will be another advance of the icecaps and glaciers: Yes
 * 57) The Great Plate Tectonic "machine" will someday STOP.
