The Earth - origin of Earth, oceans, life; the Earth's internal layers... - origin of Earth, oceans, life; the Earth's internal layers... Origin of Earth, Oceans, Life: • Earth: Supernova (explosion of a star-4.6 bya)- earth (nebula made of gas and dust) was formed 4.5 billion years ago. • Oceans: Volcanic expulsion, rained for thousands of years then hit by icy comets; volcanic outgassing and ice from comets • Life: 3.7 billion years ago life was created- animals have been arou...

origin of earth - Answer-• Supernova: death of a star (great explosion) • Supernova happened 4.6 bya, dust and gas flattens to a disk and spins faster due to gravity and solar nebula formed. • Solar Nebula: describes formation of Earth 4.5 bya • Nebula: gas cloud origin of oceans - Answer-• volcanic explosion, H2O condensed and rained down for thousands of years to create oceans • icy comets hitting earth (responsible for 1/2 of earths ocean water) origin of life - Answer-•...

List the 3 main layers of the earth from the center to the outside based on composition (what they are made out of). - Answer-1). Core (Inner and outer)-solid inner liquide outer. Iron/nickel alloy. Extreme pressure 2).Mantle-82% of the earth's volume-Solid, rocky, shell 3). Crust (Oceanic-younger rocks and Continental-granite rocks) List the 5 mechanical layers of the earth (based on how they deform?) Whic layers is a liquid? - Answer-1.The lithosphere is the outermost mechanical layer a...

How was the solar system formed? - -a supernova (explosion of a start when it runs out of fuel) -4.6 billion years ago how was the earth formed? - -a nebula made of gas and dust -was formed 4.5 billion years ago how did oceans form? - -A volcanic expulsion - rained for thousands of years -hit by an icy comets -volcanic out gassing and ice from comets when did life form? - -3.7 billion years ago how long have animals been around for? - -600 million years ago how long has pho...

What is the lithosphere? CORRECT ANSWER crust and upper mantle What is the asthenosphere? CORRECT ANSWER the upper layer of the earth's mantle, below the lithosphere deformable--like playdough Continental lithosphere CORRECT ANSWER -thick -old(4byo) -not dense -many types of rocks oceanic lithosphere CORRECT ANSWER lithosphere that is mainly comprised of basalt; it is more dense that is why it sits lower in the asthenosphere. -thin -young(200 myo) 3 types of plate boundaries...

Theory of Plate Tectonics - Answer A theory stating that Earth's lithosphere is broken into huge plates that move and change in size over time - explains the process of continental drift - theory is a fusion on the theories of continental drift and seafloor spreading - continents are not floating on the ocean, rather they are rooted What are the 10 major plates of the Earth's lithosphere? - Answer African, Antarctic, Australian, Eurasian, North American, South American, Pacific, Cocos, N...
