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...

LUOA Earth Science Module 8 (2023/2024) Already Passed Glossopteris was a temperate climate leaf fossil. He found it in Antarctica. How could this be? Because that fossil was supposed to have been in a temperate climate near the equator but instead was in Antartica, meaning that the continents have moved since the beginning of time. Alfred Wegener discovered rocks in the Appalachian Mountains matched rocks in _______________________. Europe and Greenland Originally, Wegener's hypothesis that...

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-•...
