EARTH SCIENCE FINAL EXAM QUESTIONS AND ANSWERS ALREADY PASSED What are the three primary layers of Earth, arranged from the center to the exterior, based on their composition? 1) Core - Comprising both a solid inner core and a liquid outer core, this layer consists mainly of an iron-nickel alloy and is under immense pressure. 2) Mantle - Occupying 82% of Earth’s volume, it is a solid, rocky layer surrounding the core. 3) Crust - The outermost layer, with oceanic crust featuring ...

big bang - -still energy left from explosion -discovered in 1960s -assumes earth came from material -Kant created most pop model of formation (planet accretion) nebula - beginning form of planets many bump into others and combine earths composition - -more dense material in center -heterogeneous (bc heat and dense elements melt and flow) -accretion -compression -radioactive decay 3 layers of earth - -based on composition -core, mantle, crust -metallic core sank to center lithospher...

Test 1 SCI 225How is solar radiation distributed on Earth's surface? - correct answer hottest towards the equator because of its direct rays hitting the earth directly. What is law of superposition? - correct answer oldest rocks are on the bottom. How can you determine the age of the seafloor? - correct answer The youngest crust of the ocean floor can be found near the seafloor spreading centers or mid-ocean ridges. As the plates split apart, magma rises from below the Earth's surface to...

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...
