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...

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 ...

OCR A-Level Geography Updated Exam | Questions and Answers 100% CORRECT What are the 3 layers of the Earth? Correct Answer: *Crust* *Mantle* *Core* (inner and outer) What separates the crust and the mantle? Correct Answer: *Moho* What 2 layers does the upper mantle consist of? Correct Answer: *Lithosphere* (semi-core) Varies in thickness Boundary with asthenosphere difficult to define (melts and becomes incorporated in asthenosphere) *Asthenosphere* extends 100-300km Sem...

Earth Science-Exam 1 Questions and Answers 100% Pass What are the two main types of Earth's crust? Oceanic and Continental Explanation: The Earth's crust is divided into two main types: the oceanic crust, which forms the ocean floors, and the continental crust, which forms the continents. Which type of crust has higher density? Oceanic Explanation: Oceanic crust is denser than continental crust due to its composition of basaltic rocks. Which type of crust is thicker? ...
