Plate margins - Study guides, Revision notes & Summaries

What is the origin of the Earth? - Answer-Formed out of a solar nebula What are the origins of Life? - Answer-Archaea - the oldest origin of life on Earth What is kinetic energy? - Answer-The energy of motion What is heat energy? - Answer-Energy created by particles of matter rubbing together What is density? - Answer-A measurement of the amount of matter in a given volume of something. (mass per unit volume) What is convection? - Answer-Transfer of heat through currents caused by differen...

With respect to a mineral commodity, the definition of the "resource" is: A) the economic amount of the commodity extracted B) a local accumulation of a specific mineral that contains that commodity C) the total number of mineral deposits of that commodity D) the amount of the commodity that exists in the Earth E) the estimated total amount of that commodity that is ultimately economically recoverable - E The process of erosional unloading can produce: A) Leaching B) Mud Cracks C) Pil...

This document contains notes on the topic of Plate margins and plate tectonics that will be useful when studying Geography in KS3 or GCSE. The information has been gathered and paraphrased from various articles, textbooks, and lectures.

What does plate tectonics refer to? correct answers It is a theory explaining the movement of the Earth's crust -Earth's crust is not solid but rather a bunch of pieces (or 'plates') that move on the surface of the Earth. Similar to cracked egg shell. We need all three boundary types for plates to move around Earth's surface: -Convection currents -- drives the movement -Mid-ocean ridge -- spreading center Subduction zones -- oceanic trench site of crust destruction What is the maj...

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-•...

Earth's Structure - ANSWER-- Inner core is 6000°C made up of solid iron and nickel - Outer core liquid melted 2,000 Km thick - Mantle semi molten Asthenosphere - ANSWER-The upper semi molten part of mantle Lithosphere - ANSWER-The rigid mantle and crust Types of crust - ANSWER-- Continental- 30-70 km thick and less dense - Oceanic- 6-10 km thick and more dense Convection currents - ANSWER-- Lower parts of mantle rise as heated up, cool down become more dense and slowly sink - Circula...

Interphase - cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases G1 phase - the cell grows in size and organelles double in size S phase - DNA replication ("S"= synthesize) G2 phase - cell growth, production of enzymes and other proteins two categories of mitosis - 1. karyokinesis (division of cell nucleus) 2. cytokinesis (division of cytoplasm) prophase - 1. chromatin condenses to form chromosomes; nuclear membrane and nucleoli disapp...
