It details the composition of the Earth's core, mantle, and crust, distinguishing between continental and oceanic crust characteristics. Furthermore, the content explores how geophysical and geological surveys reveal the Earth's interior composition. It explains plate tectonics as the movement of the lithosphere over the asthenosphere, describing how major plates interact to shape the crust through collisions, separations, and friction. This resource is ideal for introductory earth science studies, offering clear insights into planetary mechanics, lithospheric structure, and the processes that drive global geological changes.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/the-structure-of-the-earth-and-plate-tectonics/657780/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/the-structure-of-the-earth-and-plate-tectonics/657780.png","ImageObject",300,407,{"name":42,"@type":43},"Marglet","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-10-26",true,{"@type":52,"interactionType":53,"userInteractionCount":30},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"What are the three main layers of the Earth?","Question",{"text":62,"@type":63},"The Earth is comprised of the core, the mantle, and the crust.","Answer",{"name":65,"@type":60,"acceptedAnswer":66},"What is the difference between continental and oceanic crust?",{"text":67,"@type":63},"Continental crust is thick and buoyant, consisting mostly of older rock, whereas oceanic crust is thin, dense, and typically younger, causing it to sink beneath the continental crust.",{"name":69,"@type":60,"acceptedAnswer":70},"What defines the lithosphere?",{"text":71,"@type":63},"The lithosphere is the rigid outer layer of the Earth, composed of the crust and the uppermost part of the mantle.","https://schema.org",{"og:url":32,"og:type":74,"og:title":10,"og:site_name":45,"og:description":12},"article",{"robots":76,"canonical":32},"index,follow",{"doc_id":78,"site_id":7},657780,1793019007,{"code":4,"msg":81,"data":82},"success",[83,87,91,95,100,105,110,114,119,122,126],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":84,"show_sort_weight":85,"slug":86},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":88,"show_sort_weight":89,"slug":90},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":92,"show_sort_weight":93,"slug":94},"Exam",70,"exam",{"id":96,"doc_module":4,"doc_module_name":25,"category_name":97,"show_sort_weight":98,"slug":99},5,"Comic",60,"comic",{"id":101,"doc_module":4,"doc_module_name":25,"category_name":102,"show_sort_weight":103,"slug":104},6,"Technology",50,"technology",{"id":106,"doc_module":4,"doc_module_name":25,"category_name":107,"show_sort_weight":108,"slug":109},7,"Healthcare",40,"healthcare",{"id":111,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":112,"slug":113},8,30,"research-report",{"id":115,"doc_module":4,"doc_module_name":25,"category_name":116,"show_sort_weight":117,"slug":118},9,"Religion & Spirituality",20,"religion-spirituality",{"id":117,"doc_module":4,"doc_module_name":25,"category_name":120,"show_sort_weight":117,"slug":121},"World Cup","world-cup",{"id":123,"doc_module":4,"doc_module_name":25,"category_name":124,"show_sort_weight":123,"slug":125},10,"Lifestyle","lifestyle",{"id":127,"doc_module":4,"doc_module_name":25,"category_name":128,"show_sort_weight":96,"slug":129},19,"General","general",{"code":4,"msg":81,"data":131},{"doc_id":78,"user_id":132,"nickname":42,"user_avatar":133,"doc_module":4,"category_id":111,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":30,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":139,"language":140,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":141,"faqs":142,"seo_title":143,"seo_description":12,"update_tm":144,"read_time":145},2336477982702,"https://ap-avatar.wpscdn.com/davatar_9964176cb1d06d4a9deccf72a44ae3dc","University of  \nBRISTOL  \nThe Structure of the Earth andPlate Tectonics  \n# Structure of the Earth\n\n·The Earth ismade up of 3main layers:-Core-Mantle-Crust  \nCrustYOUR PLANET  \n# The Crust\n\n·This is where we live!  \n·The Earth's crust is madeof:  \nContinental Crust  \nOceanic Crust  \n-thick(10-70km)  \n-thin(~7 km)  \n-dense (sinks undercontinental crust)-young  \n-buoyant (less dense  \nthan oceanic crust)  \n-mostly old  \nHow do we know what theEarth is made of?
