It covers essential vocabulary such as tectonic plates, plate boundaries, seismic waves, and the Richter Scale, while explaining the fundamental physical processes that trigger seismic activity. By detailing how the movement of molten rock in the Earth's mantle causes tectonic plates to shift, stick, and release pressure, the document offers a clear scientific explanation of why earthquakes occur, particularly at plate boundaries, and their subsequent effects like tsunamis and aftershocks.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":20,"@type":76,"position":81},"https://docshare.wps.com/document/exam/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/year-4-earthquakes-study-guide/493662/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/year-4-earthquakes-study-guide/493662.png","ImageObject",300,407,{"name":92,"@type":93},"Quinn Holloway","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-14","2026-10-01",true,{"@type":102,"interactionType":103,"userInteractionCount":19},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What are tectonic plates?","Question",{"text":112,"@type":113},"Tectonic plates are very large sections of rock that make up the Earth's crust and divide it into different parts.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"Why do earthquakes occur at plate boundaries?",{"text":117,"@type":113},"Earthquakes occur when two tectonic plates meet, stick together due to friction, build up pressure, and then suddenly slip past each other in a movement that releases energy.",{"name":119,"@type":110,"acceptedAnswer":120},"What is the Richter Scale used for?",{"text":121,"@type":113},"The Richter Scale is a numerical system used to measure and indicate the magnitude or severity of an earthquake.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},493662,1791884548,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":19,"category_name":20,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":19,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":8,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":143,"read_time":81},2336474466712,"https://ap-avatar.wpscdn.com/davatar_a8503ba1806abce46bf441b54a3ca4cd","Year 4 Earthquakes  \n\n| Key vocabulary |  |\n| --- | --- |\n| tremor | An involuntary, quivering movement. |\n| earthquake | A sudden, violent shaking of the ground, causing much destruction, asa result of movement in the Earth’s crust. |\n| aftershock | A smaller earthquake following the main shock of a large earthquake. |\n| tectonic plates | Very large sections of rock that make up the Earth’s crust that split the Earth into different parts. |\n| plate boundary | The place where two tectonic plates meet. |\n| friction | The action of one surface rubbing against another surface. |\n| tsunami | A long, high sea wave caused by an earthquake. |\n| seismic waves | A vibration that runs through the Earth after an earthquake. |\n| magnitude | The great size or extent of something. |\n| Richter Scale | A numerical scale used to show the magnitude of an earthquake. The more destructive earthquakes tend to have magnitudes between 5.5 and 8.9. |\n\nWhy do Earthquakes happen?  \nThere are seven major plates and lots of smaller plates. Some plate boundaries are on land and some are in the ocean. New Zealand experiences earthquakes because it sits on a plate boundary.  \nThe Earth crust is made up of parts called tectonic plates that fit together. However, some parts slide underneath eachother.  \nThe molten or melted rock in the Earth’s mantle moves. This can ~~ ~~ make tectonic plates in the thin crust move as well. Each year  \nplates move a few centimetres.  \nEarthquakes happen in places where two plates move and ~~ ~~ mainly affect areas where two  \nplates meet (tectonic plate boundaries) .  \nWhen plates slide past each other, the plates stick, pressure builds up, and the plates slip. The friction eventually goes away when the plates slip past eachother in a sudden movement, causing an earthquake.","cbCairNjLCxopCX5","https://ap.wps.com/l/cbCairNjLCxopCX5","pdf",1494656,"English","# Key vocabulary\n# Why do Earthquakes happen?","[{\"question\":\"What are tectonic plates?\",\"answer\":\"Tectonic plates are very large sections of rock that make up the Earth's crust and divide it into different parts.\"},{\"question\":\"Why do earthquakes occur at plate boundaries?\",\"answer\":\"Earthquakes occur when two tectonic plates meet, stick together due to friction, build up pressure, and then suddenly slip past each other in a movement that releases energy.\"},{\"question\":\"What is the Richter Scale used for?\",\"answer\":\"The Richter Scale is a numerical system used to measure and indicate the magnitude or severity of an earthquake.\"}]","Year 4 Earthquakes - Study Guide | PDF",1790884808]
