The design\u00a0usually takes years to see since it depends on the plants growing. This type of geoglyph is\u00a0called an arborglyph.<\/li>\n<li>Another type of geoglyph often referred to as\u00a0\u2018chalk giants\u2019 are\u00a0those carved into hillsides exposing the bedrock beneath.<\/li>\n<li>Geoglyphs in History:\n<ul>\n<li>From ancient times, the most widely known geoglyphs are the\u00a0Nazca Lines of Peru, which have been a mystery to this day.\u00a0<\/li>\n<li>Other geoglyphs from the past include the\u00a0Megaliths in the Urals, the\u00a0Uffington White Horse, the Long Man of Wilmington, and many others.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2>Features of the Geoglyph unearthed from Telangana<\/h2>\n<ul>\n<li>Etched on a low-lying granitoid hillock, the geoglyph spans\u00a07.5 metres in diameter and has a\u00a0perfect circular shape.<\/li>\n<li>Surrounding the circle is a\u00a030-centimetre-wide rim, and\u00a0within the circle are two triangles.\u00a0<\/li>\n<li>It is\u00a0dated to the Iron Age, specifically\u00a0around 1000 BCE.\u00a0<\/li>\n<li>It is suggested that this circle\u00a0might have served as a model for megalithic communities in planning their circular burial sites.<\/li>\n<\/ul>\n<h2>Key facts about Nazca Lines<\/h2>\n<ul>\n<li>The lines are a\u00a0group of massive geoglyphs in southern\u00a0Peru\u2019s Nazca Desert.<\/li>\n<li>Experts estimate that they were designed anywhere in the\u00a0period from 500 BCE to 500 CE.<\/li>\n<li>Some\u00a0of the\u00a0lines are straight,\u00a0while others depict designs of animals and plants.<\/li>\n<li>All the lines have a\u00a0combined length of\u00a0more than 808 miles, while they cover an area of around 19 square miles.<\/li>\n<li>An individual design has a width of between 0.2 and 0.7 miles.<\/li>\n<li>All the\u00a0designs were made by removing the top layer of soil. The depth of a line is anywhere between four and six inches.<\/li>\n<li>Some of the shapes are visible from a height of as much\u00a0as 1,500 feet.<\/li>\n<li>The preservation of the lines over the years\u00a0can be attributed to the dry and windless climate of the region.<\/li>\n<\/ul>\n<hr \/>\n<h3>Q1) What are clastic rocks?<\/h3>\n<p>Clastic rocks are the broken bits and pieces of older rocks that lithified (turn to stone) and became new rocks. The broken bits and pieces of older rocks are clasts. Clasts can be as tiny as the dust on the sill of a window or large boulder.<\/p>\n<p><strong>Source: <\/strong><a href=\"https:\/\/www.thehindu.com\/sci-tech\/science\/3000-year-old-iron-age-geoglyph-circle-discovered-in-telangana\/article67504746.ece\" target=\"_blank\" rel=\"nofollow noopener\"><u>\u20183,000-year-old Iron Age\u2019 geoglyph circle discovered in Telangana<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Geoglyph is a large design or motif (generally longer than 4 metres) produced on the ground.<\/p>\n","protected":false},"author":5,"featured_media":16801,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-16800","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/16800","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=16800"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/16800\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/16801"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=16800"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=16800"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=16800"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
