Epochs are typically defined by major events in the Earth&#8217;s history, such as the formation of new continents or the extinction of major groups of organisms.<\/p>\n<p>The Phanerozoic eon, for example, is divided into the Paleozoic, Mesozoic, and Cenozoic eras. The Paleozoic era is further divided into the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian periods. The Mesozoic era is further divided into the Triassic, Jurassic, and Cretaceous periods. The Cenozoic era is further divided into the Paleogene, Neogene, and Quaternary periods.<\/p>\n<p>The Quaternary period is the most recent epoch, and it is still ongoing. It is divided into the Pleistocene and Holocene epochs. The Pleistocene epoch is characterized by repeated glaciations, while the Holocene epoch is characterized by the current interglacial period.<\/p>\n<p>Aeons are the longest units of geological time, and they are typically defined by major events in the evolution of the universe. The Phanerozoic eon, for example, is part of the Proterozoic aeon, which is part of the Archean aeon, which is part of the Hadean aeon.<\/p>\n<p>Stages are the shortest units of geological time, and they are typically defined by <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n            <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div>     <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> minor events in the Earth&#8217;s history.
