power. Examples of such natural occurrences are hurricanes, tornados, wildfires, volcanic eruptions, flooding, earthquakes, and tsunamis. These are usually not caused directly by humans, but their effects live with us for a long time. In this lesson, we shall look at one of such natural occurrences&#8230; earthquakes!<\/p><h3>What is an Earthquake?<\/h3><p>In simple terms, earthquakes are the rumblings, shaking, or rolling of the earth&#8217;s surface. It is what happens when two blocks of the earth suddenly slip past one another or break apart from each other as a result of tension caused by prolonged energy build up.<\/p><figure id=\"attachment_3030\" aria-describedby=\"caption-attachment-3030\" style=\"width: 600px\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-3030\" src=\"https:\/\/eschooltoday.com\/learn\/wp-content\/uploads\/2020\/10\/tectonic-plates-and-faultlines.jpg\" alt=\"What happens to the earth's crust during an earthquake?\" width=\"600\" height=\"318\" srcset=\"https:\/\/eschooltoday.com\/learn\/wp-content\/uploads\/2020\/10\/tectonic-plates-and-faultlines.jpg 600w, https:\/\/eschooltoday.com\/learn\/wp-content\/uploads\/2020\/10\/tectonic-plates-and-faultlines-300x159.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><figcaption id=\"caption-attachment-3030\" class=\"wp-caption-text\">What happens to the earth&#8217;s crust during an earthquake?<\/figcaption><\/figure><p>Earthquakes come in many forms. It may be a shock under your feet, or it may be powerful and destructive enough to flatten an entire city. They can happen anywhere, land or sea.<\/p><h3>Foreshocks, mainshocks, and aftershocks<\/h3><p>Sometimes, there are smaller shocks that occur before (foreshock) and after (aftershock) the main earthquake (mainshock). Sometimes foreshocks are so big, and scientists are unsure if it is the mainshock. Foreshocks and aftershocks can occur for days, weeks, and months of the main earthquake.<\/p><p>Earthquakes are also called temblors.<\/p><figure id=\"attachment_3031\" aria-describedby=\"caption-attachment-3031\" style=\"width: 317px\" class=\"wp-caption alignleft\"><img decoding=\"async\" class=\"size-full wp-image-3031\" src=\"https:\/\/eschooltoday.com\/learn\/wp-content\/uploads\/2020\/10\/earthquake-earth-crust.jpg\" alt=\"What is beneath the surface of the earth?\" width=\"317\" height=\"257\" srcset=\"https:\/\/eschooltoday.com\/learn\/wp-content\/uploads\/2020\/10\/earthquake-earth-crust.jpg 317w, https:\/\/eschooltoday.com\/learn\/wp-content\/uploads\/2020\/10\/earthquake-earth-crust-300x243.jpg 300w\" sizes=\"(max-width: 317px) 100vw, 317px\" \/><figcaption id=\"caption-attachment-3031\" class=\"wp-caption-text\">What is beneath the surface of the earth?<\/figcaption><\/figure><p>It is important to understand the earth\u2019s makeup to help understand earthquakes better.<\/p><p>In this diagram, you will notice that the inner and outer core of the earth (middle part) is liquid, containing iron and nickel of extreme temperatures (5,500\u00b0C).<\/p><p>The Mantle is semi-molten rock, also called magma.
