Earth&#8217;s Crust: Silicon and Oxygen<\/strong><\/p>\n\n\n\n<p>The Earth&#8217;s crust, the outermost solid shell, is composed primarily of <strong>silicon (Si)<\/strong> and <strong>oxygen (O)<\/strong>. These two elements combine to form silicate minerals, which make up over 90% of the Earth&#8217;s crust. The most abundant of these minerals include quartz (SiO\u2082) and feldspars. Oxygen makes up about 46% and silicon about 28% by weight of the crust. Their abundance is due to their chemical stability and ability to form compounds like silicates, which are common in igneous, metamorphic, and sedimentary rocks.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>2. Universe: Hydrogen and Helium<\/strong><\/p>\n\n\n\n<p>The universe is dominated by <strong>hydrogen (H)<\/strong> and <strong>helium (He)<\/strong>, which are the lightest and simplest elements. Hydrogen makes up roughly 74% and helium about 24% of the universe by mass. These elements were formed in the first few minutes after the Big Bang through a process called <strong>Big Bang nucleosynthesis<\/strong>. Stars primarily burn hydrogen into helium through nuclear fusion. Heavier elements exist but in much smaller quantities, typically formed in the cores of stars and during supernova explosions.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>3. Entire Earth: Oxygen and Iron<\/strong><\/p>\n\n\n\n<p>When considering the entire Earth, including the mantle and core, <strong>oxygen (O)<\/strong> and <strong>iron (Fe)<\/strong> are the most common elements. Oxygen remains the most abundant due to its presence in silicate minerals throughout the mantle. Iron, on the other hand, dominates the Earth\u2019s core, making up about 35% of Earth\u2019s total mass. The core is mostly iron-nickel alloy, contributing significantly to the planet&#8217;s magnetic field.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n","protected":false},"excerpt":{"rendered":"<p>Match the location with its two most common elements.
