The term &#8220;aggregate&#8221; is key, as it signifies that a rock is a cohesive mass composed of individual mineral grains that have been cemented or interlocked together. These minerals are the fundamental building blocks of all rocks and, by extension, the Earth&#8217;s crust.<\/p>\n\n\n\n<p>The vast majority of rocks are polymineralic, meaning they contain more than one type of&nbsp;<strong>mineral<\/strong>. A common example is granite, an igneous rock easily identified by its mixture of interlocking crystals, primarily light-colored quartz and feldspar and dark-colored biotite mica or hornblende. In contrast, a few rocks, known as monomineralic rocks, are composed almost exclusively of a single mineral. For instance, marble is made of calcite, and quartzite is made of quartz. However, these are less common than their polymineralic counterparts.<\/p>\n\n\n\n<p>The properties of a rock are a direct reflection of its components. A rock\u2019s mineral composition\u2014that is, the specific types of minerals it contains and their relative proportions\u2014determines many of its physical characteristics. Among the most immediately observable of these is&nbsp;<strong>color<\/strong>. The overall hue of a rock is a composite of the colors of its constituent minerals. Rocks rich in light-colored minerals like quartz and feldspar (felsic minerals) tend to be light gray, white, or pink. Conversely, rocks rich in dark, iron- and magnesium-heavy minerals like pyroxene, amphibole, and olivine (mafic minerals) are typically dark green, gray, or black. Therefore, color serves as an important initial clue for geologists in identifying a rock and deciphering its origin.thumb_upthumb_down<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner4-867.jpeg\" alt=\"\" class=\"wp-image-231253\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Choc Fill in the blanks to complete these sentences about rock characteristics.
