Did you know that sedimentary rocks are often formed from the accumulation of organic materials? Think of it as nature’s recycling program! Over millions of years, layers of mud, sand, and organic matter like shells and plants get compacted and cemented together, creating treasures like limestone and sandstone that tell stories of ancient environments. When it comes to rock transformation, sandstone morphing into quartzite is a dazzling process of metamorphosis! This occurs under intense pressure and heat, which rearranges the sand grains into a denser, more durable rock. It's like giving the sandstone a tough makeover, resulting in a beautiful and resilient quartzite perfect for countertops and other construction uses!
