Rocks and Minerals NG 2021 Wall Calendar

Product Information

More than 4,000 naturally occurring minerals have been found on earth. They hold the tangible evidence that scientists need to learn about our world. Modern civilization relies heavily on mineral resources. You use minerals every day – more than you may imagine. Many minerals form beautiful crystals; the most prized of all are gemstones. Uncut gems often look fairly ordinary–like rocks. Its only when they are cut and polished that they obtain the brilliance and luster that gives them their value. National Geographic Rocks and Minerals 2021 features specimens of amazing form and color. Each image in this 12-month calendar is accompanied by information highlighting the characteristics of the mineral and a spacious grid with major holidays and moon phases. There are sections at the back of the calendar to record emergency contact information, birthdays/anniversaries, and a full-page 3-year at-a-glance. This calendar makes a great gift for rock and mineral buffs. Earth friendly, printed with soya-based inks on Forest Stewardship Council certified paper.
