Rocks and minerals are all around us and used in our everyday lives. They also help us to develop new technologies. Rocks and minerals are used in building material, cars, roads, appliances and even in cosmetics. Humans need to consume minerals on a daily basis in order to maintain a healthy lifestyle that includes strengthening the body. Abiotic features, like rocks and minerals, play a valuable role in our natural systems such as providing soil nutrients in Redwood where the tallest trees in the world grow or provide habitat like the cliffs at Grand Canyon National Park where endangered condors nest. We can learn more about Earth's materials, structure, and systems through studying rocks and minerals.
"Natural objects, such as rocks and minerals, contribute to the beauty and wonderment of the National Parks and should be left, as they were found, so that others can experience a sense of discovery." - https://www.nps.gov/subjects/geology/rocks-and-minerals.htm

Hottest, Driest, and Lowest National Park: Steady drought and record summer heat make Death Valley a land of extremes in this "below-sea-level basin". Each "extreme has a striking contrast": towering peaks are frosted with winter snow, rare rainstorms bring vast fields of wildflowers, lush oases harbor tiny fish along with refuge for wildlife and humans. "Despite its morbid name, a great diversity of life survives in Death Valley."
