Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over millions of years.
Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario, form the Great Lakes, straddling the United States and Canada to make up the largest group of freshwater lakes in the world. Collectively they contain 5,439 cubic miles of water (22,670 cubic km), or about 20% of all the earth’s fresh water, and cover an area of 94,250 square miles (244,106 square km).
Dive in to explore water and why it is so important to life. The interactive Our Great Lakes Watershed exhibit examines how precious the world's freshwater supply is and what we as individuals can do to help protect it.
Pele’s hair is natural volcanic fiberglass formed by wind blowing through hot fountains of lava – stretching it into thin strands of yellow glass up to 2m in length. It is commonly found down wind of active vents. Pele is the Hawaiian goddess of volcanoes.
Gneiss is a high grade metamorphic formed by the deep burial and heating of its pre-existing parent rock. This specimen of the Watersmeet Gneiss is from bedrock exposures north of the town of Watersmeet in the western UP of Michigan. It contains zircon crystals dated at 3.65 by, making it Michigan’s oldest rock and one of the oldest in the USA. Zircon crystals retain their original composition at very high temperatures thus allowing for dating of Earth’s old metamorphic rocks.
