Arches National Park, Utah

Rating:

Arches National Park, home to 2,000 known natural arches as well as numerous spires, fins, windows and natural bridges, is a fun place to take curious kids. Even those under the age of 9. Why? At Arches National Park science is real. Here, kids can see, first hand, the effects of water and wind on the shape of the land. And geology isn’t the only natural science that comes to life at this U.S. national park. Potholes and biological soil crusts, two unique natural features, are home to living organisms and offer children, as well as adults, a peek at biology. Even jaded teens are sure to confess, ‘This is neat stuff!’

There are several fun facts about natural arches that make learning fun. Did you know that:

Natural arches are formed by erosion, the movement of rock and soil from one place to another.
Erosion doesn't happen by itself it needs a helping hand or agent such as wind, water and ice. Water is principle agent in arch formation.
Not all natural arches are the same. They are classified by their shape. Freestanding, cliff-wall and jug handle are but a few.
Natural arches aren't the same as natural bridges. Natural arches are formed by freestanding water whereas natural bridges are fashioned by flowing streams.
Natural arches shouldn't be confused with tafoni. Tafoni are formed primarily by weathering, the process of breaking down rocks, rather than erosion.
