THE GRAND CANYON

The Grand Canyon- one of the finest examples of arid-land erosion in the world

The Grand Canyon was created by rock layers over 250 million years old eroded away and deposited elsewhere. The canyon encompasses 1,218,375 acres and lies on the Colorado plateau in northwestern Arizona.

Forests are found on higher elevations and the lower elevations are made up of a series of desert basins. It has a rich and diverse fossil collection, a vast collection of geological features and rock types, four eras of geological time, and numerous caves containing extensive and significant geological, paleontological, archeological, and biological resources.

Interaction to people

I believe that this canyon will soon become a national park by Theodore Roosevelt in 1908. It will get over 5 million visitors each year and will become one of the most popular tourist attractions in the United States. People will do many activities in the canyon such as: hiking and camping (which will probably be the the most popular thing), air tours, tour by jeep, and tons of RV trips.

THE RING OF FIRE

The Ring of Fire- a string of over 452 volcanoes

The Ring of Fire is the result of plate tectonics, a convergent boundary formed by tectonic plates crashing into each other. Convergent boundaries are often subduction zones, where the heavier plates slip under the lighter plate. These sites are often sites of volcanoes, as the heavier plate melts back into earths mantle.

The Ring of Fire is a string of volcanoes and a site of volcanic activity. The ring isn`t quite a circular ring, rather more like a 40.000 kilometer horseshoe. A string of 452 volcanoes stretch from the southern tip of South America, up along the coast of North America, across the Bering Strait bridge, down through Japan, and into New Zealand.

Interaction to people

I predict there will be a Ring of Fire Tour that will take you across Cook Inlet from Homer and Kachemak Bay to the active volcanoes in the Aleutin and Alaska Ranges. Not only will they fly around the craters of these magnificent volcanoes, but also have vies of giant glaciers.

The ring causes not only volcanic activity, but also severe earth quakes, which often injure the people living near the ring. The 1982 eruption of El Chichon will kill about 2,000 people who live there, and injure many more. The ring will also cause more tragedies in the future.

NIAGARA FALLS

Niagara Falls

Niagara Falls was created when glaciers receded at the end of the Wisconsin glaciation, the last ice age about 10,00 years ago. The ice melted and water from the newly Great Lakes carved a path through the Niagara Escarpment en route to the Atlantic Ocean.

Niagara Falls is located on the border of the United States and Canada. The Niagara River The deepest section in the Niagara River is just below the Falls, the river is so deep it equals the height of the Falls above, 52 meters. More than 168,000 cubic meters of water go over the Falls every minute during daytime tourist hours.

Although Niagara Falls is not the tallest waterfall in the world, its height and volume is so beautiful, it attracts thousands of tourists a year.

Interaction to people

About 22,500,000 people will visit Niagara Falls every year. Many people will participate in boat tours, but the majority of people come to take in the views of the falls. Niagara Falls will become a state park and get millions of visitors a year.

People who are daredevils will even go off the top of the falls in a barrel or capsule. Many will not survive, some will get severely injured, and only a handful of people will survive unharmed.
