2. THE GRAND CANYON
The Grand Canyon is located in Arizona and
stretches to Colorado. The canyon was created by
the Colorado River over a 5.4 million year period.
The Grand Canyon’s oldest sedimentary rocks
date back almost 2 billion years. For hundreds of
years, native American tribes have lived in the
Grand canyon.
The Grand Canyon is 277 miles long, up to 18
miles wide and 5000 feet deep.

4. THE WAVE
The Wave is a sandstone rock formation located in the United
States of America near the Arizona and Utah border on the
slopes of the Coyote Buttes, in the Paria Canyon-Vermilion
Cliffs Wilderness, on the Colorado Plateau. It is famous
among hikers and photographers for its colourful, undulating
forms. The Wave is made of Jurassic-age Navajo Sandstone
that is approximately 190 million years old. Scientists who
study The Wave say that the old sand dunes turned into hard
compacted rock over the ages, calcifying in vertical and
horizontal layers. Erosion by wind and rain has created the
spectacular landscape which appears now. The soft
sandstone of The Wave is fragile.

6. NIAGARA FALLS
The Niagara Falls span across the New York state of the
United States of America and the Ontario Province of
Canada. The waterfall came into existence when the
Wisconsin glacier began retreating somewhere around
10,000-12,000 years ago. The Niagara Falls basically
comprises of three waterfalls - the American Falls, the
Horseshoe Falls and the relatively smaller Bridal Veil
Falls. In terms of width, all the three falls span across a
distance of 2,600 feet which makes it the second largest
waterfall in the world.
