GRAND CANYON
The Grand Canyon
became a national
park in 1919. One
reason the Grand
Canyon became an
official national park
is of it’s size, another
reason is it is a
national land mark.
WHAT YEAR DID THE GRAND CANYON BECOME AN OFFICIAL NATIONAL PARK AND
WHY?
The Grand Canyon
was formed by the
powerful erosive
system of a river. And
erosive forces still
form the grand
canyon today!
HOW WAS THE GRAND CANYON FORMED?
The types of rock
you can find at the
grand canyon are
Limestones, shales,
sandstones, granite
and schist. I believe
there is more but I
don’t know those.
WHAT TYPE OF ROCK CAN BE FOUND IN THE GRAND CANYON?
One of the Grand
Canyon’s features
are that the grand
canyon has estimated
of 1,000 caves
hidden within the
Canyon, also the
grand canyon is
renowned for its large
size
WHAT SPECIAL LANDFORMS OR FEATURES DOSE THEE GRAND CANYON HAVE?
It’s
changing
by the
erosion of
the river
going
through
the grand
canyon
How is the Grand Canyon inside currently changing?
One thing is that fish species
are disappearing in the river.
Other issues is the quality of
the air, and the ability to
manage fires, which also
impacts the air.
Another one is the many,
many visitors who keep
coming to visit and they litter
and hurt the canyon.
Finally, there is air pollution;
see the haze in the picture.
WHAT ENVIRONMENT ISSUES ARE EFFECTING THE GRAND CANYON?
Technology helps maintain
and preserve the Grand
Canyon in a couple of ways.
First, they use lasers and
sonars to map the sand loss
in the canyon.
Second, they put microchips
in fish to watch endangered
fish and their movement in
the river.
There are also solar panels’

CANYON?
