Perito Moreno glacier, what you wish to
know
Every year the Perito Moreno glacier generate expectations within the world
relation to its breakup. Some information on its features and its history can
facilitate us perceive this phenomenon.
Los Glaciares park was created in 1937 for the preservation of the glaciers
and was declared a World Heritage site by UNESCO to protect its flora and fauna
at risk of extinction.

Glaciers play a vital role in our day, occupy 100% of the land surface and
account for ninetieth of the world's water. And with the air and water flow
that make, contribute to balance the Earth's climate, that without them would
be breathless.
There are several myths and comments on the Perito Moreno glacier and its
behavior that each year surprise and invites tourists from all over the world.
however to start to know, we should ask:
What is a glacier?
A glacier is commonly compared to a stream of ice as a result of it have
tributaries, erosive capacity, and greater speed within the middle of the
channel than at the sides. however the movement of ice, like all bodies, follow
the laws of gravity and extremely specific behaviors that have very little in
common with the water.

The ice of glaciers is the results of compression of the snow impact of its
own weight. For the formation of a glacier takes giant snow and the average
annual temperature for holding snow. The snow accumulates and compressed in layers that are compacted and by the
weight it form the ice.
The time needed for the formation of ice from the snow differs exceedingly
from one glacier to a different looking on 2 factors: the snow and temperature
and might vary from a dozen years like within the alpine glaciers or glaciers
from Patagonia or many hundreds of years like in Antarctica.
The vital thing to understand regarding the glacier is that's not solely a
mass of ice, however particularly, a mass of moving ice. And as everyone in
motion, the ice is influenced by gravity. thanks to this similarity with water
the glaciers are compared to streams that, if it's not entirely false, in light
of recent studies additionally doesn't' appear to be quite true.
A glacier is just a glacier if it moves and to begin to move the ice
desires a particular thickness of regarding twenty meters. From here, 3 factors
can condition the forward speed of a glacier: the thickness, slope and ice
temperature.
