HOW DOES AN AVALANCHE START
Have you thought about how a avalanche starts? Well I'll
tell you how.
There are two things needed to start a avalanche. One is a snow
slope; another is a trigger like a strong winds, a skier, or
a person's voice.
KINDS OF AVALANCHE
know that there are more than 1 kind of avalanche? One is called a sluff.
It starts when the weak layer of snow is on top of the the snowpack.
A snowpack is when the snow that is falling hits the ground and the pressure
of the snow on top makes it pack together like a snowball to make a snowpack.
The sluffs aren't very dangerous because they do not carry a lot of snow with
avalanches are a lot more deadlier than a sluff. Why is because the
weak layer of snow is deep in the snowpack so when it hits the snow that
is packed together strikes first. While it is traveling down a mountain
the speeds of a slab can reach up to 200 MPH. When it stops it as hard
as concrete. That is 1 reason why the slab is a lot deadlier than a sluff
because it's a lot harder to dig somebody out if they get caught under
