Yep, More Glaciers

Ever wonder how a glacier is formed?  Well the perks to being in this line of work, I get to learn about all interesting ponderings (is this a word?) such as this.  So let’s break it down.  Glaciers are gigantic conglomerates of rocks and ice.  When a layer of snow is deposited, added, to a glacier it freezes.  As more of these sheets of ice build up it adds weight to the mass and then creates movement.  Well, gravity helps aid this too.  Then once in motion, just like the bottom of your shoes, glaciers pick up dust and rock particles.  However, these dust and rock particles relatively speaking are the size of automobiles and houses.  It’s a continuous collection of snow, ice, and rock debris.  You can see from the models below the terminus, outer edge or end, of a glacier marked by the sharpie outline.  You’ll also notice erratics, globs of boulders left behind, and moraine (rock particles left in the wake).

 

Totally unrelated . . . Huge shout out to Rylie for rocking it in the Estuaries Poster Contest, bringing in 3rd overall in the 4th grade.  Her work was displayed at the local Lowes Foods Grocery and prominently put up in front of our room for all other aspiring artistic environmentalist to envy.
