Dictogloss on Glaciers
Glaciers are huge masses of ice. They flow like slow rivers.
They form from the snow that stays in one spot year-round.
It accumulates into ice and pressure turns it into grains, similar t
o sugar. Glaciers can look dusty and rocky while some can have
a marin aqua colour as if there is a light illuminating inside it.
There are 2 types of glaciers. Alpine glaciers. Alpine glaciers
are glaciers on hills or mountains. They move downhill and have
the ability to drastically change the shape of valleys. They go from
V-shaped to U shaped whenever an Alpine glacier moves downhill.
Continental Sheets are types of glaciers that can spread across a
certain area. They could even go further.
Glaciers can be hundreds of thousands of years old. In New Zealand,
we have 2 major glaciers of our own. The Franz Josef glacier and the
Fox Glacier. You are able to hike these magnificent landforms but be
careful of the small crevasses because you can fall down them,
they have very thin ice.
10 percent of the world’s Glaciers covers the earth.
There use to be ⅓ that covered the planet but due to Global
Warming, many have melted leaving us with 10 percent left. It is
also known that glaciers hold the world’s supply of freshwater.
The Lambert glacier is the biggest glacier in the world. It's
2.5km deep. There are 100000 that are unnamed and 99 percent is
in Greenland Antartica.
