Cryosphere, Elementary (K-4), Lithosphere
With air, land, living things and water, too.
On a globe, two circles outline their spaces.
Antarctica is a continent. The Arctic, it is not.
North and South poles are magnetic.
On a globe, each pole is just a dot.

Flat, cold land in polar places.
On the horizon fills polar spaces.
Some polar land can be very bumpy.
Do polar mountains make it lumpy?
The South Pole is not all snow and ice.
There's rocky land. Oh, how nice.
The North Pole is all white and bare.
But is there any land under there?
The Rock Cycle works on polar land.
Big, then little rocks turn to dirt and sand.
They freeze, they thaw. They spilt and crack.
In the Arctic dirt, is that a caribou track?
Polar land is not much like my home.
Colder and dryer with more space to roam.

Some wonder if it will it last.
Antarctic ice sheets break.
Floating icebergs the pieces make.
In the Arctic sea ice floes.
Melt in summer, in winter grow.
All of us trying to understand.
How will changing polar ice change polar land?
