We just learned about the Melt Pond.

Another part of Antarctica is glacial Meltwater.

Sometimes the ice or snow in Antarctica will melt a little, and turn into what is called meltwater.
Meltwater is different than the ocean water around Antarctica because it is fresh water.
This means animals can drink it, and it also means it can mix with the ice and snow of the glaciers and melt and refreeze over and over.
The meltwater usually melts because of the warmer summer weather, from magma underground, or from volcanic eruptions.

If the water stays in one place on top of the snow or ice, that is the melt pond.
Other times the melted snow or ice will turn into a small river and flow across the snow and ice.
There are even times when the snow or ice will melt underneath the top part, and make a small lake underneath the snow or ice.

Sometimes the meltwater is underground and is between two glaciers.
When this happens the glaciers can move around as they are sliding on the water in between.

Scientists study meltwater because it can help them understand climate change and how glaciers move.
