What are glaciers? How were they created? Art they threatened?

Glaciers are large masses of ice that form on land when snow accumulates over many years and compacts into a thick layer.

Glaciers are created when temperatures remain cold enough for snow to accumulate over many years and form large, thick ice masses.

Glaciers can be found in many places around the world, including the Arctic, Antarctica, Alaska, and the Rocky Mountains.

Glaciers are constantly in motion, slowly moving downhill due to the force of gravity and their own weight.

Glaciers can cause flooding, avalanches, and other natural disasters.

Glaciers are threatened by global warming, which causes them to melt and retreat, leading to sea level rise.

Examples of famous glaciers include the Columbia Glacier in Alaska, the Baltoro Glacier in Pakistan, and the Franz Josef Glacier in New Zealand.
