"Glaciations" Natural Recordings by Native Speakers
Glaciations refer to periods of time when the Earth's climate was sufficiently cold that large portions of the planet's landmasses were covered in ice sheets, glaciers, or permanent snow.
To glaciate means to become covered or frozen with ice, or to cause something to become or appear frozen with ice. It can also refer to the process of glaciers forming or spreading.
Glaciologists are scientists who study glaciers, which are large, slow-moving rivers of ice that are formed on land by the accumulation and compaction of snow that is compressed into the ice form. Glaciologists may work on glaciers found in polar regions, mountainous areas, or even in terrestrial environments like ice sheets and ice shelves. They investigate the structure, dynamics, and behavior of glaciers, as well as their impact on the environment and global climate.
