Ice sheet
Ice sheet, also known as a continental glacier, is a mass of glacial ice that covers surrounding terrain and is greater than 50000 km2.

Last Glacial Period
The Last Glacial Period (LGP), also known colloquially as the last ice age or simply ice age, occurred from the end of the Eemian to the end of the Younger Dryas, encompassing the period years ago.
The LGP is often colloquially referred to as the "last ice age", though the term ice age is not strictly defined, and on a longer geological perspective, the last few million years could be termed a single ice age given the continual presence of ice sheets near both poles.
Sea level rise
Tide gauge measurements show that the current global sea level rise began at the start of the 20th century.
This acceleration is due mostly to climate change, which heats (and therefore inflates) the ocean and which melts the land-based ice sheets and glaciers.
Ice
Water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or 32 degrees Fahrenheit.
Sufficiently thin ice sheets allow light to pass through while protecting the underside from short-term weather extremes such as wind chill.
Laurentide Ice Sheet
The Laurentide Ice Sheet was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glacial epochs, from 2.58 million years ago to the present.
Last Glacial Maximum
The Last Glacial Maximum (LGM), also referred to as the Late Glacial Maximum, was the most recent time during the Last Glacial Period that ice sheets were at their greatest extent.
Greenland ice sheet
Vast body of ice covering 1710000 km², roughly near 80% of the surface of Greenland.
The ice sheet is almost 2900 km long in a north–south direction, and its greatest width is 1100 km at a latitude of 77°N, near its northern margin.
West Antarctic Ice Sheet
Segment of the continental ice sheet that covers West Antarctica, the portion of Antarctica on the side of the Transantarctic Mountains that lies in the Western Hemisphere.
The WAIS is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice shelves.
Patagonian Ice Sheet
The Patagonian Ice Sheet was a large elongated and narrow ice sheet centered in the southern Andes that existed during the Llanquihue glaciation.
Sea level
Average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured.
Some land movements occur because of isostatic adjustment of the mantle to the melting of ice sheets at the end of the last ice age.
