Period of time when glaciers dominate the landscape of the Earth. The last major Ice Age was during the Pleistocene epoch.

A time of widespread glaciation.

1855, from ice (n.) + age (n.). Perhaps translating German Eiszeit (1837). An earlier term in the same sense was glacial epoch (1841). Local scientific men had noticed from the late 18c. evidence that [..]

last glacial period, which peaked about 20,000 years ago.

long period of cold climate where glaciers cover large parts of the Earth. The last ice age peaked about 20,000 years ago. Also called glacial age.

A major interval of geologic time during which extensive ice sheets (continental glaciers) formed over many parts of the world. The best known ice ages are 1) the Huronian in Canada, occurring very ea [..]

see glacial.

A period of time when significant amounts of ice form on the continents, inducing a fall in sea level. ick

A time when the Earth was much colder and glaciers covered a lot of its surface. The last ice age ended less than 20,000 years ago.

An ice age is a time lasting thousands of years during which the Earth is very cold and largely covered by ice and glaciers.

a glacial period or part of a glacial period; most frequently refers to the last glacial period.

a period in the Earth's past when the polar ice caps were much larger than today

A time of widespread glaciation (see Pleistocene). Igneous Rock:

A time of widespread glaciation (see Pleistocene).

An ice age or glacial period is characterized by a long-term reduction in the temperature of the Earth's climate, resulting in growth of continental ice sheets and mountain glaciers (glaciation).

A glacial epoch or time of extensive glacial activity. Also, as Ice Age, which refers to the latest glacial epoch, the Pleistocene Epoch.

any of a series of climatically cold periods marked by alternating periods of glaciation and warming

A glacial epoch or time of extensive glacial activity

Numerous ice ages have occurred, but this term usually refers to the last great Ice Age (2.4 mya to 10 kya).

A period in the Earth's history during which a colder and wetter climate led to growth of glaciers and extensive ice sheets over northern North America and Europe. There have been several ice age [..]

Periods in the history of the earth characterized by a growth of the ice caps towards the equator and a general lowering of global surface temperatures, especially in temperate mid-latitudes

a long period of climatic cooling during which the continents are glaciated repeatedly

A period of long-term reduction in the earth’s temperature, resulting in the growth of polar ice sheets and glaciers. There have been at least four ice ages in the past separated by warmer interglacia [..]

scientific: A period of long-term reduction in the temperature of Earth's surface and atmosphere, resulting in the presence of polar ice sheets and alpine glaciers. colloquial: Any of several gla [..]
