is a geological time period during which sheets of ice cover extensive parts of the Earth
Periods in the history of the Earth characterised by a growth of the ice caps towards the equator and a general lowering of global surface temperatures, especially in temperate midlatitudes The most recent ice age ended about 10,000 years ago Ice advances in this period are known to have altered the whole pattern of global atmospheric and ocean circulation
A glacial epoch or time of extensive glacial activity Also, as Ice Age, which refers to the latest glacial epoch, the Pleistocene Epoch (Source: Carbon Dioxide Information Analysis Center, 1990)
any period of time during which glaciers covered a large part of the earth's surface; "the most recent ice age was during the Pleistocene
The latest ice age – the Pleistocene – lasted from 2,000,000 years ago to about 10,000 years ago At that time, there were periods of intensely cold – the glacial stages – during which ice sheets and glaciers extended over much of North America, North-West Europe and Asia, and these were broken by warmer – the Interglacial stages – during which the ice retreated As the glaciers finally retreated, about 13,000 BC, the land was colonised by willow, birch, juniper and small shrubs Cromerian interglacial: 500,000-350,000 BC Anglian: 400,000-300,000 BC Hoxnian interglacial: 250,000-200,000 BC Wolstonian: 180,000 BC Ipswichian interglacial: 120,000 BC Devensian: 110,000 BC Dimlington stadial: 110,000 BC Windermere interstadial: 100,000 BC Loch Lomond stadial: 9000 BC
A period in the earth's history where most of the earth was covered with glaciers
- Any period in the Earth's history during which the polar ice sheets cover much greater areas than they do today During the last ice age (about 10,00 yaers ago) GLACIERS covered much of Britain, for example
The latest ice age - the Pleistocene - lasted from 2,000,000 years ago to about 10,000 years ago At that time, there were periods of intensely cold - the glacial stages - during which ice sheets and glaciers extended over much of North America, North-West Europe and Asia, and these were broken by warmer - the Interglacial stages - during which the ice retreated As the glaciers finally retreated, about 13,000 BC, the land was colonised by willow, birch, juniper and small shrubs Cromerian interglacial: 500,000-350,000 BC Anglian: 400,000-300,000 BC Hoxnian interglacial: 250,000-200,000 BC Wolstonian: 180,000 BC Ipswichian interglacial: 120,000 BC Devensian: 110,000 BC Dimlington stadial: 110,000 BC Windermere interstadial: 100,000 BC Loch Lomond stadial: 9000 BC Flandrian: 10,000 BC See Little Ice Age, Palaeolithic, Prehistoric Calderdale, Animals, Birds, Plants, Stadial, Interstadial
Period of time when glaciers dominate the landscape of the Earth The last major Ice Age was during the Pleistocene epoch
any period in the Earth's history in which polar icesheets have spread to cover regions that are not normally covered with ice The most recent ice age (the Ice Age) occurred from 2 million to 10,000 years ago iceberg floating mass of ice, about 80% of which is submerged, rising sometimes to 100 m above sea level Glaciers that reach the coast become extended into a broad foot; as this enters the sea, masses break off and drift away as icebergs
A period of time, beginning about 2 million years ago, when it was common, from time to time, for glaciers surge down from mountains and form ice sheets At present, glaciers and ice sheets have shrunk back, but it is likely they will grow again
any period of time during which glaciers covered a large part of the earth's surface; "the most recent ice age was during the Pleistocene"
The popular name for the most recent period of glacial activity, also known as the Pleistocene Epoch, which began some 2 million years ago and is still in progress That period which continental glaciers overspread vast regions of northern North America
A period during which the Earth is substantially cooler than usual and a significant portion of its land surface is covered by glaciers Ice ages generally last tens of millions of years
Interval of geologic time between 2 million and 10,000 years ago during which the northern hemisphere experienced several episodes of continental glacial advance and retreat along with a climatic cooling The icing over of Antarctica was also completed during this time
Popular name often given to the Quaternary Period during which large areas were repeatedly covered by ice sheets and glaciers
The Ice Age was a period of time lasting many thousands of years, during which a lot of the earth's surface was covered with ice. one of the long periods of time, thousands of years ago, when ice covered many northern countries. or glacial age Any geologic period during which thick ice sheets cover vast areas of land. Such periods of large-scale glaciation may last several million years and drastically reshape surface features of entire continents. A number of major ice ages have occurred throughout the Earth's history; the most recent periods were during the Pleistocene Epoch (1.8 million-10,000 years ago)
occur over vast periods of time when the climate becomes cold, glaciers develop and much of the land is covered in thick layers of ice and snow The glaciers produced during an Ice Age gradually move through the landscape carving valleys and dramatically changing the shape of mountains The last Ice Age occurred from 1 ½ million to 10,000 years ago in a period of time called the Pleistocene Epoch
