No. The earth has experienced many glacial periods. The last one, about 10,000 years ago, is often referred to as the Ice Age. About 30% of the earth was covered by ice, most of it in the Northern Hemisphere. Many parts of Africa and South America, in contrast, were warm.
In North America, glaciers covered the ground as far south as Illinois and Missouri.
AnswerAbove is correct, but I did just see a Discovery channel show about an old theory that the earth was totally covered in ice. There are apparently ice scars on rocks in the saharra, and all over to support this, but back then (in the 1800s or early 1900s?) no one could figure out how it could have melted once the ice sheet was complete, reflecting sunlight away. Now we know a volcano could have emited enough green house gases and ash to hold enough heat and darken the ice to melt again. I forget the time frame, but this was way before dinosaurs, so perhaps 1-2 billion years ago? I do recall that the idea is that the earth had evolved some level, then been knocked back to starting single celled organisms a few times. it was all new to me -- not what they taught in college geology in the early 1990s at all.

The times in the past when continental glaciers covered large parts of Earth are known as ice ages. The most recent major ice age, the Quaternary glaciation, began around 2.58 million years ago and continues to the present, with significant glacial advances occurring during the Pleistocene epoch. During these periods, large expanses of North America, Europe, and Asia were covered by thick ice sheets, profoundly impacting global climate, sea levels, and ecosystems.
What are cold periods in earth's history when glaciers covered large parts of earth's surface called?
They are called ice ages :)
What does ice age mean?
An ice age is a cold time period in earth's histor during which glaciers covered large parts of Earth's surface.An Ice-age is a time period between Paleothic & Neolithic era when thick ice sheets covered much of the world.An ice age is any period in Earth's history where polar icecaps were in place. For example, we are currently in an ice age now.It was a time when the world was covered in ice.
What was much lower at the time of ice age?
Global temperatures were much lower during the ice age compared to present times, leading to massive ice sheets covering large parts of the Earth's surface. Sea levels were also significantly lower due to the large amounts of water locked up in ice sheets.
Which parts of the earth were covered by ice sheets?
Ice sheets covered almost all of Canada and parts of the United States, Europe, and South America during each of it's glacial advances.Enormous volumes of the world's water were frozen in these ice sheets.

Ice ages
How much of the the earth was covered in ice during the ice age?
During the ice age, which peaked around 20,000 years ago, about 30% of Earth's surface was covered in ice. This ice covered large parts of North America, Europe, and Asia, forming massive ice sheets and glaciers that shaped the landscape we see today.
Was the entire earth covered in ice during the ice age?
It was not exactly covered in all ice, parts we covered in snow and the whole earth was not all land, parts were water
During the last ice age how much of the earths surface was covered by glaciers?
30%
What area was not covered in ice sheets at the peak of the most recent ice age?
During the peak of the most recent ice age, parts of Africa, Australia, and Central America were not covered by ice sheets. These regions remained mostly ice-free due to their lower latitudes and warmer climates.
How did monkeys lived during the ice ages?
They lived in a similar way to today, in parts of the Earth that were not ice-covered.

What age was a very long period of cold climate during which glaciers covered large parts of the earth?
Ice Age
What parts of the world were not covered with glaciers?
2/3 of the earth is covered by glaciers
What parts of the world were covered with glacier?

What continent was not covered by ice during the Pleistocene ice age?
Africa was not entirely covered by ice during the Pleistocene ice age. Ice sheets predominantly covered North America, Europe, and parts of Asia. Africa experienced a milder climate, with some regions still hosting ice caps and glaciers at higher elevations.
