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.
Well basically it was thin ice but usually a centremetre of snoe
No, even during the various Ice Ages there are always regions that are not that cold.
yes it did.

Ice ages
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.
They are called ice ages :)
Most of Greenland is covered by a continental glacier, so it is permanently under ice. The remainder of Greenland is only snow-covered during parts of the year.
what part of the eye is covered by conjunctiva
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
It was not exactly covered in all ice, parts we covered in snow and the whole earth was not all land, parts were water

They lived in a similar way to today, in parts of the Earth that were not ice-covered.

2/3 of the earth is covered by glaciers

That which is land and the part which is covered by water.
Almost 0%. The only parts of the mantel which cover the earth are those areas where volcanoes are actively pushing lava to the surface. The earth is covered by what is referred to as the "Earth's Crust."

Southern Ohio and even parts of Missouri.
