Ice Age on Earth – Facts for Kids

The ice age was a period of glacial change in the Earth’s climate from 2,700,000 years ago to 10,000 years ago, during which the continents of North America and South America

Ice Age Facts for Kids

The term ice age is often used interchangeably with glacial age, meaning a period in Earth’s history during which the average temperature on the surface of the planet is below freezing. Glaciation, as well as the associated glaciations, refers to the accumulation of massive amounts of snow and ice. During these glacial periods, vast amounts of ice are deposited over vast areas. This causes the continents to shift and cause changes to the surface features of entire continents. Many major ice ages have occurred throughout Earth’s history. 

Glacial stages are minor or intermediate stages within a glacial cycle. A lesser, recent glacial stage called the Little Ice Age began in the 16th century and advanced and receded intermittently over three centuries in Europe and many other regions. Glaciers in Antarctica have reached their maximum development, which began about 1750 and continues at about the same rate as before. Ice sheets were more extensive during the last glacial period than at any time in the last million years.

How an Ice Age Changes Earth

There are many types of changes to the earth’s surface caused by an ice age. One example is the formation of glaciers. As winter temperatures drop, plants at higher latitudes in the northern hemisphere are driven to the south.

While sea levels are dropping, the emergence of lakes and river valleys have created huge inland seas that can no longer be reached by oceanic currents, with new land bridges emerging between continents. Glaciers grow slowly when they are colder than the surrounding region. As temperatures warm, they begin to melt, and as they do, their weight becomes more and more concentrated in the centre, which creates a funnel-shaped trough called a glacial valley.

Pleistocene Epoch: Facts About the Last Ice Age

This is when humans lived in a place called Ice-Age Europe, where the temperature was cold enough for the ice caps to grow. This period of time, known as the Pleistocene epoch, lasted from about 2.6 million years ago until about 11,700 years ago. The Ice Age began about 10,000 years ago when the glaciers began their retreat. It ended about 7,500 years ago when the ice began melting again.

The Earth has experienced at least five major ice ages over the last 2.6 billion years. All but the most recent are believed to have taken place during the Pleistocene Epoch (about 3.8 million to 11,500 years ago), and most likely there were many more before humans appeared.

Humans evolved as hominids at the beginning of the Pleistocene Epoch. As we evolved, we spread out around the world. By the end of the Pleistocene, humans could be found on every continent except Antarctica. The Pleistocene Epoch was the first epoch in the Quaternary Period and the sixth in the Cenozoic Era. In order to better understand this new chapter in human history, I recommend the book “The New World Order” by William H. Hartmann, which was published in 1973.
