Ice age.

 Ice age is a period in history of Earth. In that time climate changed on our planet. The temperature became lower in different places.

There were many ice ages: the Huronian (2.4-2.1 billion years ago), Cryogenian (850-635 million years ago), Andean-Saharan (460-430 million years ago), Karoo (360-260 million years ago), and Quaternary (2.6 million years ago-present).

During these periods landscapes and Earth's surface changed. Ice aged influenced many different things on our planet.

At the end of these events some animals became extinct, such as: saber-toothed cats, the mastodons, giant ground sloth, wooly mammoth, and other.

Homo sapiens appeared. Humans created new tools for survival in a cold climate. Also, ancient people developed agriculture.

Geology is a science of study ice age. Scientists named geologists study these important periods. They found plants and animals in large glaciers.

Tales from childhood: Good deeds.

It was a simple winter evening. Sophie was reading fairy tales in her comfortable room. Grandmother was knitting socks for her granddaughters. Snowfall became very strong and temperature fell to -15 C (5 F).

Next day little Sophie and granny decided to walk because the sky was blue. But... roads became very slippery.

Suddenly girl and old woman saw that somebody laid on the slippery ice. Middle-aged woman slipped and fell on the way.

So, grandmother understood that this person needs a doctor. Ambulance appeared several minutes later. Sophie helped woman, too. She gave her a hand with granny.

Two weeks later, in Sophie's school, a woman came from the road. She said a lot of thanks words to teacher and Sophie. All classmates were glad that children can help, too.

Also, woman's injuries almost healed.

Once in early spring tree girls, classmates from elementary school decided to go to the river after classes. Sophie, Kate, and Anne are made in good relations, girls are best friends. It's proposed to Kate, Anne supported, Sophie hesitated but after agreed.

When children arrived to the river girls saw thin ice. Kate stood on the ice. Then Anne joined her friend.

Only Sophie stood on the bank. Little girl seriously pondered her act. But sudden... Anne's feet were in the cold water. Kate stopped jumping and fell. Anne was already waist-deep in the river and crying.

At this moment Sophie was in panic. She didn't know what to do. Several seconds later girl cried "Help!".

Simple man responded to the children's cries and saved them.

When the girls returned home their families scolded them. So Sophie, Kate, and Anne will remember this day for the rest of their life.
