Europeans first made contact with America over 500 years ago. But they did not find an empty land. There were tens of millions of people living in America at that time. These people were native to the land and had lived there for thousands of years. The lives of these indigenous people would change when the first settlers from Europe began to arrive. This relationship reached a low point in the 1830s on the Trail of Tears, when Native American nations were forced from their homelands to settle west.

Scientists use many kinds of evidence to study ice ages. One useful method is to study ice cores. Ice cores are samples drilled out from an ice sheet or glacier. These samples provide scientists with ancient temperature information.

Today, understanding Earth’s geologic history is very important. Man-made climate change is causing our planet to change much faster than before. By understanding Earth’s changes, we can understand how life has survived throughout them. This can help us predict what shifts are still to come and how life may adapt in the future.
