Question: Imagine you are standing in a farm field in central Illinois. The land is so flat you can see for miles and miles. On a clear day, you might see a grain silo 20 miles away. You might think to yourself, it sure is flat around here. If you drive one hundred miles to the south, the landscape changes. In southern Illinois, there are rolling hills. Why do you think this is? What could have caused these features? There are no big rivers that may have eroded and deposited this material. The ground is capable of supporting grass and trees, so wind erosion would not explain it. To answer the question, you need to go back 12,000 years. Around 12,000 years ago, a giant ice sheet covered much of the Midwest United States. Springfield, Illinois, was covered by over a mile of ice. Its hard to imagine a mile thick sheet of ice. The massive ice sheet, called a glacier, caused the features on the land you see today. Where did glaciers go? Where can you see them today? Glaciers are masses of flowing ice. 

According to the above paragraph, the correct answer to the question "What couldn't the erosion have been caused by?" is "The erosion couldn't have been from wind or rivers"?
Answer: Yes, according to the information provided, the erosion couldn't have been caused by wind or rivers. The differences in landscape - flat terrain in central Illinois and rolling hills in southern Illinois - are attributed to the impact of the glaciers that covered much of the Midwest United States around 12,000 years ago.

Glaciers are large, slow-moving masses of ice that can drastically change the landscape and topography of an area over long periods of time. During the last Ice Age, glaciers covered vast portions of North America. As the glaciers moved, they eroded the land underneath, scraping away soil and rock and leaving a flat surface in their wake. This process likely contributed to the creation of the flat terrain in central Illinois.

In areas where the glaciers retreated or stopped, the ice could have deposited debris left behind, resulting in the formation of rolling hills like those found in southern Illinois. This process, called glacial deposition, occurs when a glacier melts, releasing the accumulated sediment it was carrying. Consequently, the terrain becomes more uneven and characterized by hills and valleys.

As for the last part of the question, glaciers still exist today, although they have retreated significantly since the height of the Ice Age. Presently, you can find glaciers in polar regions like Antarctica and the Arctic, as well as in mountainous areas such as the Andes, the Alps, the Rockies, and the Himalayas. Many of these glaciers are melting at an accelerated rate due to climate change, which poses numerous environmental and societal challenges.
