Greta ran to the corner with her older brother Tony. He had money for the ice cream truck in his pocket and she was very happy. The ice cream truck had been parked at the curb waiting for children for a very long time. The ice cream truck driver thought that no more children were coming to get ice cream so he started pulling away from the curb when they got to the corner. They yelled. They screamed, "Stop! Stop!" and jumped up and down on the side walk trying to get him to see them. The driver of the truck saw them, waved at them and smiled, pulled back to the curb and opened his truck up so that they could see everything that he had for sale. They were so excited. They saw some new treats. Tony wanted to try something new. He got an ice cream sundae with chocolate ice cream and nuts. He almost got a snow cone. Greta looked at everything that the ice cream truck had. She saw candy, ice cream cones, snow cones, and everything else. It all looked so good. But after looking at everything, she wanted to get an ice cream sandwich. She got the ice cream sandwich. She bit into it and smiled. It tasted so good. She felt so happy. Her brother, Tony, was happy too. He bit into his ice cream cone sundae and grinned. They walked home with their ice cream and told their mom about how close they came to not getting their ice cream at all. Their mom was happy that the truck had stopped for them. She said that they were very lucky to have gotten to the curb before the ice cream truck left.

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.

Question: "What type of terrain is found South of Central Illinois?"

Response: "Rocky land"

It is not enough to describe some objects by their location. We may also need to know its direction. For example, a wind blows a storm over your school. Where is that storm coming from? Where is it going? How can we describe a direction? The most common way is by using a compass. A compass is a device with a floating needle (Figure 2.1). The needle is a small magnet. The needle aligns itself with the Earth's magnetic field. The compass needle always points to magnetic north. If you have a compass and you find north. You can then know any other direction. See the directions, such as east, south, west, etc., on a compass rose. The Earth has two poles. It has a magnetic north pole. It also has a geographic north pole. These two poles are close to each other but not the exact same place.

Question: "What are the earth's two poles?"

Response: "north and south"
