Once upon a time, a curious explorer named Sam set off on an adventure to learn about landforms. His first stop was the mighty mountains. He learned mountains are formed when two plates on the earth's crust push together. He discovered the highest mountain is Mount Everest! Next, he visited the beautiful beaches. Here, he learned that beaches are formed by the erosion of rocks, and the tiny pieces are called sand. He built a sandcastle and took a dip in the ocean. Then, it was time to explore the deep valleys. Valleys, he found out, are low areas between mountains or hills. He was amazed by the Grand Canyon, a famous valley! In the end, Sam returned home. His adventure had been exciting and educational. He had seen fantastic landforms and learned so much. Sam couldn't wait for his next adventure!
