Why is North Dakota so flat?

North Dakota is relatively flat because it was formed by glacial processes and sediment deposits. The landscape was shaped by the Wisconsin glaciation, which covered the region about 10,000 years ago. The glacier deposited large amounts of sediment, including till and outwash, which created the flat topography of the state. Additionally, the state has a relatively low elevation, with an average of about 2,000 feet above sea level, which contributes to its flat appearance.
