1. Atlantic Coastal Plain:
- Majority of Delaware's land area lies within the Atlantic Coastal Plain.
- The Coastal Plain is characterized by low, flat topography with gently rolling hills.
- The soils are primarily sandy and fertile, making the region suitable for agriculture, especially in areas known as "The Delaware Sandbarrens" to the south.
2. Piedmont:
- The Piedmont region comprises the northern part of the state.
- It features rolling hills and valleys with occasional ridges and streams.
- The soils are typically rocky, with a mix of clay and loam, less fertile compared to the Coastal Plain.
- Wilmington, Delaware's largest city, is located in this region.
3. Appalachian Plateau:
- The Appalachian Plateau encompasses the westernmost part of Delaware, covering a small area near the state's border with Pennsylvania.
- It is characterized by higher elevations, with hills rising to over 400 feet (122 meters).
- The soils are typically stony and less fertile, making this region less suitable for agricultural purposes.
Overall, Delaware's terrain is relatively flat, with the majority of the state lying at low elevations. The state's highest point of 448 feet is significantly lower compared to other states in the region. The varied terrain of the Atlantic Coastal Plain, Piedmont, and Appalachian Plateau contribute to Delaware's diverse landscapes, ranging from sandy beaches and fertile farmlands to rolling hills and wooded forests.
