Primary landforms are large-scale landforms that are created by the major forces that shape the Earth's crust. These forces include plate tectonics, volcanism, and erosion. Primary landforms include mountains, plateaus, plains, and valleys.
Secondary landforms are smaller-scale landforms that are formed by the erosion and deposition of sediment by water, wind, and ice. These landforms include hills, dunes, and river deltas.
The main differences between primary and secondary landforms are as follows:
* Size: Primary landforms are generally larger in size than secondary landforms.
* Origin: Primary landforms are formed by the major forces that shape the Earth's crust, while secondary landforms are formed by the erosion and deposition of sediment.
* Age: Primary landforms are generally older than secondary landforms.
Here are some examples of primary and secondary landforms:
* Primary landforms:
