Topographic Map: A topographic map is a detailed representation of natural and human-made features on the Earth's surface. It uses contour lines to show changes in elevation.
Landforms: Landforms are natural features on the Earth's surface, such as mountains, valleys, plateaus, and hills. They are often formed by various geological processes and exhibit changes in elevation.
Gradient: Gradient refers to the steepness or slope of a land surface. It measures how quickly elevation changes over a given horizontal distance. A steeper gradient indicates a rapid change in elevation, while a gentler gradient represents a more gradual change.
