The landforms such as mountains, rivers, and valleys that make up the surface features of an area are called topography.

Topography refers to the arrangement of the natural and artificial physical features of an area. This includes:

* Relief: The difference in elevation between the highest and lowest points in an area.

* Landforms: The specific shapes and features of the land, such as mountains, valleys, hills, plains, and plateaus.

* Drainage patterns: The network of rivers, streams, and lakes that shape the land.

* Human-made features: Things like roads, buildings, and other infrastructure.

So, the term topography encompasses all these elements to describe the overall form and shape of the Earth's surface.
