Topography describes the arrangement of natural and artificial physical features of an area, including:

* Elevation: The height of the land above sea level.

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

* Slope: The steepness of the land.

* Landforms: Features like mountains, valleys, hills, plains, and plateaus.

* Water features: Rivers, lakes, oceans, etc.

So, when we talk about the "shape of the land," we're talking about its topography.
