Answer:
The correct answer is B. The scientific term used to describe Mount St. Helens, the Great Lakes, and Death Valley is topography.
Explanation:
Topography is the study of the physical form of a terrain, both on earth, and on other planets and moons. Topography is also the description of the shapes of such surfaces, especially in the form of maps, where altitude differences in the terrain are mapped using level curves.
In its broadest sense, topography is generally concerned with the details of an area, which includes not only the elevation differences of the terrain, but also vegetation and the shape and objects of other organisms created by man. Sometimes it may also include local history and culture.
