Best Answer

Contour maps are used to show the below ground surface of geologic strata, fault surfaces (especially low angle thrust faults) and unconformities. Isopach maps use isopachs (lines of equal thickness) to illustrate variations in thickness of geologic units.

Which shape would a cross section of earth cut from pole to pole reveal?

My $210 Physical Geography class text book does not have the answer. It just says it would be smaller than the diameter of a cross section through the equator.

What difference between revolved section and removed section?

A revolved section is made by revolving a cross section view 90° about an axis of revolution and superimposing the section view on the orthographic. A removed section is similar except the view is removed to another part of the drawing. : )
