Charles Hutton invented contour lines while trying to make order of scores of measurements taken by surveyors for the purpose of finding the mass of Mount Schiehallion in the central Scottish Highlands in 1774.

No, elevations of 300' and 350' would not appear on the same contour line isoline on a topographic map. Contour lines represent the same elevation throughout the line, so different elevations would be on different contour lines.
The difference between an outline and a contour line is location. An outline is used to draw the outermost form on an object, while a contour line is used to depict details inside the form of an object.
Contour interval.
A contour line is a line on a map connecting points of equal elevation or depth. Contour lines help visualize and understand the shape of the land by showing the topographic features like hills, valleys, and plateaus. These lines make it easier to interpret the terrain and plan routes in outdoor activities.
Contour lines or also known as isohypses, connect points of equal elevation on a map. Contour lines can be curved, straight or a mixture of both. The lines on a map describe the intersection of a real or hypothetical surface with one or more horizontal planes.

An Index Contour
An index contour is a thicker contour line that is labeled with the elevation of that contour. It usually appears every fifth contour line and helps to quickly identify elevation changes on a topographic map. Regular contour lines are thinner and connect points of equal elevation.
When a V-shaped contour line points downhill, it means that the contour line is under very low elevation. And incase your wondering about when the contour line is uphill, it means that the elevation level is very high.
The first contour line was created by Charles Hutton in 1771. He used contour lines to map a coal mine.
A depression contour is a contour line that represents a lower elevation compared to the surrounding terrain. A contour line is a line on a map connecting points of equal elevation, indicating the shape of the land surface.
