An elevation is a rise or the raising of something. Mountains have an elevation based on how high they are and your mood has an elevation as you get happier.
Elevation is a noun that tells how high something is raised above a surface or ground line. It's also a term for measuring things like temperatures or degrees. Your body temperature might have an elevation if you have the flu, just as the elevation of a hill increases as it gets steeper. Buildings have an elevation too: The front of a building from top to bottom is its front elevation of the structure.
steeper adj. 陡峭的，險峻的
•It helped to eliminate the fussy layers of finely drawn architectural elevations, planning grids and weather maps that cramped her large canvases』 style, scale and apocalyptic mood, and to work more loosely by hand.
