Question

What is the term that describes a specific location's height above sea level?
A. Elevation
B. Topography
C.Contour
D. Relief

Answer 1

Hint: The height above sea level is used to measure the vertical distance of a location.This is done in reference to a historic mean sea level.

Complete answer: The term that describes a specific location’s height above sea level is called elevation. Since the ocean is a continuous body of water it often tries to find the same level as the earth. However factors such as wind,currents and river discharge and differences in temperature and gravity prevent the sea or ocean from doing so. Therefore the surface of the ocean is often used for measuring elevations which is known as the concept of measuring the ‘local mean sea level’.The sea level is measured in respect to the adjacent land.Sea levels also change along with climate.
Looking at the options:
Option A: Elevation is the term used to define the height above sea level. Therefore this is correct.
Option B: Topography is the study of the forms and features of the earth’s surface. Hence this is incorrect.
Option C: Contour is an imaginary line that joins places at the same height. This is an incorrect answer.
Option D: Relief is known as the vertical and horizontal dimensions of land surface.This is an incorrect answer.
Option A is the right answer.

Note: Due to global warming the glaciers are melting. The melting ice is causing a rise in the elevation of sea level.This is referred to as the rise in sea level.The low lying areas in the world are threatened by the rise in sea level.
