What is the height of an object above sea level?
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as orthometric heights.
What is difference between altitude and relief?
Altitude is a specific height; relief is the difference between two altitudes. Altitudes are different levels of the atmosphere; relief is the changes that occur between different altitudes.
Is above sea level positive or negative?
Elevations can also be represented by negative numbers. The elevation at sea level is 0 feet. Elevations above sea level are positive and elevations below sea level are negative.
What do you mean by above sea level?
Height above mean sea level (AMSL) is the elevation (on the ground) or altitude (in the air) of an object, relative to the average sea level datum.
What is called relief?
Relief is typically defined as the difference in height between the high point and the low point on a landscape, in feet or in meters. It could also be defined more qualitatively: like "low relief plains" or "high relief rolling hills".
What is mean by relief in geography?
Relief is the variations in the elevation of the ground surface, also features of height above a plain or reference datum. On a relief map, relief is depicted by hachures or shading, or, more accurately, by contours or by spot elevations or both. This relief map shows elevation contours.
What does above mean sea level mean?
The term above mean sea level (AMSL) refers to the elevation (on the ground) or altitude (in the air) of any object, relative to the average sea level datum.
What is the sea level?
Sea level is the base level for measuring elevation and depth on Earth. Because the ocean is one continuous body of water, its surface tends to seek the same level throughout the world. However, winds, currents, river discharges, and variations in gravity and temperature prevent the sea surface from being truly level.

What is relief of the Earth?
'Relief' is the term used for the differences in height from place to place on the land's surface and it is greatly affected by the underlying geology. Relief relies on the hardness, permeability and structure of a rock. High Force waterfall, Teesdale, County Durham.
What is relief short answer?
In geography, a location's relief is the difference between its highest and lowest elevations. For example, with both mountains and valleys in the area, the local relief of Yosemite National Park is impressive. A two-dimensional relief map displays the topography of a given area.
What is relief in geography Wikipedia?
Terrain (or relief) is the third or vertical dimension of land surface. Topography is the study of terrain, although the word is often used as a synonym for relief itself.
What is the meaning of above and below sea level?
