What is the name for the elevation differences between two adjacent contour lines?
A Contour (or contour line) is a line on a map connecting points of equal elevation. A Contour map is a map that shows contour lines. Contour lines are equally spaced. The difference between any two adjacent contour lines is called the contour interval (usually a round number).
What is the name for the elevation difference between two adjacent contour lines a contour interval B elevation C slope D contour loop?
A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines.
What is the difference in height between two places called?
3. The vertical distance between two points is called the difference in elevation , which is similar to what you have learned as the difference in height (see Section 5.0).
How are differences in elevation represented?
They can be shown on maps by contour lines, which connect points with the same elevation; by bands of color; or by numbers giving the exact elevations of particular points on the Earths surface.
What is the difference in elevation between point A and point B?
The difference in elevation between point A and point B equals BC or (AX- BY) or (backsight BS – foresight FS ).
What is the difference in elevation from one index contour to the next?
The difference in elevation between one contour line and the next is called the contour interval. The contour interval is selected based on the relief of the area being mapped.
What is contour gradient?
Explanation: Contour gradient is a line lying throughout on the surface of the ground and preserving a constant inclination to the horizontal. If the inclination of such a line is given, its direction from a point may be easily located either on the map or on the ground.
What is contour interval of the map?
Individual contour lines on a topographical map are a fixed interval of elevation apart known as a contour interval. Common contour intervals are 5, 10, 20, 40, 80, or 100 feet. The actual contour interval of a map depends upon the topography being represented as well as the scale of the map.
Is there a difference between elevation and altitude?
The elevation of an object is it's height above sea level. Sometimes elevation and altitude are using interchangeable, however, altitude is the vertical distance between an object and the earth's surface.
What is the difference between altitude elevation and height?
Altitude refers to the height of an object above a given point. Elevation refers to the height of a place above the mean sea level.
What is the difference between elevation and altitude?
While all three words mean "vertical distance either between the top and bottom of something or between a base and something above it," altitude and elevation apply to height as measured by angular measurement or atmospheric pressure; altitude is preferable when referring to vertical distance above the surface of the …
What is the distance between contour lines called?
Individual contour lines on a topographical map are a fixed interval of elevation apart known as a contour interval. Common contour intervals are 5, 10, 20, 40, 80, or 100 feet. The actual contour interval of a map depends upon the topography being represented as well as the scale of the map.
What’s the difference between elevation and altitude?
While all three words mean "vertical distance either between the top and bottom of something or between a base and something above it," altitude and elevation apply to height as measured by angular measurement or atmospheric pressure; altitude is preferable when referring to vertical distance above the surface of the …
How do you find the difference in elevation between two points on a topographic map?
You can figure out the elevation of any point by finding the nearest labeled line, counting the number of lines above or below it, multiplying by the contour interval, and adding or subtracting the result from the nearest marked contour line. The more closely spaced the contour lines, the steeper the slope.
What is contour interval and gradient?
In our example, the contour interval is 1m. Define Horizontal Equivalent (HE) Horizontal equivalent is the horizontal distance between two consecutive contour lines measured to the scale of the map. Gradient. Gradient represents the ascending or descending slope of the terrain between two consecutive contour lines.
What is contour interval in geography?
A contour interval is the vertical distance or difference in elevation between contour lines. Index contours are bold or thicker lines that appear at every fifth contour line. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing.
What is the distance between each contour line called?
contour interval A contour interval is the vertical distance or difference in elevation between contour lines.
How do you find the difference in elevation between index contours?

What is the difference between elevation and slope?
To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.
What is the difference between altitude and latitude?
Latitude refers to the distance of a location on Earth's surface from the equator in relation to the North and South poles (e.g., Florida has a lower latitude than Maine); altitude is defined as how high a location is above sea level (think: a city in the mountains has a high altitude).
What is the difference between the highest and lowest elevation called?
The height above sea level of any point on Earth's surface is its elevation. The difference in elevation between the highest and lowest point in an area is called relief.
What’s the difference between two contour lines?
The elevation difference between two adjacent contour lines is called the contour interval (CI). Usually the contour interval is noted on the map legend. In most topographic maps every 5th contour line is drawn in bold print or wider than other contours. Such lines are called index contour lines.
What is topography gradient?
One of the most basic topographic observation that can be made is the gradient (or slope) of the ground surface. High (or steep) gradients occur in areas where there is a large change in elevation over a short distance. Low (or gentle) gradients occur where there is little change in elevation over the same distance.
What is vertical interval of the map?
Noun. vertical interval (plural vertical intervals) (cartography) The vertical distance on the ground which separates adjacent contour lines on a map.
What are the height lines on a map called?
Contour lines are the faint red-brown lines drawn on a map connecting points of equal elevation above sea level, meaning if you physically followed a contour line, the elevation (height of the land) would remain the same. Contour lines show elevation and the shape of the terrain.
How do you find the difference in elevation in surveying?
The elevation is calculated by subtracting the foresight rod reading from the height of instrument. A foresight is the elevation reading of a point of unknown elevation.
What is the difference between height elevation and altitude?
The altitude is the height of an object or point in relation to sea level or ground level; the elevation is the height above a given level, especially the sea level.
What is difference between latitude and longitude?
Latitude implies the geographic coordinates that determine the distance of a point, north-south of the equator. Longitude alludes to the geographic coordinate, which identifies the distance of a point, east-west of the Prime Meridian.
What is the difference between latitude and altitude quizlet?
Latitude is the distance north or south of the equator. Altitude is the height of an object above sea level. Latitude and altitude affect vegetation in similar ways.

What term describes the difference in elevation between the highest and lowest parts of an area? elevation.
