If you are reading this it's probably because of your homework, so yes it is true.

Every point on a contour line is at a different elevation?
Every point on a given contour line is at the same elevation. Neighboring contour lines are at different elevations.
What do the lines on a topographical map mean?
The lines that connect points having the same elevation are a kind of isopleth called contour lines, or contours.The closer that the lines are on the map the steeper the terrain is.
How can you find the direction a stream flows on a topographic map?
A contour map shows lines which connect areas equal in height. These lines are called contours and should be labelled to show the height that each contour represents. A stream flows downhill, this is due to gravity. Thus, to determine which way a stream flows, find contours, at least two, that intersect the path of the stream, then look at the heights these contours represents(their labels). The stream will flow from the contour labelled with the higher number towards the contour labelled with the lower number. PS. sometimes not all the contours are numbered, but only say every fith contour is numbered, then you can assume that all contours are equally incremented i.e. the height difference from one contour to the next stays equal.
How do you scientists use topographic maps?
Engineers use a topographic map for every project they are going to build. Topographic maps show altitudes of ground surfaces and also show specific formations, such as mountains. By using a topographic map an engineer can decide the best location for a bridge or building.
What is the use for a topo map?
A topographic map is very useful to show from the sky's point of view the way a city or a field is made. You can see from a distance every layers who made a field or how deep a river is compare to another.
What is a index contour?
A thicker line that has numbers written on it showing the rising or decreasing elevation on a topographic map By Ash Every fifth contour line on a topographic map, usually thicker, used to label elevation.
Is it true that every point on a contour line is at a different elevation?
No. Every point on a contour line has the same elevation.
How on a topographic map how would you show a island in the ocean with an elevation of 80 feet if the contour interval is 10 feet?
You would just add 10 every contour line you pass until you get to the number 80.
What line on a map connects the points of equal elevation?
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.
Every point on a contour line is at a different elevation?
Every point on a given contour line is at the same elevation. Neighboring contour lines are at different elevations.
On a topographic map how would you show an island in the ocean with an elevation of 80 feet if the contour interval is 10 feet?
You would just add 10 every contour line you pass until you get to the number 80.
What is every fifth contour line?
it is a contour line of elevation Control index contour, or just index contour
What shows elevations and land contours?
1) DEM (Digital Elevation Model)This is a shaded image where each shade from white to black (for example) represents a certain elevation. Contour lines can be determined and overlayed on top of the DEM though the use GIS software.2) Topographic MapThis is a type of map that displays contour lines, the spacing of which denotes slope. Every 5th contour line is numbered with the elevation along that line.
How can you find altitudes of locations?
The USGS (the US Geological Survey) prints topographic sheets for every area in the United States. You will find the elevations marked by a number for the highest elevation and by contour lines for the other elevated portions.
What is the contour interval on a orthophoto map?
Contour interval is the actual change in elevation represented by the space between two adjacent topographic "rings". For example, if there is a contour interval of 20 feet, each topographic line on the map represents going either up or down by 20 feet of elevation (and sometimes it's hard to tell which). For convenience, many mapmakers include numbers every four or five lines to tell you what elevation is represented by that line.
Contour plowing and terracing?
Contour plowing is the farming practice of plowing across a slope following its elevation contour lines. On sloped land, contour plowing is done such that rows are side by side but each row follows a path such that every point on it is at the same elevation. So, for example, to plow a round hillock you would plow concentric circles around the hill top to bottom. The resultant furrow lines look just like the contour lines on a contour map. With this plowing method the rows hold water instead of draining it downward and becoming eroded.
What are contour intervals?
Contour lines were first used in the Schiehallion Experiment. This was an experiment designed to find the mass of a mountain, and by calculation, the mass of the Earth!!Contour lines were invented by Charles Hutton, in 1774, as a method of determining (in that case) the volume of the mountain.They are now commonly shown on topographic maps as a method of indicating the shape of the land and the depths of lakes and the sea. The intervals vary according to the need of the map, but common 1:50 000 maps have then indicated every 20 m, with the 100m lines shown slightly bolder.
