Acontour interval of 20 feet means that every foot on a given topographic map represents 20 feet on the earth. true or false? i think the answer is true, but then again i didn't really understand the lesson. you for your

False

Contour lines on a map are lines of constant elevation above sea level. The "contour interval" is the vertical distance represented by adjacent contour lines.

The horizontal distance between contour lines on a map depends on the slope of the terrain. Lines are closer together when th slope is steep. The amount of distance on the ground that a distance on the map represents is determined by the scale of the map, not the contour interval.

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
