a permanent marker on the ground that indicates location and elevation.

To show topography in a rugged, mountainous area, the most appropriate contour interval would be 5 feet. 10 feet. 20 feet. 100 feet.

100 feet.

To show topography in a flat coastal area, the most appropriate contour interval would be 5 feet. 10 feet. 20 feet. 100 feet.

5 feet.

Contour lines on a topographic map are spaced at equal distances from one another horizontally. cross one another at rivers. cannot cross. cannot be drawn below sea level.

cannot cross.

Small tick marks (hachures) on contour lines indicate steep slopes. gentle slopes. hilltops. depressions.

depressions.

Contour lines on a map connect points spaced equal distances from one another. of equal elevation. of interest to geologists. that mark uphill or downhill trails.

Information on the borders of a topographic map includes all except the year the map was made. the map scale. the cost of the map. the latitude and longitude of the four corners of the map.

the cost of the map.

A map scale of 1:24,000 means that one inch on the map = 24,000 inches on the ground. one centimeter on the map = 24,000 centimeters on the ground. one foot on the map = 24,000 feet on the ground. All of the above.

All of the above.: one inch on the map = 24,000 inches on the ground. one centimeter on the map = 24,000 centimeters on the ground. one foot on the map = 24,000 feet on the ground.
