Latitude and longitude are measured in pixels, each of which represents 1/360 of the way around a full circle.

FALSE

On a topographic map, steep slopes are indicated by contour lines that are widely spaced.

FALSE

FASLE

Features of topography, such as the Columbia Plateau and Mount Hood, are called

LANDFORMS

. Mapmakers use a framework of lines, called a (n) , to represent Earth's curved surface on a flat map.

MAP PROJECTION
