The shape of the land determined by elevation, relief, and landforms.

The difference in elevation between the highest and lowest parts of an area.

A feature of topography formed by the processes that shape earth surface.

A landform made up of flat or gently rolling land with low relief

A landform with high elevation and high relief.

A group of mountains that are closely related in shape, structure, are, age.

A large landform that has high elevation and a more or less level surface.

A large area of land, where the topography is made up of mainly one type of landform.

A sphere that represents Earth's entire surface.

A flat model of all or part of Earth's surface as seen from above.

Converting information to numbers for use by a computer.

One bit of a digitized image, often appearing as a small square or dot.

A photo taken by cameras mounted in airplanes.

Global Positioning System

A navigation system that uses satellite signals to locate a radio receiver on Earth’s surface.

Geographic Information System

A system of computer hardware and software used to produce interactive maps.

A map that shows the surface features of an area.

A line on a topographic map that connects points of equal elevation.

The difference in elevation from one contour line to the next.

On a topographic map, a heavier contour line that is labeled with elevation of that contour line.
