What is the purpose of a legend on a map?

Back

A legend explains the symbols and colors used on a map, helping users understand the information presented.

Front

What is distortion in map projections?

Back

Distortion refers to the inaccuracies that occur when representing the three-dimensional Earth on a two-dimensional surface, affecting size, shape, distance, or direction.

Front

What is the difference between active and passive remote sensing?

Back

Active remote sensing sends out a signal and measures the response, while passive remote sensing detects natural energy (like sunlight) reflected from the Earth's surface.

What is the significance of the equator on a map?

Back

The equator is an imaginary line that divides the Earth into the Northern and Southern Hemispheres, serving as a reference point for latitude.
