question 3
what does a geographic information system (gis)
do?
a it allows geographers to communicate
instantly.
b it shows different layers of information on a
map.
c it displays earth without distortion.
d it uses satellites to show a persons location.

Explanation:

A Geographic Information System (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. One of its key features is the ability to display multiple layers of information on a map. For example, it can overlay layers like population density, land use, and elevation on a base map. Option A is incorrect as GIS is not mainly for instant communication among geographers. Option C is wrong because no map (including those from GIS) can display the Earth without any distortion. Option D describes a Global Positioning System (GPS) rather than a GIS.

Answer:

B. It shows different layers of information on a map.
