A series of satellites that orbit Earth and collect surface data are part of a NASA project called Landsat. These satellites are able to collect data to help determine regional biomes and how such biomes can change. The satellites send information back to Earth. Scientists can take the data and create colored maps that represent certain properties of a region. A Landsat image of the northern part of South America is shown below.

How is Landsat most likely being used to produce data in this map?
A. The satellites are able to distinguish region W from region Y based on soil moisture.
B. The satellites are able to distinguish region Z and region X based on the amount of cloud cover.
C. The satellites are able to distinguish region Y from region Z based on elevation of the land.
D. The satellites are able to distinguish region X from region W based on how close they are to oceans.
