What are the light-colored regions of the Moon called?

• A. Marias
• B. Highlands
• C. Craters
• D. Rilles

Answer: (B)

Light-colored regions on the Moon are the highlands. They reflect more sunlight because their rocks are lighter in mineral composition, mainly anorthosite, giving them a bright appearance. The highlands cover most of the Moon and are older crust, which is why they’re heavily cratered from long exposure to impacts. In contrast, the dark patches are maria, vast plains formed by ancient volcanic lava that produce a lower reflectivity. Craters are impact-made bowls, and rilles are long channels carved by volcanic or tectonic activity—these are features, not broad bright regions. So, the bright, cratered regions are the highlands.
