The lunar highlands are best described as which of the following?

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

Answer: (D)

The main idea here is how the Moon’s surface is categorized by appearance and age. The lunar highlands are the bright, rugged, elevated regions that are heavily cratered and older than the dark maria. They stand out as the Moon’s lighter, mountainous terrain, formed from ancient crust mostly made of anorthosite. The other options refer to features that can appear on the Moon but don’t define the highlands themselves: rilles are channels carved by volcanic or tectonic processes, maria are the dark basaltic plains from ancient lava flows, and craters are impact holes scattered across the surface. So, the best description for the lunar highlands is that they are the high, heavily cratered, light-colored regions of the Moon’s surface.
