Vast, circular to elliptical dark-colored areas on the moon called maria represent very large impact craters filled with basaltic lava. These areas are darker in color than the surrounding areas and are thought to have been formed when large meteorites struck the moon's surface and caused the basaltic lava to flow and fill in the resulting impact basin.
