Linea /ˈlɪniːə/ (plural: lineae /ˈlɪnɪiː/) is Latin for 'line'.[1] In planetary geology it is used to refer to any long markings, dark or bright, on a planet or moon's surface. The planet Venus and Jupiter's moon Europa have numerous lineae; Saturn's moon Rhea and Pluto have several.[2][3]
The most striking features of Europa's surface are the series of dark streaks, called "lineae" that crisscross the whole globe
Lineae: The lineae are lines that cross the surface
