Major surface features on Venus

Major surface features on Venus

. Most of Venus lies at roughly the same radius, in the lowland, volcanic plains (white areas). The highland massifs (dark areas) include Aphrodite Terra, an elongated feature extending along the equator between 70 degrees and 210 degrees east longitude. All of the elevated regions near the equator mark the sites of extensive volcanism, such as Maat Mons (Fig. 2.27) and Sapas Mons (Figs. 7.16, 7.17). The other main elevated region is Ishtar Terra in the north at about 0 degrees longitude (center top). Ishtar Terra is roughly the size of Australia; the elevated plateau in its western part, Lakshmi Planum, is bounded on all sides by mountain (Fig. 7.18), including Maxwell Montes. This mountain's 11-thousand-meter height above the average radius exceeds by two thousand meters the height of Mount Everest above sea level.
