Major surface features on Venus

Major surface features on Venus

Fig. 7.12 . 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. Many of the elevated regions near the equator mark the sites of volcanism, such as Maat Mons and Sapas Mons (see Figure 7.16). 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 the western part of Ishtar Terra is known as Lakshmi Planum, which is bounded on three sides by mountains (see Figure 7.17), including Maxwell Montes. This mountain's 11-kilometer height above the average radius exceeds by two kilometers the height of Mount Everest above sea level.
