Arabia Terra (the Arab Land) is an extensive, cratered highland region north of the equator of the planet Mars .
Its center is 25 ° north latitude and 330 ° west longitude . The region has an extension of about 6,000 km.
Arabia Terra is exactly opposite to the Tharsis region with its mighty shield volcanoes . Arabia Terra may have been lifted up by internal forces at the same time as the Tharsis region.
The entire region of Arabia Terra is littered with impact craters , the largest (Cassini, Tikhonravov, Schiaparelli) have a diameter of about 200 km.
In September 2004 the Mars Express space probe was able to detect increased levels of water vapor over the region. Obviously there is a large amount of water in the form of ice under the sandy surface.
The vast Vastitas Borealis plain extends north of Arabia Terra .
