Why is it called Arabia Terra?
Arabia Terra was named in 1879 after a corresponding albedo feature on a map by Giovanni Schiaparelli, who named it in turn after the Arabian peninsula.
Where is Arabia Terra?
Arabia Terra is a large upland region in the north of Mars located mostly in the Arabia quadrangle. It is densely cratered and heavily eroded. This battered topography indicates great age, and Arabia Terra is presumed to be one of the oldest terrains on the planet.
Where is Olympus Mons located?
Mars
Olympus Mons is a shield volcano located in Mars’ western hemisphere. It is the largest volcano in the solar system at 72,000 ft tall (two and a half times the height of Mount Everest) and 374 miles wide (nearly the size of the state of Arizona).
What is Terra on Mars?
The battered region of Arabia Terra is among the oldest terrain on Mars. A dense patchwork of craters from countless impacts testifies to the landscape’s ancient age, dating back billions of years. In eastern Arabia lies an anonymous crater, 120 kilometers (75 miles) across.
What created Valles Marineris?
Most researchers agree that Valles Marineris is a large tectonic “crack” in the Martian crust, forming as the planet cooled, affected by the rising crust in the Tharsis region to the west, and subsequently widened by erosional forces.
Can Olympus Mons erupt?
Olympus Mons is a shield volcano. Rather than violently spewing molten material, shield volcanoes are created by lava slowly flowing down their sides. As such, Olympus Mons may still be an active volcano with the potential to erupt.
What kind of terrain is Arabia Terra on Mars?
Arabia Terra is a large upland region in the north of Mars that lies mostly in the Arabia quadrangle, but a small part is in the Mare Acidalium quadrangle. It is densely cratered and heavily eroded. This battered topography indicates great age, and Arabia Terra is presumed to be one of the oldest terrains on the planet.
How big is the crater in Arabia Terra?
A single small crater of about 22.6 meters (about 74 feet) in diameter is surrounded by light and dark-toned ejecta – indicating that this impact excavated to a depth where light colored strata exists. The crater occurs near 20.6 degrees north latitude, 356.8 degrees west longitude, in Arabia Terra.
Is there an ice sheet in Arabia Terra?
Arabia Terra. Ice sheet in Oxus Patera, a caldera in Arabia Terra. The scalloped nicks along the spines of the caldera’s ridges are likely cracks caused by the expansion and contraction of ice. Arabia Terra is a large upland region in the north of Mars that lies mostly in the Arabia quadrangle, but a small part is in the Mare Acidalium quadrangle.
When did the meteorite hit in Arabia Terra?
A meteorite impacted in Arabia Terra some time between 30 June 2002 and 5 October 2003. A single small crater of about 22.6 meters (about 74 feet) in diameter is surrounded by light and dark-toned ejecta – indicating that this impact excavated to a depth where light colored strata exists.
