Why is it called Arabia Terra?

These streaks are thought to form by dust moving downslope in a way similar to snow avalanches on Earth. 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 located?

Mars
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.

What is the deepest canyon on Mars?

Valles Marineris
Valles Marineris: The Grand Canyon of Mars. The largest canyon in the Solar System cuts a wide swath across the face of Mars. Named Valles Marineris, the grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep.

What is Hellas Planitia and how did it form?

Hellas Planitia is thought to have been formed during the Late Heavy Bombardment period of the Solar System, approximately 4.1 to 3.8 billion years ago, when a protoplanet or large asteroid hit the surface. The altitude difference between the rim and the bottom is over 9,000 m (30,000 ft).

Which is lower western Arabia Terra or west Arabia Terra?

When the researchers began studying maps from the new data, they noticed that one region, western Arabia Terra, is a kilometer lower than the rest of the highlands and borders the lowlands to the north.

Where is the Arabia Terra region 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.

How did Arabia Terra get its name from?

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.

Is there an ice sheet in 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.
