Aphrodite Terra

Aphrodite Terra, the Greek name for the goddess Venus, is about half the size of the African continent, and is to be found along Venus' equator.

Aphrodite Terra is different from Ishtar Terra in that, instead of mountain ranges, there are deep rift valleys, resembling the East African Rift Valley and other terrestrial spreading ridges similar to Earth's mid-ocean ridges.

This region of Venus may provide evidence that the planet's surface is in motion like Earth's is.
