What is the largest volcano on Venus?
Theia Mons
Theia Mons is the largest volcano on Venus. It is located in Beta Regio, and is shown here in the bottom center. Theia is over 4 km high, and its lava flows cover an area more than 800 km wide.
What is the name of Venus’s volcano?
A volcano named Sapas Mons dominates this computer-generated view of the surface of Venus. Lava flows extend for hundreds of kilometers across the fractured plains shown in the foreground to the base of the mountain, which measures 248 miles across 0.9 mile high.
What are coronae on Venus?
In planetary geology, a corona /kəˈroʊnə/ (plural: coronae /kəˈroʊniː/) is an oval-shaped feature. Coronae appear on both the planet Venus and Uranus’s moon Miranda and may be formed by upwellings of warm material below the surface.
Are there giant volcanoes on Venus?
Venus has more volcanoes than any other planet in our solar system. Previous research suggests that Venus possesses more than 1,600 major volcanoes, and could have more than 100,000 or even more than 1 million smaller volcanoes.
Does it rain on Venus?
Since Venus does not experience rainfall (except in the form of sulfuric acid), it has been theorized that the lightning is being caused by a volcanic eruption.
What are Venus’s volcanoes like?
Venus has shield volcanoes, widespread lava flows and some unusual volcanoes called pancake domes and “tick-like” structures which are not present on Earth. Pancake dome volcanoes are up to 15 km (9.3 mi) in diameter and less than 1 km (0.62 mi) in height and are 100 times the size those formed on Earth.
Do all planets have a corona?
How do pancake domes form?
They usually have a central pit- or bowl-like feature similar to a volcanic crater, but it is thought that these pits form after the eruption as the lava cools and emits gas rather than being a vent from which the lava originated. The surface of pancake domes are covered with patterns of small cracks and faults.
Is there a planet named corona?

What are pancake domes on Venus?
A pancake dome is an unusual type of lava dome found on the planet Venus. They are widely scattered on that planet and often form groups or clusters, though with smaller numbers of pancake domes in each group than is typical for the more common shield volcanos.
Do all planets have lava?
Evidence of past volcanic activity has been found on most planets in our solar system and on many of their moons. Our own moon has vast areas covered with ancient lava flows. Mars has Olympus Mons and Tharsis Rise, the largest volcanic features in our solar system.
