It's common knowledge that the atmosphere of Venus is too inhospitable for a proper landing. The most concerning problem with that is pressure. Venus's atmospheric pressure is said to be 92 times heavier than Earth's. Despite this, according to Basic Planet, Venus boasts some impressive geography:
It does have a lot of volcanic plains with this covering almost 70 percent of the planet. There are two highland areas or continents are they can be known as; one of which lies towards the northern part of the planet and the second is near to the equator of the planet. The north continent is named Ishtar Terra and it is thought to be around the size of the country Australia; and has a high mountain of Maxwell Montes. The Aphrodite Terra is located near the equator and is quite bigger than the north continent which is thought to be around the size of South America.
Though, without there being any lava flow evidence seen on any part of the planet, it has baffled many because with there being volcanic activity, most would have believed lava would have occurred. Though, the planet has to be very young because it doesn’t have a lot of crater impacting the surface which could mean the planet is only around a few hundred million years old.
Due to a lot of volcanic activity, it has helped to shape the surface of the planet and interestingly it is home to hundreds more volcanoes than that on Earth. This doesn’t mean that Venus is going to have a higher amount of volcanic activity than that on Earth but since the crust on the planet is older, there are more volcanic shapes formed. Of course throughout the years, there have been many studies over the volcanic activity on Venus and there have been many programs from Russia throughout the years to note the changes in the planet’s system and how volcanic activities range.
In an alternate universe, Venus is much bigger--175% wider than Earth and 5.5x as massive. Which means an even heavier atmosphere (say, 1200 times heavier than Earth's). Would this extra-extra pressure affect Venus's geography and topography in any way?
