It is not smooth it has craters
The surface of Venus is relatively smooth as it is believed that volcanic action has resurfaced the planet. The surface is composed of rock but we are uncertain exactly what type of rock. There is some evidence that there may be granite on Venus.
Venus' surface is characterized by both smooth plains and rugged, bumpy terrain. The smooth plains are thought to be relatively young lava flows, while the bumpy terrain consists of mountains, volcanoes, and large impact craters.
Venus has few craters, because it is relatively young. Most of the surface is smooth volcanic plains.
Venus is a planet that has a smooth unmarked surface caused by a thick protective atmosphere. The atmosphere of Venus is mostly carbon dioxide, which is surrounded by sulfuric acid clouds.
Yes, Venus has highlands, but they are not as prominent as those on Earth. The planet is dominated by smooth plains and volcanic features, with some elevated regions scattered across its surface. The highest point on Venus is called Maxwell Montes, which is about 11 km (7 miles) above the average surface elevation.
The surface of Venus is mostly rough and bumpy, with thousands of volcanoes, large mountains, and vast plains covered in volcanic rock and impact craters. The surface is also hot enough to melt lead and is shrouded in thick clouds of sulfuric acid, making it one of the most inhospitable places in the solar system.
The planet you are describing appears to be Venus. Its thick atmosphere consists mainly of carbon dioxide with clouds that cause a greenhouse effect, trapping heat and maintaining high surface temperatures. This results in a smooth surface due to intense volcanic activity and atmospheric pressure that erases impact craters.
The "topography" of Venus is the three dimensional shape of the surface of Venus.
The atmosphere on the surface of Venus is cloudy.
Venus only has two continents and they occupy about 8 percent of the surface. Earth's continents occupies about 25 percent of the surface. Venus also does not have any evidence of plate tectonics.
Venus has a solid rocky surface.
