Detailed explanation-1: -Answer. Answer: The atmosphere of Venus is made up mainly of carbon dioxide, and thick clouds of sulfuric acid completely cover the planet.
Detailed explanation-2: -As a result, the planet’s early ocean evaporated, water-vapor molecules were broken apart by ultraviolet radiation, and hydrogen escaped to space. With no water left on the surface, carbon dioxide built up in the atmosphere, leading to a so-called runaway greenhouse effect that created present conditions.
Detailed explanation-3: -The atmosphere on Venus is much denser than on Earth and is made up mostly (96%) of carbon dioxide and the rest nitrogen. Venus’s radius is 6 051 km and its mass is about 82% of Earth’s mass. The mean (average) density of Venus is about 5.2 g/cm3.
