The planet known for having the most active volcanoes is Venus. Unlike Earth, Venus is covered in a thick atmosphere consisting mostly of carbon dioxide, with clouds of sulfuric acid, which obscures its surface. Recent measurements and studies suggest that it has numerous volcanic structures, some of which may still be active. The planet's surface is marked by extensive lava flows and large volcanic plains indicative of past volcanic activity. The heat from intense greenhouse gases promotes volcanic activity, making Venus a fascinating subject of study for understanding volcanism beyond Earth and the evolution of planetary surfaces.
