Detailed explanation-1: -What evidence exists for active volcanoes on Venus? The presence of CO2 in the atmosphere on the surface of venus gives evidence that volcanoes are currently active and the presence of SO2 and sulfuric acid clouds.
Detailed explanation-2: -But Mercury doesn’t have much of a molten core. It’s so small that its inner core has completely cooled off by now and is now rock solid. It still maintains a little bit of a liquid outer, core, however, but it’s not exactly big.
Detailed explanation-3: -Mercury: The MESSENGER mission has photographed much of Mercury’s surface and found evidence of volcanic activity shaping its surface. Some of the lava flows are between one billion and two billion years old.
Detailed explanation-4: -As Mercury’s interior cooled, it caused the crust to shrink and be pushed together, break, and thrust upward along faults, making cliffs up to hundreds of kilometers long and over a kilometer high.
