Answer 1

Claim: Venus's rock transformation processes form mostly igneous rock. Evidence: Radar mapping by the Magellan spacecraft and surface measurements from Soviet Venera landers reveal vast lava plains, numerous volcanic features, and predominantly basaltic rock compositions consistent with extensive volcanic resurfacing. Evidence: The relative scarcity of river-like drainage, the absence of stable surface oceans, and a crater distribution consistent with episodic global resurfacing argue against widespread sedimentary deposition. Reasoning: Igneous rocks form directly from cooled magma and lava, so repeated, planet-scale volcanic activity produces large volumes of basaltic igneous rock on Venus. Because persistent liquid water and processes for transporting and lithifying sediment are essentially absent on Venus, sedimentary rock formation is minimal and igneous processes dominate the planet’s rock record.
