Question

Quizplus · Accepted Answer

Basalt is the most common extrusive rock type for any volcanic environment on Earth or even on the Moon. Basaltic lava is produced when hot, molten basaltic material erupts from a volcano and solidifies into solid rock upon cooling. Due to its low viscosity, basaltic lava can flow for long distances, resulting in extensive lava fields. Basaltic lava flows are widely distributed across the Earth's surface and are also found on the Moon. Therefore, Basalt is the most appropriate answer to this question.
