Quizplus · Accepted Answer

Magma is molten rock that is located beneath the Earth's surface, while lava is magma that has reached the Earth's surface. Therefore, choice C is the correct answer. Choices A and B are incorrect because the color and composition of magma and lava can vary, and choice D is incorrect because lava generally flows more quickly than magma due to lower viscosity.
