Answer:
The Moon is significantly smaller than the Earth and so its core contained less energy to begin with and also cooled significantly faster. Thus, the Moon's core is relatively cool and solid, whereas a portion of the Earth's core is liquid.
Explanation:
When a volcano erupts, the molten rock (or magma) that comes out of the Earth is called lava. Because lava is so hot (more than 1,100 degrees C, over 2,000 degrees F), it remains molten and flows across the ground until it cools and hardens into rock.
