Question

what happens when molten material moves close to the earths core?
o it gets colder and more dense, so it sinks faster toward the core
o it stays the same temperature, so it floats in one place
o it gets warmer and less dense, so it rises toward the crust
o it erupts through the earths surface

Explanation:

The Earth's core is extremely hot. When molten material moves close to it, it absorbs heat, becomes warmer and less dense. According to the principle of density - less dense materials rise above more dense ones in a fluid medium. So, it rises towards the crust.

Answer:

It gets warmer and less dense, so it rises toward the crust
