When molten magma flows from the core of the Earth to the crust and cools, it forms igneous rocks.

Differentiate between sidereal and synodic moon month:
A sidereal month is the time it takes for the moon to complete one orbit around the Earth relative to the stars, which is about 27.3 days. On the other hand, a synodic month is the time it takes for the moon to complete one cycle of phases, such as from new moon to new moon, which averages about 29.5 days. The difference between the two is due to the Earth and moon moving in their respective orbits around the Sun.
