It is actually a simplified view of the earth's rotation because the tilt of the earth's axis with respect to the plane of the earth's orbit means that sometimes sunrise occurs slightly earlier or later along the same longitude.
Metamorphism is the transformation in the existing rock type and means a change in the form when the rocks are subjected to changes in heat and pressure.
Regional metamorphism is also called dynamic metamorphism and foliation occurs when a rock s shortened along the axis during recrystallization. Such as mica, the foliated rocks is a product of the stress that deforms the rocks along the plane.
