incoming solar radiation passes through the atmosphere quite freely, whereas terrestrial radiation emitted from the Earth's surface is absorbed and remitted in its upward passage through the atmosphere.
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.
The more direct sunlight an area receives the warmer the temperatures will be, while the indirect sun rays on a certain area cause cooler/colder temperatures.
