The movement of the Earth on its own axis is called Rotation and its movement around the Sun is called Revolution.
The Rotational movement is what results in Day and Night. This is one of the major factors that make Earth life friendly. Working together with the Sun and the Moon, it influences Tides.
The Earth rotates from West to East like most planets (Venus being the exception) and causes the effect of the Sun rising in the East and setting in the West
The Earth does not rotate straight up. It has a tilt in its axis of about 23.5 Degrees which is what what along with the revolution that causes Seasons that we enjoy and endure through the year.
The Earth's rotation also has effect on the creation of the magnetic field that surround the Earth. Yet another reason for our survival. It would be interesting to note that the Moon - Even though it seems never to rotate and we always see only one side of it - indeed rotates. Its rotation period is equal to that of its revolution period around the earth and hence we see only one side.
put it in a hot water then tada! new phase and material, its not paper anymore it already turns into hair dye!
they will still undergo a subduction.
because they are both dense one of them will subduct, and that is the denser type of plate, the older oceanic plate.
