What is the movement of land masses during history of the Earth and what is the transition fossil that has both reptile and bird features?

The movement of land masses on Earth is known as plate tectonics, which is the theory that the Earth's outer shell is divided into several plates that glide over the mantle. These plates are constantly moving and interacting with each other, leading to the formation of mountains, earthquakes, and volcanic activity.

The transition fossil that has both reptile and bird features is Archaeopteryx. Archaeopteryx is considered a transitional fossil because it exhibits characteristics of both reptiles (such as teeth and a long bony tail) and birds (such as feathers and a wishbone). This fossil provides evidence for the evolutionary link between dinosaurs and birds.
