How did wegener explain why fossils of land animals were found on continents that are across oceans from one another?

Alfred Wegener gave the continental drift theory. On the basis of his theory, the world was a solitary compressed protocontinent at the beginning, which afterward got drifted away into distinct continents as seen today. He named this protocontinent as Pangaea that means all the lands. In order to support this theory, he further stated that a land bridge once prevailed between Africa and Brazil, and thus, one can witness identical fossilized animals and plants in the two parts of the planet.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
