The earth was a single land mass which drifted apart and formed several continents. Movement of continents is caused by constant shifting and sliding of tectonic plates. Continents move in relation to other continents as they drifted across the ocean bed. Plate movements are caused by extreme heat coming from the core of the earth. Pangea is believed to be a single land mass that held most of today’s continents. The continental drift theory explains that today’s continents were parts of a larger continent that drifted apart.
Once continents drifted apart, similar species would then be separated by large expanses of uncrossable ocean. Earth’s Magnetic Field We use both the measured declination and inclination to determine the location of an ancient magnetic pole (a paleopole) in a rock. This is seen in several animal (Cynognathus, Lystrosaurus) and plant (Glossopteris) species. Today: in Boone, declination is -. 9°, and inclination is 6. 1° Last Year: declination -. 2°, and inclination is 6. 1° Further north, the inclination angle is greater (north Quebec ~77°), further south it is smaller (Miami ~54°) What might it mean if a rock from western NC dated at 100 Ma had an.
Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth's lithosphere, since tectonic processes began on Earth between . and . billion. billion years ago. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century. The geoscientific community accepted plate-tectonic theory after seafloor spreading was validated in the late 1950s and early 1960s.
Plate tectonics describes the large-scale motions of the Earth's lithosphere. It covers the concepts of continental drifting, which were developed during the 20th century by Alfred Wegener.

In a compromise between Anderson's (1971) and Golden's (1972) scientific detection approach and Klein's (1972) more rigorous concept orientation, Young begins by tracing the plate tectonics theory from a 17th-century French monk to Canadian geologist Tuzo Wilson, then follows.
