Help me pls geography don’t understand

Question 6 False they're about 12 plates.

Question 7 True they do that because As plates move, they get stuck in places, and enormous amounts of energy build up. When the plates finally get unstuck and move past each other, the energy is released in the form of earthquakes. Earthquakes and volcanoes are common features along tectonic plate boundaries, making these zones geologically very active.

Question 8 True, because Continental drift describes one of the earliest ways geologists thought continents moved over time. ... He called this movement continental drift. Pangaea. Wegener was convinced that all of Earth's continents were once part of an enormous, single landmass called Pangaea. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.
