The movement of the tectonic plates is caused by A) convection currents in Earth's mantle. B) the gravity of the iron-nickel core. C) the rotation of the Earth. D) the Moho discontinuity. 3) Which of these pieces of evidence did NOT help in the development of the theory of plate tectonics?

A) The outlines of the different continents look like they could fit together like puzzle pieces. B) Similar fossil evidence has been found on continents separated by great distances. C) Most earthquakes and volcanoes occur along distinct lines around the world. D) No mountains in the world are increasing in size. 4) In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?

A) The strong ocean currents are undermining both areas causing earthquakes. B) Both areas are subjected to strong ocean wind and waves that causes earthquakes. C) Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes. D) Both areas are on the boundary of active plate margins, the motion of the plates causes earthquakes.

The tectonic late concept is given by Alfred Wegener who gave this theory in 1912 and got recognition by 1960 after the presence of the seafloor spreading concept.

The earth has three types of plate boundaries such as convergent, divergent, and transform plate boundaries. These plate or slabs on the earth's crust tends to drift away from each other due to the convective currents coming from the mantel.

Most of the earthquakes and volcanoes are not responsible for the development of plate tectonic theory as they are a result of the collision of plates.

The plates that produce earthquakes have active plate margins that lead to the cause and effect of earthquakes.

Hence the option A, C, and D are correct.
