Explanation:
1:- The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.
2:- Most earthquakes occur along tectonic plate boundaries, along cracks in the lithosphere called faults, or along the mid-oceanic . Earthquakes are recorded by a seismographic network. Each seismic station in the network measures the movement of the ground at that site. ... The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake.
