Answer:
1.) The earthquakes are mainly distributed along the edges of the platonic plates on the map.
2.) Pacific Ocean
3.) The distribution of the volcanoes, earthquake epicenters, and major mountain belts are distributed in close proximity of the borders of the tectonic plates. Most of the active volcanoes nowadays are found at the so called ''Ring of Fire'' which is practically the border of the Pacific Tectonic Plate.
4.) Florida and North Dakota are the states with the fewest earthquakes. Antarctica has the least earthquakes of any continent, but small earthquakes can occur anywhere in the World.
5.) The process of plate tectonics may be driven by convection in Earth's mantle, the pull of heavy old pieces of crust into the mantle, or some combination of both. For a deeper discussion of plate-driving mechanisms, see Plate-driving mechanisms and the role of the mantle.
Explanation:
1.) The colored lines show the plate boundaries that may may past each other leading to an earthquake. The map also differentiates the different movements of the plates like rubbing against each other or moving apart. (picture map above)
2.) Sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spot''
