Answer and explanation:
a) The plate tectonics is a theory that suggests that Earth's outer shell is divided into several plates that glide over the mantle (rocky inner layer above the core), there are seven major plates that make up 94% of the Earth's surface and many smaller plates making up the other 6% (I annexed a map of those tectonic plates). The tectonic plates are in motion (presumably since the beginning of time), the movement of the plates creates three types of tectonic boundaries:<em> convergent </em>(plates move into one another); <em>divergent </em>(plates move apart); and <em>transform</em> (plates move sideways in relation to each other).
b)The Mid-Atlantic Ridge (MAR) is a divergent tectonic plate or constructive plate boundary located along the floor of the Atlantic Ocean. <em>The MAR developed as a consequence of the divergent motion between the Eurasian and North American, and African and South American Plates</em>
c) In areas where the plates come together, sometimes volcanoes will form, they can also form in the middle of a plate, in places called "hot spots" where magma rises upward until it erupts on the seafloor. The Hawaiian Islands<em> were formed by such a hot spot occurring in the middle of the Pacific Plate.</em>

Answer:
Eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves; this evidence led scientists to look again at Wegener's hypothesis of continental drift. ... Eruptions of molten material, which results in continent material is a piece of evidence of seafloor spreading.
