Final answer:
Earthquakes and volcanoes in the Atlantic Ocean are mainly located along the Mid-Atlantic Ridge, the boundary between diverging tectonic plates that results in the creation of new oceanic crust and is equidistant from the Americas and Europe/Africa. None of the options are correct.
Step-by-step explanation:
The earthquakes and volcanoes found in the Atlantic Ocean are primarily associated with the Mid-Atlantic Ridge, a divergent tectonic plate boundary located between the plates that carry the continents of North America and South America on the western side and Europe and Africa on the eastern side. This ridge is an underwater mountain range that extends from the Arctic Ocean to the southern tip of Africa. Due to the tectonic activities, such as sea-floor spreading, earthquakes and volcanoes are generally found along this middle area of the Atlantic Ocean rather than being close to the continents themselves.
Tectonic movements along the Mid-Atlantic Ridge are responsible for the formation of new oceanic crust, which slowly pushes the Americas away from Europe and Africa. This process is continuous, with the Atlantic Ocean gradually widening over time. Volcanism associated with the Mid-Atlantic Ridge is a direct result of the partial melting of the mantle as tectonic plates diverge. While the Ridge is vast, its activity, including both earthquakes and volcanoes, tends to be in the middle of the Atlantic, equidistant from either continents' coastlines.
Hence, all of the given options are incorrect.
