The answer is the first one
Answer:
Explanation:
Una estrella de unas 38 veces la masa del Sol y otra ligeramente inferior, de unas 32 masas solares, están tan cerca que comparten una única envoltura. Ambas orbitan alrededor de un centro de masas común, y acabarán fusionándose en una única estrella supermasiva, dicen los científicos, de unas 70 veces la masa del Sol. “Será dentro de algunos millones de años, ni siquiera decenas de millones de años, y tenga en cuenta que eso no es apenas nada en términos astronómicos… nuestro Sol tiene 4.500 millones de años de vida”, explica a EL PAÍS Javier Lorenzo, astrónomo de la Universidad de Alicante y líder del equipo que ha descubierto y caracterizado está sistema binario. MY Camelopardalis, situado, en la constelación de la Jirafa, está a una distancia de entre 12.000 y 15.000 años luz de la Tierra, en nuestra galaxia.
The geological feature responsible for the volcanic activity in this part of the world is the convergent tectonic boundary between the North American tectonic plate and the Pacific tectonic plate.
The Aleutian Islands are part of the so called ''Ring of Fire''. This means that they are part of the most active volcanic chain in the world. This is due to the convergent boundaries between the Pacific tectonic plate from one side, and the North American, South American, Eurasian, and Australian tectonic plate from the other side. The Pacific plate is submerging bellow all of them, and this contributes to the release of lots of magma and pressure towards the surface of the Earth, thus creating volcanoes in close proximity to the tectonic boundaries.
Eastern boundary currents are associated with the cooling off of the ocean waters. These currents originate from both of the poles, they bring cold, shallow, slow water towards the lower latitudes and cools of the water near the Equator. Once there they are warming up and move in the opposite direction as westward warm currents.
