The convergence between a continental plate and an oceanic plate is subduction process where the denser oceanic plate force the thinner continental plate to sink into the mantle.

Answer: Option (D)

The type of volcanism formed the Andean Mountains in South America is due to subduction process. It is due to the converging of Nazca Plate over Antarctic Plate due to gravity and made them to sink below the South American Plate. 

This process still continues today and due to the activity, it causes volcanic eruptions and earthquakes in that region. It was reported about 150 - 160 (approx.) active volcanoes in the Volcanic Belt of Andes.

According to this map, how did the United States answer the Soviet threat of missiles in Cuba?

Liula [17]

The correct answer is - by blockading the island with aircraft carriers.

After Castro came to power in Cuba, he immediately made an alliance with the Soviet Union. That was a devastating news for the United States, as that meant that their arch rival will be able to make its basis right next door to their territory.

The United States responded by blocking the island as much as possible, by using numerous aircraft carriers that circled around the island, they were trying to threaten them, and also to be able to block or to respond quickly to any attack from Cuban territory.
