nika2105 [10]

Answer:

The map shows the locations of divergent plate boundaries.

Explanation:

There are three main types of plate boundaries, divergent, convergent, and transform plate boundaries. They are defined in accordance with the interaction that the plates have between each other.

On this map, we have marked the locations of the divergent plate boundaries. We have the divergent boundaries between the Eurasian and Africa plates on one side and North American and South American on the other side, between the Pacific plate and Nazca plate, and between the Pacific and Nazca on one side and Cocos plate on the other Last but not least, there is the divergent plate boundary between the Antarctic plate on one side and the Australian, African, and South American plates on the other sides.

What is a star that no longer shines
bazaltina [42]

Answer:

supernova

Explanation:

When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova. The death of massive stars can trigger the birth of other stars.
