Answer:
b) the Pacific plate has carried the volcanoes away from the hot spot that formed them
Explanation:
The Hawaiian islands all have volcanic origin. Some are not active, while some still are. All of these islands have been active volcanoes at one point of time, and they have been created by a hot spot that lies beneath the Pacific plate. The hot spot has such a power that it actually manages to break through the central part of the plate where its crust is the strongest and densest. As the magma manages to come out above the water, it manages to create volcanic islands. The Pacific plate though is moving, it is not static, so it drags the volcanic islands away from the hot spot, causing their extinguishing. As those islands are moved away, the hot spot creates new volcanic islands, and the process constantly continuous, resulting in a volcanic island chain.
In the earths mantle the convection currents pass through the mantle which then causes friction in the tectonic plates causing earthquakes,volcanoes or tsunamis

Answer:
Reasons for migration.
Explanation:
Migration is a process that has been happening since the emergence of humankind. The main reasons for it have always been the same - a better life and a safer life. While over time there have been numerous other reasons that have emerged as humans developed more and more, the two basic ones are still the leading ones.
- When the Soviets decided to deny the rigths of the Jews, the Jews felt insecure, both financially and for their lives, so they had a big push factor to migrate to other countries.
- Ethiopia is a country where the living conditions are bad, and when the country faces a severe drought the majority of the population experiences famine. Having a lack of food means that your life is at stake, thus people try to move into countries where they will at least have enough food to survive.
- The war in Bosnia, in which the Muslims, Serbians, and Croatians engaged, resulted in genocides. People were naturally affraid for their lives and the lives of their families, so they did everything they can to migrate to safer countries.
- Haiti is one of the poorest countries in the Caribbean region. The widespread poverty means poor living conditions, so being so close to well-developed countries like the USA motivates the people to migrate in order to have better opportunities and higher life quality.
