The movement is called convection, where warm material rises, then cools, then sinks back down.
Answer:
1. Most volcanic islands originate from passive lava flows on the seafloor.
2. These passive flows harden into rock and build up the height of the underwater mountain over millions of years.
3. In addition to magma supply, plate tectonics play a large part in determining which submarine volcanoes will eventually form islands.
4. This volcano, West Mata, erupted in 2009 about 1,219 meters (4,000 feet) beneath the surface of the Pacific Ocean, between Fiji, Tonga, and Samoa.
5. The orange glow of magma is visible beneath the plume of volcanic gases (mostly yellowish sulfur) emitted by West Mata.

Countries with anti-natalist policies are China, India, and Uzbekistan.
Explanation:
The countries can roughly be divided into having pro-natalist or anti-natalist policies. The decision as to which of these two policies is implement depends on the area available, population size, increase or decrease rates, and available resources. Some countries have been swinging between the two policies, setting one for a decade and than turning to the other for a decade, returning to the previous one, and again to the other one, like in the case of Iran.
Some countries that have anti-natalist policies are:
China has such policy for several decades now. Initially it was only one child per family that was allowed, and only few years ago it was allowed for two children by family. The reason for this was the rapid increase of the already huge population and the fear that it will lead to economic and social collapse on the long run. The same problem has been the case in India as well. Even though there are policies that are anti-natalist, the people don't seem to apply to them, though the birthrates have been steadily dropping recently due to the development and gradual increase of the standard of living. Uzbekistan, on the other hand, is castrating the women after they have two children. The reason for this is that the country doesn't have enough resources so they desperately are trying to not become overpopulated and collapse.
