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.
Answer:
One way forests were revived was from the replanting of many local trees, such as conifers, spruce, etc. This resulted in blooming and mass regrowth of forests. Another way forests were returned to their healthy condition was from redirecting species such as cattle away from the shrubbery, which allowed saplings to grow safely. A third way that people revived forests was by enabling a fire restriction. By keeping fires away from these precious forests, the trees could grow without harm.
