Volcanoes play an important role in creating land since they are the sources of magma, which once above ground normally cools to create new land. In the ocean, this land normally forms at divergent and convergent boundaries or hot spots. At divergent boundaries (where two plates move apart), magma constantly erupts along a trench deep below the ocean's surface. This magma rarely piles upward and instead is pushed to both sides of the trench. This is how new seafloor forms. Convergent boundaries can create island arcs like Indonesia as magma erupts bit by bit. Hot spots occur in the middle of plates. They are instances where the mantle pierces through the crust and begins to erupt directly onto to seafloor. Over time, these eruptions will pile up and create underwater volcanoes until they potentially make it above sea level, thereby forming an island. This is how Hawaii was and continues to be formed.
Answer:
Difference in longitude = 45–15=30
■ If we start from 0° longitude (Prime Meridian) to east, with one passing longitude 4minutes will added.
■ So, 30 X 4 = 120 minutes = 2 hours ahead
■ So, time on 45°East will be 9 + 2= 11 am.
A disadvantage would be..
1. Over harvesting, harvesting soo much soo quickly resulting in the land losing all it's nutrients.
2. Use of Pesticides/Herbicides
Answer:
ISIS is a jihadist terrorist militia. It controlled territory where more than ten million people lived, in Iraq and Syria. However, the terrorist movement is also active in other parts of the world, including Libya, Nigeria and Southeast Asia. It is known for its well-funded propaganda on websites and social media, with videos of beheadings of soldiers, civilians, journalists and aid workers, as well as the deliberate destruction of cultural heritage.
The group appears to have been established in the early years of the Iraq war, while developing ties with al Qaeda. Then, it separated from Al Qaeda to form its own organization, with the aim of establishing an Islamic caliphate in the territories that at some point belonged to that religion. That is, from Spain to the Middle East.
