A geochemical cycle that cycles material by mantle convection, subduction, and seafloor spreading
1. Depends because earthquakes are caused by shifting of tectonic plates over one another but moving in general could be either. I would say true. 2. True.
Answer: Option (D)
Explanation: When two oceanic plate moves in opposite direction due to the convection current generated in the mantle, the crust gets thinner and eventually magma comes out to the ocean floor, forming new crust. Due to this divergent movement, a chain of volcanic arc are formed in their vicinity.
For example, the Hawaiian.
Hence the correct answer is option (D).
The distance between the east coast and west coast of Australia is 2,500 mi.
Australia is an island country that is also a continent on its own, and that makes it unique. It is one of the biggest countries in the world, and no wonder that it is a very long and wide country.
In a straight line, Australia's east coast is 2,500 mi away from the west coast of the country.
The biggest and most influential city in the east coast is Brisbane, while on the west coast it is Perth that has that role.
