Convection occurs in fluids (so both liquids and gases, as well as rheids) and is the concerted, collective movement of groups or aggregates of molecules within the above through advection or diffusion or both at the same time. Convection can never take place in solids and is only specific to fluids.
Two friends are reading books. Jimmy reads a book with 21,356 words. His friend Bob reads a book with one-and-a-half times as many words. Which expression represents the number of words Bob reads?
21,356 x 2
21,356 x one fourth
21,356 x one half
21,356 x one and one half
The appropriate answer is B. DIVERGENT. Divergent margins occur where two oceanic plates are pulling apart or it can occur where a Continental landmass is pulling apart.
As oceanic plates pull apart magma up wells from the mantle and new crust is formed along what is called a spreading ridge. The Mid Alantic ridge is an example of a spreading ridge where new oceanic crust is being formed.

The difference between the two mentioned magnitudes is 4.
A magnitude 1 earth-quack is 10000 times bigger than a magnitude -3 earth-quack. On the other hand, it is 1000000 times stronger in terms of energy release.
Note: To calculate the difference in energy between two earth-quacks, first you calculate the difference between their magnitudes and then you raise 10 to the output you obtain.
