Iceland is a unique land mass, as it gives scientists the opportunity to study processes that normally occur at a submerged (underground) divergent plate boundary. the diagram shows that two tectonic plates meet in iceland: the north american and the eurasian plates, as shown in the diagram below. as these plates drift away from one another, a rift (like those normally found on the ocean floor) will be created. what chain of events will most likely occur to iceland in the future?

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
