Answer:
Continental drift theory describes the long term effect of plate tectonics.
Explanation:
The long term result of plate tectonic movement is the continental drift. The continents of Earth lay on tectonic plates, that are in motion and interaction via plate tectonics. The drift of the Earths continent is an ongoing process evident in the rift valleys and seafloor spreading zones.
The theory that  the Earth's continents are dynamic and have drifted relative to each other is known as continental drift which correlates with the theory of plate tectonics.
Every year, the Earth's outer shell plates are displaced by a small amount due to the heat coming from the Earths interior via convection currents.
 
        
             
        
        
        
Answer: f=150cm in water and f=60cm in air.
Explanation: Focal length is a measurement of how strong light is converged or diverged by a system. To find the variable, it can be used the formula:
 = (nglass - ni)(
 = (nglass - ni)( -
 -  ).
).
nglass is the index of refraction of the glass;
ni is the index of refraction of the medium you want, water in this case;
R1 is the curvature through which light enters the lens;
R2 is the curvature of the surface which it exits the lens;
Substituting and calculating for water (nwater = 1.3):
 = (1.5 - 1.3)(
 = (1.5 - 1.3)( -
 -  )
)
 = 0.2(
 = 0.2( )
)
f =  = 150
 = 150
For air (nair = 1):
 = (1.5 - 1)(
 = (1.5 - 1)( -
 -  )
)
f =  = 60
 = 60
In water, the focal length of the lens is f = 150cm.
In air, f = 60cm.
 
        
                    
             
        
        
        
Answer:

Explanation:
