What part of the process of plate tectonics do the water currents represent? what part of the process of plate tectonics do the pieces of paper represent? what was the driving force that caused the pieces of paper to move along the water’s surface?

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.

Gravitational force i believe
