The image below is a cross section through the Earth's interior. Tectonic plates of the lithosphere are shown in grey at the Earth's surface. The Earth's mantle is shown in red-orange. Black arrows in the lithosphere show the directions in which tectonic plates
move. Red arrows in the mantle represent convection currents.

According to the diagram, which of the following is true?

i think the answer is b

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
