Sophia was studying with Maalik about the layers of the Earth. They were given several different statements about the layers. Which statement about the layers would they identify as correct? A-The outer core is less than 70 km in thickness.
B-The crust assists in forming Earth’s magnetic field.
C-The mantle is denser than the crust.
D- Pressure increases when moving from the core to the crust.

I am 95% confident that it is C

because c is a true statement.

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.
