In convection current why does magma become more dense when it reaches the crust? a. It heats up
b. It becomes light
c. It cools down
d. It remains the same

beta decay is the answer

the solar system used to have much dust particles option no d

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
