The mantle, or part of the earth below the crust and above the core, is believed to be molten (hot liquid) granite and basalt. what is the best explanation for this? select one: a. the heat trapped in the core dissipates into the mantle as thermal energy. b. the force of gravity from the mass of the earth forces the molecules very close together. c. the heat trapped beneath the crust is dissipated through volcanic eruptions. d. the force of gravity from the mass of the earth prevents the heat from dissipating through volcanic eruptions.
