A student models convection currents In a laboratory activity. Water 00 Convection cell Beaker Heat source Now How are the convection currents in the student's model different from the convection currents in Earth's atmosphere and oceans? A The warm air in Earth's atmosphere and the warm water in Earth's oceans sink instead of rise. B The heat source for Earth's atmosphere and oceans is the sun, which heats from above instead of below. C Convection cells in Earth's atmosphere and oceans flow in the same direction instead of opposite directions. D Cold air in Earth's atmosphere and cold water in Earth's oceans are less dense than warm air and warm water instead of being more dense.
