answer:

C IS the answer

sea breeze

explanation:

cool air is going towards land allowing for the land to be cooler, the hotter air gets pushed away from the land.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
