During the winter, many species of amphibians and reptiles go into a hibernation-like state called overwintering. they eat little or no food, slow their metabolism and breathing rate dramatically, and most of their bodily functions shut down. interestingly, many of these species choose to spend the winter underwater. why might it be advantageous to overwinter at the bottom of a pond rather than on land?

the answer is a) a shiprock was formed by igneous process

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.
