1. A shallow earthquake of 7.6 magnitude occurs along a colliding plate boundary in the Pacific Ocean. They immediately send tsunami warning signals to countries along the Pacific Ocean. Why are tsunami warnings
sent out when this type of earthquake occurs? In your explanation, make sure to include: why this type of
earthquake could cause a tsunami to form and how the resulting tsunami forms.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

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.
