Select the correct answer from each drop-down menu. What forms of energy are involved when snow on a mountain breaks loose, resulting in an avalanche? During an avalanche, the energy of the snow on the mountain is converted into energy as the snow cascades down.

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex

a covalent bond, specfically triple bond

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.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
