Which of the following is not true about sedimentary rocks? a. they formed through compaction and cemintation b. they are made up of sediments c. they formed from igneous rock fragments d. they are not part of the rock cycle (15points! )

The correct answer option is D. They are not part of the rock cycle.

Explanation:

The rock cycle is the transitional process where the rocks of a particular type change and turn into rocks of another type.

The breaking down of different rocks like igneous andmetamorphic and then the cementation and compaction of these broken rock pieces forms the sedimentary rocks.

Therefore, saying that sedimentary rocks are not a part of the rock cycle would not be true.

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.
