Which answer choice best describes the difference between folded mountains and fault-block mountains? a. folded mountains form only at divergent plate boundaries, whereas fault-block mountains form only at convergent plate boundaries. b. folded mountains form only at convergent plate boundaries, whereas fault-block mountains form only at divergent plate boundaries. c. folded mountains form when segments of earth's crust are bent and doubled over, whereas fault-block mountains form when stress causes pieces of earth's crust to be thrust upward to higher elevations. d. folded mountains form when stress causes pieces of earth's crust to be thrust upward to higher elevations, whereas fault-block mountains form when segments of earth's crust are bent and doubled over.

The answer is; C

In folding, when segments of Earth's crust are bent and doubled over, the sediments in between are form folds, since they are forced into a smaller space.  This also occurs in converging plates boundaries.

Block Mountains occur when stress due to compression in the crust causes the hanging wall between a fault to move up relative to the footwall.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
