How does the potential-energy diagram for a reaction indicate whether the reaction is endothermic or exothermic? (A) An endothermic reaction has reactants that are lower in energy than products because energy is absorbed to form the products.

(B) An endothermic reaction has reactants that are higher in energy than products because energy is released to form the products.

(C) An exothermic reaction has reactants that are lower in energy than products because energy is released to form the products.

(D) An exothermic reaction has reactants that are higher in energy than products because energy is absorbed to form the products.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
