This illustration of the great ocean conveyor belt shows the movement of surface ocean currents around the globe. what is the effect of these currents on earth's temperatures? weather patterns are more rainy in the south due to the cool currents. there are constantly changing conditions at the equator as a result. temperatures are more stable across the globe due to these cyclical currents. global temperatures constantly decrease due to the movement of warm currents.

doctors i believe if i'm wrong sorry

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

i think the answer is c hope this
