Earthquakes are possible because the tectonic plates around the earth shift and move, converging, diverging, or transforming when in contact with one another. At divergent boundaries, rock layers pull apart, causing . tensional stress
shear stress
compressional stress

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
