Part D This is a map of Yosemite National Park. Look for areas on the map that could be prone to mass movements. In which area could a mass movement prevent people or wildlife from accessing the resources they need? Explain your reasoning. ​

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
