Era

Paleozoic-its end was marked by mass extinctions

mesozoic-between cenozoic and paleozoic

cenozoic- most recent era

period-a length of time

epoch-age

mass extinction- a huge die off of animals

landbridge- a strip of land connecting two large land masses

geographic isolation-island

Explanation:

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
